Gender bender?

Well, I have COVID and shit, so sorry for late update

___________________________________________________________________

It was a typical day in class. Noisy, everyone chatting with each other, sharing the latest news.

When the bell rang, a teacher who looked like a child entered the classroom.

-Class, be quiet. I have news for you all.

-Aiko-sensei, won't we have a lesson?

-Yes, Aiko-chan, will we have a shortened day?

-Mou, don't call me chan! We just have two new transferred students, that's all.

The class began to make noise, as mid-semester transfer students were extremely rare.

Two girls entered the class - one of them had snow-white hair that was tied in a high ponytail. The other looked like an elementary school student, a real baby. Her hair was silver and her eyes were bronze-golden.

-Please introduce yourself.

-Hai-hai, Aiko-chan-sensei. My name is Kiana Kaslana. I'm glad to meet everyone.

Everyone in the class was mesmerized by the beauty and energy of this girl.

Slightly moving away from the shock, everyone looked at the baby, who was silently standing next to Kiana.

-Hey little sister say something. You can't be so impolite.

Everyone noticed how the little girl began to shake. Everyone chalked it up to her embarrassment. But in reality, she was shaking with rage.

-Hello, my name is Astra Kaslana. Glad to meet you.

Although she smiled, if anyone knew her thoughts, their ears would begin to bleed.

"FUCKING TUNA! BECAUSE OF HER, I AM IN THIS FORM! №%;%№;%№%;. "

Yes, you guessed it right - this girl was our main character.

How did it happen? Let's go back a bit.

Kiana led a wonderful life - eating, sleeping, and doing quests. Returning from one of those, she saw two foxes sleeping under a tree.

Thanks to her emotional connection, Herrscher of Tuna immediately knew that it was Astro.

Without thinking twice, the white-haired girl jumped into a fluffy paradise.

After a while, everyone woke up and Kiana started asking a huge number of questions. But the last question made the protagonist tense.

-You can take on a female form?

-Erm, I think so.

If Astro had been a bit more attentive, he would have noticed how Kiana started drooling after seeing his female form.

Before he could transform back, he heard a phrase that came as a complete shock.

-WE ARE GOING TO THE QUEST RIGHT NOW!

Thus Astro became Astra for a while.

[A month later]

Astro quickly got used to living in a woman's body.

Also, to some extent, he became a mascot of the class - all the girls considered him (or her) their little sister.

The only problems he faced were the perverts. A couple of times they wanted to steal him. To be honest, these guys made the worst decision of their lives. But the main pervert with whom he could not do anything is Kiana.

Sitting on the lap of the white-haired girl, Astro asked a question that had troubled him for a long time.

-Oi, Horny Tuna, when will the quest start? I have already checked the whole world, there can be nothing that's somehow connected to me here.

Naturally, he had to hack all the databases of various governments and so on. In that, he was helped by Iris, who at the moment was a lens worn by the tuna and the baby.

Despite his shapeshifting ability, it was not possible for him to change his eyes. As for the tuna - her ability was limited only by the change of the body size.

-Um, I don't know, gi-

It was at this moment that a magic circle appeared in the class, which moved everyone.

The schoolchildren who saw it were in a panic, so no one noticed the strange smiles on the faces of the two foreign girls.

Astro was very smart, so school was just boring for him, but Horny Tuna was bad in everything except fighting and eating food. Well, if being a pervert could be considered as a skill, then her level would be EX.

While everyone was still panicking, Astro and Kiana felt that there was magical energy in this world. Although it wasn't particularly suitable, they didn't care.

The main character could finally transform into any of his forms, and Kiana could finally fight seriously.

But above all, the couple was curious about what was going on here. Moreover, since they did not have any information, they did not make hasty decisions.

After listening a little, Astro learned that the entire class had been summoned as heroes.

Just think for a second. Two herrschers were summoned as heroes.

"Man, I can only say one thing - you failed the summoning on all possible fronts."

But the protagonist thought about it based on his observations of the class. NO ONE, absolutely no one in this class was suitable for this role.

They were children whom you could manipulate as you please. HEROES couldn't be like that. And heroes couldn't exist, since a coin always had two sides.

For example, any Herrscher could also be considered as the hero of Honkai Will.

In order to not listen to this shit, Astro climbed onto the back of his beloved pervert and fell asleep with a satisfied smile.

Astro spent the next few days in the library, exploring this world, hoping to find at least something. And what he found made his hair stand on end.

The church of this world was a real cult. They were incredibly disgusting, but as a real Herrscher, he didn't care. Would he care about the little people whom he had killed with his own hands by the millions?

Horny Tuna beat all of her classmates in training at the same time.

When the Status Plate was issued to the entire class, the two Herrschers sent Honkai Energy in it. The result was that both plates exploded instantly.

When the girls of the class saw how something exploded in the hands of their beloved little sister, they made such a fuss that the Church had to make concessions and no longer touch the main character.

Let's go back to research. The only place that was not even mentioned in the library were the dungeons. And this seemed suspicious to the main character.

Why did he think so? It's simple - their number was small and it was known that no one EVER passed them.

Also, he found out that the Church was the main force of this world. After he transformed into his bestial form, the natural elementals whispered to him about all the secret deeds that were going on in this world.

Do not forget about the "Angels" who followed the class. Naturally, they were interested in Kiana and Astro, but every time one of them tried to test the souls of our Herrschers, these angels turned into vegetables.

Somewhere, a dark-haired girl tortured the souls of these Angels, who dared to think about harming her beloved Onii-sama.

On the day that Kiana and Astro were about to flee, it was announced that the heroes would go to the first dungeon.

Although the "little girl" did not want to mess with these idiots, the perverted tuna asked him to go with the class.

It was important to note that only those who wanted to go to the dungeon did so. Some didn't have combat classes or simply didn't want to.

Naturally, Astro, who expressed his desire to go, shocked the entire class. Almost the whole class loved him and tried to protect him.

The only plus from this overprotective behavior was that he got any sweets that he asked for.

Going down the dungeon, the main character made a list of those who needed to be killed.

He absolutely didn't care about people, but other races in this world suffered from them.

First on the list was Kouki Amanogawa. Although he was a positive character "in theory", his idiocy would bring a lot of problems.

The next one is Daisuke Hiyama. Astro knew about his plan to assassinate Hajime. Did he want to save him?

Pffff! Funny. This was the reason for the murder.

The last one was Eri Nakamura. From his observations, he was able to figure out that she was obsessed with Kouki, and had already made a pact with the demons to make the "Hero" her own.

How did the protagonist find out all this? Through the power of nature. This world wasn't tainted by technology, so he had almost unlimited power.

Naturally, dungeons were excused from that list, as they were not part of nature, so he had to rely on his strength, which, by the standards of this world, was more than enough.

While the front rows plowed through the monsters, Astro calmly walked behind, listening to music.

But some idiot in front grabbed a trap that moved everyone to the 69th floor.

-Meld-san, we have to retreat! (Shizuku)

But a white spot rushed past her. This white spot turned out to be Kiana, who began to destroy the skeletons.

Many calmed down a bit when they saw how easily the tuna dealt with monsters until it appeared.

Behemoth - for everyone present, it was like a creature straight from hell.

Thanks to the panic, the main character, who had already transformed into his male form, got rid of Eri and Daisuke. Both of them didn't even have time to notice how their hearts were ripped out.

The last thing they saw was an incredibly handsome young man with heterochromatic eyes, who threw them off a cliff.

During this time, Hajime rushed to "help" Kiana. Although his class was not suitable for combat, he was willing to help his classmates as best as he could.

All the others also started helping the tuna, but Behemoth remained the main problem.

At that moment, when the pervert aimed at the main boss, she noticed out of the corner of her eye how someone flew past her with insane speed.

Everyone present saw a tall young man with snow-white hair, a huge red sword in hand, who appeared right in front of the monster.

(image)

With one stroke, he sliced it in half. But that was not the end - immediately after that, a powerful explosion followed, which destroyed the bridge.

Since Hajime was closest, he began to fall into the abyss until someone grabbed his clothes. Looking at his savior, the dark-haired schoolboy saw an incredibly handsome young man with strange eyes, who was holding him with his tail.

After a while, everyone calmed down. Seeing Kiana and Astro just leave, Kouki shouted:

-Wait! Kiana, do you know him? Why are you leaving with him?

As you might have guessed, this hero wannabe wanted himself a tuna.

Astro's face twisted in rage. Before that, he thought about not killing him, but—

Turning to face the class, the protagonist made a gentlemanly smile and said:

-Nice to meet you again, my name is Astro von Brudestud. How does Kiana know me? How could she forget her husband?

Pulling her by the hand, the white-haired boy kissed the girl on the lips.

Kouki began to accuse our hero of being a demon deceiving Kiana. More reasonable members of the squad were able to add the two and two together and realized that Astro and Astra were the same person.

Although it was incredible, seeing the reaction of the girl who was a bit dazed, they concluded that it was possible.

Kouki, lost in his delirium, decided to save his crush from the demon, so he attacked the main character.

It was difficult to call it an attack, rather a random sword swing. He moved so~ slow that it looked like slow motion to Astro.

Armed with an ax that hung on his thigh, the white-haired youth struck a direct blow, which cut the "hero"s head in two.

-Heh.

Leaving the shocked audience, the Ancestor placed Kiana in his arms and jumped into the cliff.

As they fell down, Kiana was able to recover from the kiss. She decided to behave like an adult - to pretend that everything was as it should be.

But the slight redness on her cheeks surrounding her bright smile betrayed the girl's cover.

He landed on the lower floors and pulled out two of tuna's revolvers.

(Images here)

He created them even before the start of the quest to help the white-haired girl regulate her strength.

Almost all of her attacks were too powerful, which, in some cases, was unacceptable.

-Hold it, tuna. And don't break anything here. I'm going to sleep.

With these words, Astro turned into a small black fox and climbed into Kiana's hood.

Having settled down so that his head lay on her shoulder, the main character began to fall asleep.

-Iris, take as many pictures of this cutie as possible. Then we can exchange them for cookies or valuable information

- Yes, Captain Kiana.

This was the last thing the hero heard before falling asleep.

The next moment, the dark fox woke up because someone began to stroke him behind the ears.

-Hey, cutie, it's time to wake up.

-Five more minutes~

-What if I offer cookies?

-COOKIES?

This codeword instantly awakened the fox, who ate the cookie held by Kiana with incredible speed.

After receiving his dose of sugar, the Herrscher asked the other Herrscher what had happened.

She told him that she had walked many floors and got to a door, and since it looked suspicious, decided to wake up the hero.

When the couple opened the door, they saw a huge room with a strange cube in the middle.

Naturally, both sensed a huge monster hiding in the ceiling.

-Help me, please.

Before doing anything, Astro had his Cleaver in his hand, with the help of which he cut the monster on the canvas. The blaze of this attack was so powerful that nothing remained of the scorpion-like being.

(A/N Just to point out, Yue was in prison for a damn bunch of years but didn't know about this monster. Is she a vampire who has failed her night vision or what?)

-Hmmmm, vampire. But you were eliminated many years ago. "Many" by the standards of this world.

The main character immediately identified who this blonde was. To some extent, he was also a vampire, although "blood-sucker" would be a better term.

-...!

The little vampire was shocked, as the incredibly handsome youth, who looked at her with interest, immediately identified her race.

-—How?

Her voice was hoarse but hope still lingered in it. The hope of salvation.

-Please save me. I was betrayed.

-Kk.

With pure brute force, Astro destroyed the cube that fettered the girl.

-What is your name?

-My name is Astro von Brunestud. That girl over there is Kiana. And your name?

-Give me a name, please.

Looking at her, Astro could only sigh heavily.

-Sorry, but no. I can roughly guess why you want it so much; I don't want to take responsibility.

-Let it be Yue.

Inserted the hyperactive Kiana, who, after a month of stagnation, was finally able to have fun in the dungeon.

-Sigh, let it be Yue. But the responsibility is yours, silly tuna.

-Hey, don't call me stupid. I am very smart. How can the Great Kiana be stupid!?

While the two white-haired ones were arguing, the "baby" began to pull the main character by the sleeve.

-Astro, can I drink your blood? I'm hungry.

In response, she received a click.

- Of course not, you are still too small to drink someone's blood directly.

Being a representative of a similar race, the protagonist knew that drinking blood directly amounted to the conclusion of an alliance. That's why you could only drink from someone with whom you were ready to spend your whole life.

- Actually, I'm over three hundred years old. Due to my regeneration, my body remained childish.

Yue said, expecting a shocked reaction from them because 300 years was a huge number.

-Well, as I said, you're too young.

-Wha?

-Yes Yue, you're still a baby. So, wait till you grow up. He, for example, is more than fifty thousand years old.

The vampire froze as if struck by lightning. This strange couple was not that surprised by her age, moreover, they turned out to be several hundred times older.

-W-w-w-what race are you?

-Hmmmm, such a race does not exist here. But the name is True Beast Ancestor. Very roughly speaking - I am a representative of nature. And she's a pervert tuna.

-Tuna… Pervert… Is this some kind of strong race?

-PFFFFFFFFFFF— HAHAHAHAAHAHAHAHH! STRONG RACE. STRONG IN PERVERSION.

When Astro saw what this little girl asked about Kiana with a serious face, he burst into a laugh.

-OI, I AM NOT PERVERT!

-AS IF! AND WHO STARTED DROOLING WHEN SHE SAW ME IN FEMALE FORM!?

-I don't understand what you're saying.

-Fumu, you want to play like that. OK. Iris, it's your time to shine.

-That's right, Master.

A video appeared in the air in which Kiana hugged Astro in his woman form and looked at "her" like she was a chicken leg.

-Guh. Iris, you are a traitor.

-Ara, Miss Kiana, did you really think that I would go against my master?

At this time, Astro gave Yue a tube of blood. Not being an idiot, after he drank blood for the first time, the ancestor stocked up on blood. What was the point in taking the risk?

Although there were no signs of going berserk from lack of blood, he did not intend to check.

The white-haired youth gave her a vial of Reine's blood, as it was the only blood of a "normal" human. Miwa - kitsune; Kiana - Honkai energy in blood, his - an incomprehensible mixture.

When the main character asked his older sister for blood, the latter practically ran to cut her veins. Then he had to take the knife away from her.

Astro also refused the offer to drink blood directly, as it was a serious matter, and Reine was too young.

-Welp, I'm going to sleep.

Said Kiana and climbed in MC's hood.

-Yue are you ready to go? Or do you need to rest?

-I'm ready.

Taking out his weapons, the group went further into the dungeon.

Since Astro did not want to get his hands dirty, he used a composite bow and throwing knives. He heated both knives and arrows with his flame to incredible temperatures, allowing the arrows to pass through the monsters.

On some floors, they encountered fire-resistant monsters. Naturally, the main character could burn them, but such a flame was too powerful.

In this case, he fought with swords or his claws when the monsters' defenses were too powerful.

Thus, the group quickly reached the bottom floor. After waking up the emergency food, they opened the huge doors before them.

-I know, I know. A boss should appear here, with whom we will have to fight and defeat to become real heroes.

Looking at the energetic white-haired girl, Astro smiled. Although he had no memory of her, knowing the realities of the Honkai World, it was a pleasure to see her like this.

-We are following this plan - Kiana and Yue take over the monster that is hiding for a while. Iris and I will be preparing our prototype.

-Aye-aye, Captain!

-Nn. (Yue)

Both of them rushed forward, and Astro began to take out a case with a cannon.

'Master, are you sure? We haven't tested this weapon yet.'

'How can we test it differently? Moreover, there is an ideal target'

'Sigh, I hope everything goes well.'

During the conversation, he took out and loaded the weapon: the Serenity Rifle.

How it worked was simple: Using almost magical technology, this blaster could contain 'Nothingness' in its magazine, having the ability to infuse anything to it to make the 'Nothingness' into 'Something.' The resulting energy will be extremely strong, as 'Nothingness' will clear all the undesired effects while boosting the desired ones. A fire at normal temperature will burn stronger than the sun if the user wants, or give enough light to blind everybody in a kilometer radius.

(E/N: Enough bullshit to make a bull blush in shame, I know.)

(Image here)

It was developed a long time ago, but due to its destructive potential, Astro did not use it.

The only problem was that it wasn't known how it would shoot and what the result would be. Would it shoot, to begin with?

'Set it to medium power. More will be too dangerous'

At this time, two girls fought with Hydra. It would have been a simple foe for Kiana if not for one of the heads that constantly healed the severed ones.

She was about to use Cleaver of Shamash, but she heard Astro scream

-GET OUT FROM THERE! I'M READY!

After making sure that the girls moved back to a safe distance, the main character pulled the trigger.

The bullet reached Hydra instantly. It moved so fast that the destruction that followed the shot did not appear until a couple of seconds later.

What about Hydra? The moment the shot reached the target, it burned out. The monster burned out so quickly that Kiana and Yue did not even have time to understand.

-WOAH! That was so cool, Ast—

But when she turned to the hero, she saw a terrible picture. Astro stood in the center of a small crater that was smoking with temperature. But what terrified the white-haired girl and the blonde was the appearance of the ancestor.

He was completely missing the right side of his torso - there was no arm; all of it was burnt to nothingness. His bones and internal organs were visible.

Although his incredible regeneration kicked in, due to the tremendous temperature and scorched skin, it acted slowly.

-Yes, that was aweso—

Those were the last words he managed to say before passing out. Astro lost consciousness, not from pain shock or injuries, but because Iris forcibly injected him with a crazy amount of medication.

The amount that had to be injected into could kill the population of a large city. His race was, thankfully, incredibly resistant to various types of drugs.

When the effect of the meds ended, Astro woke up from a wild thirst for blood. He acted on instinct so that the target was the white-haired girl who slept with him.

-Hnngh. Astro, I'm not a cookie for you.

Although she feigned displeasure, Kiana was very glad that he woke up. Astro had no memories of anyone yet, but the tuna knew him too well. In every life, he was one of the strongest herrschers, who killed an incredible number of people, but he sacrificed himself for the sake of loved ones each and every single time.

He had a strange personality - he always seemed disinterested in anything other than sweets or science, but Astro was actually insanely calculating.

Since Kiana saw all his memories, she saw how he suffered that he could not change the fate of those close to him.

But what surprised her most was that it didn't break him. Even though all his attempts were useless, Astro repeated this every time.

Tears welled up in her eyes from these thoughts. The white-haired young man immediately noticed this and asked with a bewildered expression

-Kiana, are you okay? Did it hurt? Or did I drink too much blood?

Seeing his worried face, she quickly contacted Iris.

<Click>

-0_0 What was that?

-Heh. You don't often make such a face. Naturally, I'll save it as compromising evidence.

-...IRIS!!!!!! ON WHOSE SIDE ARE YOU?

-<Please forgive me, at the moment Iris is not available, she is undergoing an update>

-IRIS! DAMN IT! I WILL MAKE YOU A BODY IN THE FORM OF A SOFT TOY FOR EVERYONE TO BE TORTURED!!!!

While he was arguing with Iris, who pretended not to work, an aphrodisiac kicked in.

-Hng, Astro

With these words, the white-haired woman threw him onto the bed and began to hug him tightly.

-Forgive me, Astro. You've done so much for us, but I can't even tell you.

-Come on. Although I don't know what you're talking about, I'm sure I didn't do anything like that.

"Sigh. If you only knew how many times I heard this from you. "

-Astro, I love you...

-Heh, perverted tuna, I love you too~

Although he had no memories of her since they were blocked, his feelings could not be hidden. Perhaps he knew her for more than one life, who knew?

Kiana could no longer restrain herself and kissed the main character.

The thing that happened next shouldn't be that hard to guess.

———

E/N: I have no fucking idea why an aphrodisiac kicked in.
