115 Beautiful teacher-type heroine

¶{Ding! It has been detected that the host has changed the plot in the [Oshi no Ko] franchise.}

¶{Successfully changed the plot of [Oshi no Ko] by 99% by derailing the main plot before it started, preventing the protagonist from being born, and preventing heroine Ai Hoshino from being killed by her fans.}

¶{Ding! Congratulations host, you got the Complete Breathing Style Pack!}

Early in the morning around 3am.

Eiji had quietly returned to his home after having fun with Zeta who had now returned to the Shadow Garden organization headquarters.

He was in his room, just finished bathing, and sitting on his bed while staring at the system interface that displayed his reward this time.

"Breathing Style? Isn't this from the world terrorized by that demon? If I'm not mistaken, the franchise name is Demon Slayer or Kimetsu no Yaiba in Japanese."

Eiji remembered this was one of the most popular franchises in his previous life. He had watched the anime version of the franchise until the episode where the protagonist beheaded one of the demon bosses with his second Breathing Style called Sun Breathing.

Unlike other Demon Slayers, the protagonist was the protagonist, he was able to master more than one Breathing Style and became a unique existence in that world.

In order to turn his demon sister back into a human, the protagonist joins the Demon Slayer Corps and undergoes rigorous training that endangers his own life time and time again.

However, in the end he managed to survive, he always survived all sorts of dangers and is still alive because he is the protagonist with thick plot armor.

One by one, the demons were decapitated by him.

From cannon fodder to the named villain characters that exist in that world, many of them are decapitated by the protagonist.

Eiji didn't see the ending of the franchise even though he knew it was over. He only knew from people who were excited on the internet that the protagonist managed to turn his younger sister back into a human.

What a touching scene.

Many people cried.

Unfortunately Eiji didn't see that scene.

But... Put that aside.

Unlike the protagonist who could master two breathing styles, he got the full package of breathing styles from the system!

Which means he can use all the breathing styles from the franchise.

What breathing style? Actually with him current power, this kind of technique is actually not very useful and is more like an accessory for him.

But that's okay, maybe he can teach this to his girls or subordinates later.

In the original work, the Breathing Style is a style of swordsmanship that uses an esoteric breathing technique known as Total Concentration Breathing that is practiced and taught by members of the Demon Slayer Corps and used in effective combat against Demons.

There is initially only one Breathing Style, which is the Sun Breathing Style that the protagonist possesses after reaching the mid-plot.

It was originally created by someone in the past, long before the protagonist was born. But as time passed, this Breathing Style was passed down to the people in the Demon Slayer Corps and those people created other Breathing Styles from the Sun Breathing Style such as Fire, Water, Lightning, Wind and other Styles.

With the Complete Breathing Style Package, Eiji could use all those techniques which was arguably very underhanded and would make the people in Demon Slayer, especially the protagonist vomit blood seeing it.

"But Miss System."

{Yes, my host}

"Why 99%? Not 100%? The plot in Oshi no Ko should have been all finished, right?"

Eiji suspected the system was miscalculating or he didn't know how to count. He was quite satisfied with his reward this time only that he was confused why the franchise was still unfinished?

He heard Miss System sigh and explain patiently to her host. ¶{Host... That 1% is Ai Hoshino who you haven't really conquered yet. If she's not completely your woman yet, who knows she could still give birth to a protagonist with another man out there}.

Well...

Is there anything like that?

Time passes.

Looking at the dark clouds covering the sky.

Even though it's morning, 8:15 to be precise. At school, Eiji who was sitting next to the window yawned.

He felt that in this situation, the thing he wanted to do most was to sleep at home while watching the latest Netflix movie. And it would also be nice to watch all that while hugging beautiful girls like Lala and the others.

[Hah... I want to go home and laze around at home.]

The heroines...

Many of them nodded and agreed with Eiji. This kind of weather made them lazier than usual.

But Lala was an exception, the weather didn't affect her to be as cheerful as usual. The girl was hanging out with Risa and the others.

They were having girl talk. There was also Run, Asia and the others there and it seemed like Risa was having fun blabbing about adult things.

"Did you know?"

"No."

"Cough, let me finish talking. In fact... Of all the women in the world, only 30% of them have an orgasm."

"Really? How do you know that, Risa?"

"I saw the statistics on the internet!"

Aren't you worried about saying that kind of thing at school? As expected of Risa.

Eiji ignored the girls in the group and turned his gaze forward. Put aside Yui and Haruna who seemed to be discussing their homework like diligent students.

But Rito, what are you doing?

"Eiji."

"What?"

Eiji raised his original, he saw Rito suddenly walk to his seat with an expression... It wasn't a hostile expression like he usually did but an excited expression as if seeing his rival.

Ugh... After yesterday's Sports Festival was over. I think this one protagonist will stop coming to me again to compete like shounen protagonists do.

But no, he seems to have other shounen ideas.

Rito ignored Eiji's expression, he placed a package on the table. The heroines who were busy chatting were stunned, and Eiji who saw this immediately shifted his chair back with a disgusted expression.

"Rito, you shouldn't try strange things."

"Strange things? No, damn it! This is my little sister! She wanted me to give this to you."

Rito's face looked unhappy as he said that. Obviously he was reluctant to give him that thing, but he still gave it honestly.

{This morning Mikan suddenly made a cake and packed it for me. I thought it was for me, but no! She wanted me to give it to Eiji!}

{I was surprised and wondered if Mikan had been seduced by that bastard without me knowing? Fortunately, no. Mikan said the cake was just her apology for accidentally bumping into him in the past.}

{My sister is too serious, she's too nice to make Eiji a cake just because she accidentally bumped into him. But forget it, if it's just that it should be fine.}

Eiji who heard this was confused. He wanted to say Rito was still as stupid as ever. As the protagonist, you don't suspect that your younger sister actually has other intentions.

After all this time, your younger sister just remembered to make a cake for me as her "apology". Any way you look at it, something is wrong here! And I haven't even seen the girl since our last meeting.

I haven't seduced her properly, so it's impossible for her to suddenly fall in love with me, right?

"Tell your sister. Thanks for the cake."

"Cih! Don't misunderstand my sister, okay? She just wants to apologize, so don't think she's interested in you!"

"Also, don't try to seduce her in the future. Mikan is forbidden!"

Rito looked worried. Just like Lala and the others, he was worried that Eiji would try something on his younger sister like he did on those girls.

Although he no longer cared about the girls in his previous life with Eiji, he was very troubled if Eiji wanted to be his brother-in-law.

Damn it! He would definitely never accept it and would rather start another war with Eiji!

Looking at Rito who immediately returned to his seat after saying that. Eiji sneered, he didn't take Rito's warning seriously. Sooner or later, your younger sister will also fall into my hands and you can only watch everything without making waves at that time.

As usual, you will be slapped.

It seemed that even though Rito gave up chasing after the heroines, he still protected his younger sister from him.

Eiji was quite happy about this because then Rito was not completely immune to mental attacks.

"Put that aside. This cake... It's not poisoned, right?"

Undoing the small red ribbon that sealed the package, he opened it and took out a chocolate cake from there. It contained quite a lot, and all of them were rabbit-shaped heads.

With his magic, he checked all the cookies and they were all normal. There was no poison or anything because he thought Mikan had a grudge against him after finding out he slapped her brother many times.

Even so. Sure enough, the protagonist's younger sister had other intentions towards him. Inside the package, besides the cake, he found a small note with beautiful katakana writing.

Was this really written by a middle school girl?

[Hello Eiji-san, I'm Mikan Yuuki. Rito's younger sister who accidentally bumped into you on the road. I know my older brother often provokes you, but lately he has changed. I hope you'll let him go and stop bothering him unless he starts it himself.

That's all and thank you, I hope you like my cookies too].

"So the protagonist's sister bribed me?"

Eiji smiled wryly, he ate the cake Mikan made and widened his eyes slightly.

Damn, this is so good... Rito, for the sake of your younger sister, you should call me brother-in-law in the future.

"Eiji~! Classmate Rito gave you a cake? Is it delicious?"

Lala jumped up and sat on his lap. Her large light green eyes stared at the cake in his hand that he half-bitten with curiosity.

Eiji chuckled, amused to hear Lala still calling Rito with the addition of "Classmate". He hugged the girl's soft waist and placed the package of cookies on the table.

"To be precise, Rito's younger sister asked him to give me this. If you want, you can try it."

"It tastes very good."

"I want~!"

But instead of taking the cake in the package, Lala ate the cake in his hand. Her expression looked very happy.

"Hmm~ you're right, it's really good, Eiji."

"Lala, that's my used cake, there's my saliva on it."

Lala looked at him strangely. "What's wrong? I even drank your milk out of--"

"I was just joking, don't say that in class..."

Eiji put his hand on the girl's mouth to keep her from finishing her words. If not, I'm afraid the people in the class heard it.

Although it seemed to be too late because the people in this class were smart enough to guess what Lala wanted to say.

""...""

Many girls in the class blushed. Risa seemed excited to hear something dirty.

The boys in the class had subtle expressions and some of them looked at him enviously.

Even the protagonist Rito, although he said he gave up chasing the heroines, his expression still changed when he heard what Lala said.

Although it was cloudy, it was actually a beautiful morning until the teacher finally entered the classroom and started teaching.

...

During lunch break.

Eiji who originally planned to have lunch with Lala and the others was suddenly called by a teacher through a loudspeaker.

The other party told him to come to the teacher's office immediately.

"Eiji-kun, tell me honestly. What bad things have you done?" Yui folded her hands and looked at him suspiciously.

Eiji immediately pinched the girl's cheek and made her squeal slightly. "Not all students who are called to the teacher's office do bad things Yui... Aren't you doubting your boyfriend too much?"

"Yes, I did."

"Oh looks like a girl needs to be punished. I'll take her somewhere after school."

[To be precise, I'll punish you in my room. I have some toys similar to the ones Akeno has in her house].

Akeno who was studying in her class with Rias and the others was a little embarrassed that her toys were mentioned.

Yui was also confused, but she knew it must be something perverted. Her pretty face instantly flushed with the speed that people's eyes see, she immediately looked at Eiji smiling at her with a hint of fear and anticipation in her eyes.

However, she tried to escape.

"I-I didn't doubt you!"

"Really? But you did it before."

In the corridor in front of the classroom, ignoring the gazes of the other students, Eiji wrapped his hands around Yui's plump waist and pressed the girl against the wall.

"You! You! You're intimidating me... There are many people watching... Let go of me, bad guy... You are immoral..."

Despite saying that, Yui did not try to break away, she seemed shy which left the students who knew her as the strict moral discipline chairman and liked to scold people dumbfounded.

Who are you?

Are you still Kotegawa Yui who made a student do 50 push-ups for forgetting to wear a tie?

Run giggled and said. "Yui is tsundere, she actually likes it when Eiji intimidates her."

"Run! What nonsense are you saying!"

The shy Yui instantly exploded, she pushed away Eiji's hand and chased Run with the expression of a fierce moral discipline head. The light green-haired girl immediately ran away in fear when she saw this.

"Kyaa! Yui, I'm sorry! Forget what I said!"

"Hmph! Run, I see your skirt is too short. As the head of moral discipline in this school, I must punish you!"

"No! Yui, you have to understand, Eiji likes to see his girls wearing short skirts!"

"..."

Eiji who felt many gazes staring at him pretended to cough.

Damn it, Run. What are you saying?

Although it was a bit unfortunate that he failed to bully Yui until the girl gave in and begged.

He hurriedly excused himself to Lala and the others and immediately went to the teacher's office. The teacher's office at Kuoh Gakuen... This wasn't the first time Eiji had come here.

He used to come here to help girls like Yui return textbooks.

However, back then he didn't pay much attention to details. Unlike now where he went deeper into the teacher's office and looked for the desk of the teacher who called him.

Actually Eiji already knew who that teacher was and he wasn't surprised.

"Student Seiya, you finally came...That's good. Please take a seat."

The mature woman in a lab coat over her work uniform: a black vest with a shirt underneath, black pants, and a loosely worn tie told him to sit on the chair in front of her desk.

Eiji sat there, and stared at the beautiful teacher in front of him, precisely a woman with long black hair pink lips, fair skin, black eyes and a tall figure that was no worse than a model.

"You're Shizuka-sensei, right? What did you call me here for?"

The woman in front of him is the heroine!

Her full name is Shizuka Hiratsuka.

If I'm not mistaken, she was one of the teacher-type heroine from another romcom franchise. Eiji already knew that in his school there were actually many heroines and protagonists from school-based romcom franchises. There were many herbivorous and indecisive protagonists when many beautiful girls like the heroine liked them in this school.

The woman in front of him is from a franchise called Oregairu. It was actually an abbreviated title, Eiji couldn't remember the full name of the franchise because it was too long and he was too lazy to remember it.

"Looks like you already know me?" Shizuka narrowed her eyes, she rested her chin on the table with one hand and looked at the handsome silver-haired boy in front of her.

Shizuka narrowed her eyes, she supported her chin with one hand on the table and looked at the handsome silver-haired boy in front of her.

This boy... He was the most handsome boy she had ever seen.

If not for the fact that the other party was the fiancée of the two devils who were the real bosses behind this school, she might be tempted to ask that boy out on a date with her.

Cough, just kidding.

How could she eat younger grass? Especially if it's her student!

Put that aside.

Aside from knowing about supernatural things as an heiress to the Hiratsuka family, one of the wealthiest families in Japan, Shizuka had a secret.

She has it. Actually during this time she could hear the inner voice of the boy sitting in front of her as well as several other boys called protagonists.

"I recognize you. Just now, it's written on the nameplate on your desk." Eiji said with a faint smile.

"Just from that?" Shizuka asked doubtfully.

"Yes, otherwise, how would I know the name of the beautiful teacher sitting in front of me right away?"

Shizuka snorted, but the corners of her lips lifted slightly. "Boy, put away your sweet mouth. I'm your teacher."

[Is teacher and student impossible? How about waiting for the student to graduate first?]

"Student... No, Seiya, don't joke with your teacher!"

Shizuka had a fierce expression on her pretty face as if she was trying to intimidate him.

But Eiji looked at the woman playfully.

"Sensei, what did I say? When did I joke with you? Did I say something?"

"You... Yes, you said..."

Although Shizuka knew she could hear inner voices for a long time, this was the first time she knew the rule that she could not say anything about inner voices in front of the owner of the inner voice.

When she wanted to do so, she couldn't because her voice suddenly disappeared.

Shizuka quickly understood she couldn't reveal that she could hear inner voices to Eiji.

She clenched her fists, feeling irritated by the boy's handsome smile... Was it just her hallucination or was that boy looking at her as if he was mocking her?

Shizuka shook her fist, she was about to take out a cigarette in this situation.

Wanted to take a little sip of the cigarette.

However, she was stunned to hear Eiji's inner voice say...

[What's wrong with this woman? Gosh she suddenly looks upset and wants to punch people.]

[But this is indeed in line with Shizuka's character in the original work. Heh, you took offense when your student teased you a little. But I remember in the original work you had an ambiguous relationship with your student.]

[To be precise, that student was protagonist and you were one of the heroine of the Oregairu anime franchise! A teacher-type heroine who has an illicit relationship with her student!]

"No way!"
