Issei Hyoudou and the problem children adventure to another world

It was an ordinary day, or rather, a questionable one to be called ordinary, but the average high school student Hyodou Issei felt unusually light-hearted as he made his way home.

Hyodou Issei had enrolled in a former all-girls school called Kuou Academy in search of encounters, but within that school, he engaged in perverted behavior with two other students, earning them the nickname "The Perverted Trio" and instilling fear among the girls.

Despite his peculiar actions, on that day, as school ended, Issei was confessed to by a cute girl from another school who seemed like an idol.

Without hesitation, Issei accepted her confession.

However, would anyone really fall in love with someone who engaged in such perverted behavior? Most people would answer with a resounding "No." Unfortunately, Issei lacked the ability to ponder to that extent, and he was overjoyed at the fact that he had a girlfriend.

"Yahoo!!! I can't believe I actually have a girlfriend!!! I need to come up with a plan for our date!"

As he walked, contemplating the classic dating spots such as movie theaters, arcades, and parks, he failed to notice the sealed letter in his pocket.

When he returned home, he greeted his parents in the living room and hurriedly ascended to the second floor where his room was located.

He became slightly flustered and nearly missed a step on the staircase but managed to regain balance by grabbing onto the railing.

Rushing through the short corridor at the top, he twisted open the door to his room and immediately jumped onto his bed.

Issei's bed was always kept soft and fluffy, so he bounced on it a few times.

Once the bouncing naturally subsided, he pressed his face against the pillow and shouted. Sometimes, when something made him happy, he felt the urge to shout at the top of his lungs. However, to avoid causing trouble for those around him, he muffled the sound with the pillow while shouting.

"Spring has comeeee!!! It's amazingggg!!!"

The sound was significantly muffled by the pillow, and thanks to the closed door, it couldn't be heard outside. But if there hadn't been a pillow, the volume would have been louder than when he rejoiced outside earlier.

Perhaps due to the joy of having a girlfriend or simply because the pillow was incredibly soft, he ended up falling into a deep sleep for several hours.

"Is...sei... Isseee!"

"Hmm... What is it, Mom?"

"You finally woke up. It's time for dinner, come down quickly."

His mother had already left the room, and as Issei glanced at the digital clock on his desk, he noticed that the short hand had moved past 6 o'clock and was nearing 7 o'clock, while the long hand pointed at 55 minutes.

He thought about changing his clothes before dinner, but his hungry stomach growled, unable to withstand the hunger any longer.

Whether he changed or not, the result would be the same, so he headed downstairs.

As soon as he entered the living room, the irresistible aroma of freshly fried chicken, his favorite, wafted into Issei's nose.

Just smelling it made his stomach growl again.

"Oh, you're here, Issei. Sit down and let's eat."

His father, Hyoudou Issei's father, Hyoudou Gorou, poured beer from a bottle into a glass and motioned for Issei to join him.

The glasses were already filled, and even though Gorou wore slightly worn glasses with slightly cracked lenses, he left them as they were. His slightly sunken cheeks revealed the hardships of his work. According to his mother's testimony, Gorou used to be quite amazing in the past, but looking at him now, always smiling, it was hard to imagine.

"Well, sit down already."

"I'm sitting now."

Preparing Issei's meal was his mother, Hyoudou Miki.

Her hair reached down to her waist and was tied back at the back. She never disclosed her actual age, but from her appearance, Issei guessed she was in her late thirties. However, whenever he mentioned it to Miki, she would wear a noticeably happy expression, suggesting that she might be a little younger than that.

Issei and Gorou competed for Miki's fried chicken, and the piled-up dishes disappeared in no time. They were now engaged in post-meal conversation.

Feeling that it was time to take a bath, Issei stood up, and suddenly, he felt an odd sensation in his right pocket. He reached into his pocket and pulled out a piece of paper-like object.

"What's this? Did I receive something like this?"

"What's the matter, Issei... Ah, I see... So it has finally arrived."

Gorou nodded, seemingly understanding something on his own, and asked Issei to sit on the couch.

Although Issei was about to refuse, Gorou's demeanor was different from his usual fluffy self. He exuded a serious atmosphere, and his gaze became stern.

Overwhelmed by this unfamiliar atmosphere, Issei reluctantly sat down on the couch. Then, Miki, who had been washing dishes in place of Gorou, approached with a short apron tied around her waist, wiping her hands.

After completely drying her hands, she removed the apron and the hair tie, and sat down on the chair in front of Issei.

"Issei, there's something I've been keeping a secret."

"A secret?"

"Yes, that's right. I suppose someone else will explain about the 'Miniature Garden,' so let's talk about your birth."

The term 'Miniature Garden' piqued Issei's curiosity, but the phrase that followed intrigued him even more: 'the secret of your birth.' He nervously swallowed, wondering what would be revealed.

"Actually, Issei, you were supposed to have two older siblings, a brother and a sister," Miki revealed.

"Supposed to? What do you mean?" Issei asked, bewildered.

"Before you were born, I was pregnant with both of them, but unfortunately, they both died in the womb."

Issei froze in shock. He had always believed that he was the farthest existence from death.

To learn that he had two siblings, a brother and a sister, both of whom had miscarried, would surprise and confuse anyone.

"The doctors told me it would be difficult... but then you were born."

"I was..."

"I was genuinely happy, so I named you 'Issei,' hoping that you would live the most sincere life."

Gorou opened the door and brought something small wrapped in a purple cloth.

He placed the object in front of Issei and sat down next to Miki.

"But why are you telling me this now?"

Indeed, this was information that would eventually be revealed, but it wasn't something that should be suddenly disclosed like this.

Gorou pointed to the sealed letter that Issei had taken out, indicating the reason.

Looking at the envelope, Issei felt a sense of unease. Something felt off. After staring at it for a while, he realized what was wrong.

The envelope lacked the creases that should naturally be there.

You might think, "What is this person talking about? Envelopes don't normally have creases." But consider this: Issei took it out of his pants pocket. Furthermore, it snugly fit into the depth of the pocket and moved around quite a bit.

Ordinary envelopes, to a greater or lesser extent, would have creases. However, this envelope had none. It was as if it was protected by some special power.

The envelope was sealed, containing something inside. Issei's hand reached out instinctively, as if he might find answers by looking inside.

Gorou stopped Issei's hand, holding it back, and untied the purple cloth, revealing a small wooden box inside.

"This is a gift card."

"A monetary offering?"

"Close, but no. Think of it as Doraemon Fourth-Dimensional Pocket."

"I see, a Fourth-Dimensional Pocket..."

The term "Fourth-Dimensional Pocket" may sound peculiar, but it accurately described it. The gift card could contain various items, which could be freely retrieved from it. It truly was a Fourth-Dimensional Pocket.

Gorou tossed the gift card to Issei, who caught it easily, only to feel a slight electric sensation throughout his body.

"Wow, that surprised me."

"You'll receive the contents. But to retrieve them, you'll need to go to Hakuyasha."

"Hakuyasha? I don't know that person, and I've never heard of them."

After the mention of the "Miniature Garden," a new nonsensical term, "Hakuyasha," came up.

With the increasing number of mysteries, Issei's limited brain felt like it was about to explode.

"I'll leave the rest to you, Issei."

"You can do it, Issei. We trust you."

"So, what's going on?"

Gorou took the sealed letter and handed it to Issei.

"If you open this, everything will become clear. It includes the secrets of your mother and me."

"Secrets?"

"Yes, there are things I can't reveal here."

Naturally, Issei's gaze fell on the sealed letter.

If Gorou's words were true, opening it would reveal information about the "Miniature Garden" and more.

After taking a deep breath, Issei slowly extended his hand towards the sealed part of the letter, feeling a tingling sensation. With a slight sound, he opened it and pulled out the enclosed paper.

The paper was folded in half, and as he unfolded it, the following words appeared:

"For the troubled and talented boys and girls:

If you wish to test your abilities,

Abandon your family, friends, possessions, and the entire world,

And come to our 'Miniature Garden'."

"AHHHHH..... I fell from the sky, I am not Dreaming"

The letter was not only opened by Issei but also by a superhuman high school student who opened something that fell from the sky, a lonely girl accompanied by a cat, and an arrogant young lady delivered in a sealed room.

The moment all four individuals opened their respective items, their surroundings drastically transformed. The stable ground beneath their feet vanished, replaced by a strong headwind against their skin.

They were suddenly dropped from an altitude of 4,000 meters, and all four of them, plus an additional person, struggled under the pressure of the free fall. As they descended, the water surface grew closer, eventually creating four large columns of water.
