The School is Under Hypnosis, and I'm the Only One Who Knows (I Was Able To Send The Hypnotist Flying Back Home, but Now I’ve Got The Whole School Under My Hands As My Harem, What Should I Do!?)

Chapter 4: My Sister and Our Home

I have no money. I have no home.

Where did my parents and Tanaka go? What should I do about this harem school? There are many things I need to consider, but before that, I need to figure out how to survive my current predicament.

I don’t have enough money to stay at a manga cafe or spend the night at a karaoke place. My close friend has been replaced by a beautiful female student, so I can’t stay at their house. I might have to sleep on a rough concrete floor… But what about food?

With nowhere to go, I aimlessly wandered around the school building, killing time. Then, a cute, short girl with large breasts ran towards me, her chest bouncing with each step.

Hey, you should stop running in that short uniform because your breasts might fall out. I thought to myself, but my gaze was fixed on her bouncing breasts and the dangerously short skirt that looks like it might flip up at any moment.

A girl with a childlike face and disproportionately large breasts hugged me. Her huge breasts pressed against my stomach.

“Onii-chan! Where were you yesterday? I was looking for you!”

O-Onii-chan!? I don’t have a cute, busty little sister like this! I don’t even have any siblings! Most of the strange events in this school are probably Tanaka’s doing. This girl must also be under some kind of hypnosis from Tanaka.

“Huh? Uhm, lil sis, can you let go of me?”

“Mika.”

“Huh?”

“Call me Mika.”

“Uh, Mika-chan, can you let go of me, please?”

“The ‘chan’ isn’t necessary!”

“Mika, let go of me.”

“Don’t want to!”

Eh… Wasn’t the flow of the conversation as if if I called her name, she would let me go?

“If I let go, you might leave again, Onii-chan! Let’s go home together, okay?”

“Home? Where?”

“Mou~! Of course, our home!”

Mika, who claims to be my sister, pulls me, leading me somewhere. Since I had nowhere to go home to, I decided to follow her.

Mika and I arrived at a tower mansion. She entered the password at the entrance and went inside. The chandelier in the entrance hall shone brilliantly, and there was a concierge, indicating that this was a high-class mansion.

Mika left the entrance and got into the elevator, pressing the button for the top floor.

It seems like Mika lives on the top floor of this tower mansion. She has a key, so there’s no doubt about it. It’s natural for her to enter her own home, but I cautiously followed her. I was quite nervous about entering such a luxurious mansion.

“E-Excuse me for intruding.”

“Onii-chan! It’s not ‘excuse me for intruding,’ it’s ‘I’m home’!”

“I-I’m home.”

Mika corrected me, and I repeated her words. Still, Mika seems to believe that this is our home, both mine and hers, why? It might be because of Tanaka’s influence as well.

Tanaka probably used hypnosis to make this place his and Mika’s home. But for some reason, it has become our home, mine and Mika’s. I assume that’s what happened.

What kind of hypnotism did Tanaka use on Mika? If he hypnotized her into thinking she was Ichirou Tanaka’s sister, then she shouldn’t have mistakenly believed she was my sister. Even now, it would be strange if she didn’t still think she was Tanaka’s sister.

Did Tanaka hypnotize her to believe she was a male student’s sister at Sakura Minami Academy? Why would he use such strange hypnosis? Or did he use hypnosis on her to believe she was Ichiro’s sister, without specifying the full name? Coincidentally, my first name is also Ichiro.

I don’t know. If Tanaka had hypnotized her to believe she was his sister, she wouldn’t have mistaken me for her brother.

Does Tanaka’s hypnosis have some limitations? Or did he put her under hypnosis without much thought, and I just happened to fit the conditions that he placed? I don’t know, but I’ll gratefully live in this luxurious mansion with Mika. I have no money, and I can’t keep sleeping on rough concrete forever.

I felt a bit guilty, but I decided to stay in this house until the hypnosis wore off. I explored the house and found a room with a large bookshelf. Tanaka probably intended to use this as his room. The bookshelf was filled with books about hypnosis.

Did Tanaka collect these books? Perhaps he read these books to learn about hypnosis and acquired his seemingly cheat abilities. Maybe there’s a clue here to break the hypnosis. If I have time, I should read as many of these books as possible.

The hypnotism books on the shelves didn’t just contain explanations of the technique. There were also erotic novels, hentai manga, and doujinshi that used hypnotism as a theme. It looked like he had collected anything remotely related to hypnosis.

…

Tanaka might have gathered these books to get ideas on how to misuse his abilities.
