It’s been a few years since I left my hometown where I was born and raised due to my father’s work.
Waiting for the protagonist, who returned to the town where he was born and raised, was his childhood friend Miyuki, who changed from a boy to a daughter.
Miyuki, who used to call him “Nini” and looked up to him, wondered where and how he went wrong, and now calls him Zako.
Surprised, but when the main character tells him not to call him Zako, Miyuki smiles mischievously and lustfully, telling him to try to make him do that.
For the time being, sleep there――
The main character is puzzled by Miyuki’s words and expects.
Miyuki smiled as if she saw through it and put her face to his crotch.

Hasegawa Nozuomu, the main character, will come to Shiraki Gakuen as a new teacher. After being appointed, the hero is told from the principle, "Our students are all special people and shouldn't interfere or hold them back" Nozuomu not completely understanding cryptic message soon finds out how special and different students are at academy.

Protagonist Shun was a 2nd year student. He was an average teenage boy, still not interested in girls. Everything changed with the arrival of transfer student Ei.

One day Shun followed Ei to a remote part of the school he never knew about, an underground passage. Ei disappeared inside, then appeared in front of Shun wearing girls clothes.

This was a feast, an orgy of all male students dressed as charming girls. As the perversion unfurled before his eyes, Shun felt his own lust stir...

When the part was over Shun stood alone, sighing in the night that would never feel normal again. His head still spun from what he had experienced.
Guided by Ei's hentai hand, confused about his own aroused feelings, Shun didn't know what to do. The next day he had to talk with Ei. School could wait.

Me and my mother lived in a two-person apartment.
Everything was fine, we weren't rich but it was comfortable.
My father had died when I was young, leaving mom to
raise me. She had her own aspirations, but always put
me first.

Elegant, tender and generous. Very beautiful. I was proud of my mother.
She was mine and mine alone... or so I thought...

Little by little, our happy life began to crumble...

It's all the fault of a classmate I hate... Kazuya Eguchi.

He was shameless, crass, violent...
Everything that was mine, everything I cared about, he destroyed...
That son of a bitch never thought about anyone but himself...
He treated women like disposable sex objects...

The most unforgivable thing is he did it with my mom...
