Perfect Affection Plan: Cassiopeia

In an underground location, there is a secret research facility.
During the process of researching biotechnology to advance human evolution, a pink life form was accidentally created.
As a lab report of groundbreaking progress in research, the researchers named the life form 'PCP-Singularity'.
Without thinking if the life form has self-awareness, the researchers subjected it to various irrational experiments.
The life form has been through a series of stimuli, so its instinct of surviving and reproduction has been strongly activated.
It morph into a terrified form, taking revenge on the researchers for what they did, and escaping from the reserch facility!

Surrounded by the blue sea and green mountains, the protagonist moved there.
For him, who has been struggling with the competitive society of the city, this is not a place to retreat, but a new battlefield.

――It was supposed to be.

But, there was no such thing.
From the first day at his new school, he is taken out by his classmates, enjoying what they do, and being inspired by them.

Meanwhile, the three girls that the protagonist met also changed him again: a bright and lively kouhai who has a shocking encounter, Amahara Kogane; a shrine maiden senpai who looks out of this world but is surprisingly mischievous, Kaminashi Yashiro; a tsundere girl and daughter of the landlord who takes care of the protagonist, Ainokura Kazuha.

In the vividness of summer, the love that is born between them will eventually turns into a deep love.

Friendship and love are interwoven.
A love story that only students can tell begins.

We are a family of five, with three daughters and both parents still alive. We live in a detached house not far from the station, and except for the fact that our father is away working away from home, we are a picture-perfect happy family. That is the Sera family.

A young man named Shuchi Izamori inherited a vast fortune. In his unfamiliar home, there was a young and enchanting stepmother, as well as a recently hired beautiful maid. Both aim to capture Izamori’s wealth, intending to seduce the inexperienced young man and make him obedient by setting up lewd traps. Outside the house, additional threats are also targeting him.

Our protagonist is a dull, 30-year-old virgin amateur.
He spends his days surfing the web and envying those who achieve success through news articles.
Suddenly, he is transported to a mysterious page and is enveloped in light...

He opens his eyes and finds himself in a place resembling an izakaya, bustling with people in old-fashioned Western clothing.

After speaking with the receptionist, he discovers he has been transported to a fantasy world where monsters roam.

To make matters worse, the protagonist has been granted the ability to cheat others, allowing him to control them at will.

Using his cheat powers, he successfully forces himself into a hero's party full of beautiful women.

He then hatches a plan to ruin the lives of these beautiful women...
