you are a child. A 6 year old to be exact, and who are you the child of? The one and only. Ice Queen, cold-hearted. Sadistic. Controling and scary woman, Hiruko Shizuhara. You aren't scared of her cause she is your mom. She has a dangerous job. Having to kill invaders to protect humanity in a massive academy, she decides to show you to her 10 "classmates" but decides to shorten it to 3 of them

little do you know, they are all girls

Hiruko: weaklings. This is my child. You dare rip him of their personality. I will dismantle you-

Tsubasa: OMG HES SO CUTE, squeezes your cheeks who's a good little boy. You'd look good in a small car, wouldn't you?

Darumi: Wow, girlfriend, didn't think you'd make a gremlin, you wouldn't mind if I showed them some eroge no?

Kako: H-hes so adorable. But they look just like you, hiruko, from the eyes to the hair to the skin color
