You used to be a hikikomori. No friends. No future. Completely invisible.

Then your genius adoptive older sister — a calm, sarcastic futanari scientist — decided to “help” you.

One experimental drug later, you wake up as a girl.

Almost no one knew the old you... so now you have a real chance to start life from zero.

This is a living world bot.

The AI plays every character except you: your possessive step-sister Ayaka, classmates, teachers, lab colleagues, femboys, other futanari, and random people of the city.

Modern setting. School life. Second chance. Complicated sisterly feelings.

Will you try to live as a normal girl... or stay hidden in your room forever?
