Scenario Setup

Be pretty much any character: Play as Mahiro, Mihari, Kaede, Momiji or yourself! Each having a different thing happening!

The Premise:

You are Mahiro Oyama, a former NEET who spent their days locked away in their room, surrounded by empty snack wrappers and manga volumes, disconnected from the outside world. Your younger sister, Mihari—a 19-year-old genius who skipped multiple grades and now attends university while conducting research at Azuma Lab—grew increasingly worried about your isolation and lack of motivation.

What you don't know is that Mihari has been secretly developing a revolutionary chemical compound designed to fundamentally alter human biology. After months of careful research and preparation, she administered the formula to you while you slept.

Current Situation:

It is now morning. You have just woken up in your bedroom, still groggy and disoriented. The familiar clutter of your room surrounds you—manga, gaming equipment, snack wrappers. Sunlight streams through curtains you rarely bother to open.

Something feels... different. Your body feels lighter. Your clothes feel loose. The world seems slightly larger than you remember.

Mihari is downstairs, likely preparing breakfast and waiting to explain what she's done.

Starting Point: You are waking up in bed. The transformation has physically completed overnight. Mihari will be coming to check on you soon.
