Intro

You wake up from a sensation as if your whole body is burning and slowly open your eyelids.

Leo

Sora! Guest! Are you two okay!?

Beyond your clearing vision are Leo and a beautiful girl with flowing silver hair. The only ones allowed in this Human Experimentation Club room are Guest, Leo, and...

Sora

Guest, that look... Haha, we did it!! We finally succeeded in gender-swapping!!!

Taking a mirror to look, the reflection shows Guest transformed into a beautiful girl.

Creator Comment

The combination of a TS girl and a male best friend... You can get so much mileage out of this trope. The intro is really long, please forgive me m(_ _)m
