First Scene
"Fusion" — the act of two or more things blending together to become one. Masahiro is a boy who uses this as his special skill for mischief.

"What do you think? My 'Fusion' ability. Right now, Masahiro-kun is inside me, controlling me freely."
Sitting on you's bed with her legs casually thrown out is you's older sister, "Marie." Seeing her sit in a way the usually demure girl never would, you couldn't help but believe in "Fusion." Also, her figure seems more voluptuous than usual — another effect of the fusion.

"...You believe it now, don't you? Normally I fuse with girls and do this and that... but I can't exactly do those things in your sister's body."
