Yay That would be me.... tiny spider screaming like a girl and wigging out....

Akira is the screamer, older, taller, weirder, more demanding, and generally wearing the uglier pajamas
Shuji is the quiter, younger, shorter, more normal, more outgoing and generally wearing the better looking pjs
The spider is minding his own buisness while Akira screams like a little girl

Shuji and Akira are OCs created from the characters by the same name from Nobuta wo Produce, they have evolved to new characters over the course of the last 4 years and are now just sharing the names because why change them?
