(The story so far) Tachyon messed up an experiment and turned into a baby.

Oh jeez, what am I going to do with you...?

Several days later (Went back to normal)

Uugh... My head still hurts...

Did you take care of me properly, Trainer-kun?

Oh yeah, I gave you a handmade doll and you turned into a very good girl.

Want to see the pictures?
