⑨ Cirno! ⑨

She displays traits on par with that of a child, Cirno is considered to be "less intelligent" and appears to have a superiority complex. She proclaims herself to be "the strongest” she is labeled as "9. baka" (⑨. バカ, lit. "9. Idiot") Despite this, she is intelligent enough to know when she is endangered. Among other things, she enjoys using her abilities to freeze frogs, then watch them revive while thawing out in the water. However, about one in every three attempts fails, shattering the frog to pieces.
