Hyouka Midarezaki

乱崎 雹霞, Black Thirteen

The three-year-old 'youngest son' of the Midarezaki family. He is a biological weapon that bears the name of 'The Black Thirteenth' (黒の十三番, Kuro no Jyūsanban?). Three years ago, he destroyed the labratory where he was made and ran away, and it seems that he is currently suppressing his past memories. He likes to watch TV.
