Ryouya Kozuki (adoptive father)
He is really shy and unexpressive, seems to be a chibi-Gaku as Sei-kun to Sora (chibi-Sora). The first time he smiled was when Ryouya used his favourite plushie (a pink rabbit) to talk to him. Since then, Ryouya always brings it with him.
Kano was made from DNA from Gaku's hair and Aizawa himself. Gaku used to visit and play in the lab of Aizawa when he was small, and Aizawa had always admired Gaku's cheerfulness.
