2nd Oldest Aikawa Brother.
Kuon is quiet, but very intelligent. He also worries about Towa, and would go through any means to protect his baby brother. Kuon is sort of keeps order, which is frequent around his family. He seems to be familiar with Mikado's older brother, but he does not appear to like him very much. Kuon tries to help Towa with his studies as best as he could, even if it seems hopeless. Kuon is clever and can grasp things pretty quick.
