Tsuyoshi Ohki  

, 大木剛

Tsuyoshi is Akitos best friend despite their contrasting personalities. While Tsuyoshi is cheerful, honest and kind-hearted, Akito's behavior is perceived negatively by everyone around him. Despite this, both of them share a tough family situation as their parents are divorcing. Unlike Akito, who struggles with his problems, Tsuyoshi becomes more compassionate towards others. His ability to remain strong while facing adversity allows him to recognize the good in Akito and try to convince others that he is not an evil person but misunderstood. However, it's important to note that Tsuyoshi can be quite explosive when someone speaks ill of his family, particularly his mother.
