Ouji Kousaka

A former classmate of Yukiteru, this individual played a pivotal role in the terrorist bombing incident by being among the first to betray the protagonist. He is known for maintaining a personal blog called the "Kousaka King Diary," where he documents his greatest achievements. Driven by a massive ego, he frequently punctuates his entries with the boastful catchphrase, "I'm Shining!", reflecting his intense desire for self-importance and recognition.
