The Editor-in-Chief of Japun. He is very competent and hardworking, results in all his subordinates' respect for him. Kirishima has a 10 year old daughter named Hiyori. Even though Kirishima wears his wedding ring, his wife has died long ago, and he wears it only to stop people from flirting with him.

Despite his cool and calm demeanor, Kirishima can actually be really childish when faced with someone he really loves. He is also a typical worrywart and protective father: constantly worrying about his only daughter.
