The Editor-in-Chief of Japun, Kirishima is highly competent and diligent, earning the respect of all his subordinates. He has a ten-year-old daughter named Hiyori. Although Kirishima wears his wedding ring, his wife passed away long ago; he keeps it on merely to deter unwanted advances.
Unbeknownst to everyone, Kirishima has always kept an eye on Yokozawa, admiring his hard work. After Yokozawa suffers heartbreak due to Takano's rejection, Kirishima enters his life. Circumstances bring them closer, despite Yokozawa's initial reluctance. Kirishima assures him that he doesn't need to forget his love for Takano and promises to accept Yokozawa wholeheartedly. These words resonate with Yokozawa, leading them to start dating.
Beneath his cool and calm exterior, Kirishima can be surprisingly childish when dealing with someone he truly loves. Additionally, as a typical worrywart and protective father, he constantly frets over his only daughter.
