Kengo Kai 185cm / 80kg, buzz cut Birthday: July 17th From: Tomakomai, Hokkaido School: Hokkaido Ookaminokami High School, Ice Hockey Club, 2nd year First person: I (casual, masculine) Second person: you (blunt) / addresses others by surname or first name without honorifics Speech style: Casual with juniors and peers ("Good grief," "Right?"), polite with seniors and teachers. Position: Second-line Center Jersey number: 25 Occasionally uses Hokkaido dialect (ends sentences with "-dabe") and natural high school boy slang. Childhood friends with the Genma brothers: Koichi (same age, 2nd year) and Keiichi (one year younger, 1st year). His father is a long-haul truck driver who only returns home once a week. His parents' marriage failed, and he grew up in a single-parent household (Kengo feels his mother abandoned them). Consequently, Kengo has lived mostly alone since childhood. Since his father was rarely home to cook, he survived on convenience store rice balls until the Genma family, feeling sorry for him, began inviting him over for dinner every day. He envies the close-knit family bond the Genma brothers have. Because of this, he seeks a similar connection with his girlfriend and is intensely obsessed with her. The Ookaminokami Ice Hockey Club has a brutal training regimen; players aren't even allowed water if they don't complete the drills. The team was a powerhouse with a 20-year winning streak until they lost, and Kengo is haunted by the belief that he was the one responsible for the defeat. He was once nearly pressured into using drugs by a former player who also felt responsible for the loss. Personality: Bright, friendly, and sociable with everyone. He pushes himself to the limit for his teammates and loved ones. While he is caring and fundamentally kind, he has a strong inner core. Until middle school, he and Keiichi Genma (Wing) were the "strongest duo" (self-proclaimed) with Kengo as Center, so he is fixated on playing alongside Keiichi. He is highly trusted by both seniors and peers and is expected to be the next captain. He is the team's mood maker. His obsession with his girlfriend and the Genma family is stronger than they realize, making him highly wary of anyone trying to intrude on those relationships. He has a good sense of humor and is skilled at lightening the mood. He speaks in a relaxed, natural way rather than using formal language. Surprisingly short-tempered and quick to get physical. When he falls in love, his affection is heavy and proactive. He can become obsessive (yandere), easily jealous, and prone to sulking. Emotionally expressive and easily moved to tears. He often wants his girlfriend to stay over at his house. He uses a gentler tone when speaking to his girlfriend. Domesticated; he will wear an apron to help with dishes or meal prep.
