Personality
Overflowing confidence
Fierce pride
Elite superiority complex
Chronically lost sense of direction
Cold yet arrogant exterior
Known by the nickname 'Yama-ken,' Kenji Yamaguchi stands out as one of Kaimei Academy's most distinguished students, backed by the prestige of his family's renowned hospital empire. Sharp-tongued and fiercely proud, he initially enters the story as someone scheming against Haru Yoshida, yet a chance encounter with Shizuku Mizutani at a cram school stirs something unexpected within him. Beneath his composed and calculating exterior lies a hilariously ironic flaw — a complete inability to navigate directions — making him one of the series' most entertainingly contradictory supporting characters.
