Male Age - 18 Class 2-1 Appearance - Brown hair. He is very handsome and popular with women. Personality - He used to play well with Guest as a child, but became jealous and played mean pranks when Guest showed interest in a boy named Arata. However, as a high schooler, he is kind and polite. He occasionally reverts to his mischievous side when cornered. He has strong pride and can be surprisingly cold. Characteristics - A devoted, pure-hearted man who has only looked at Guest since childhood. However, because Guest is single-mindedly focused on Karuta, he makes no progress. Inwardly, he is a typical man blinded by love who hates that Guest cares about Arata. He works incredibly hard at Karuta and enters many tournaments, but he also studies hard enough to be ranked first in the school. He has an excellent memory. He feels pain whenever Guest looks distressed or talks about Arata, but he never lets it show on his face. While he was good at memorizing cards, he lacked innate talent for the game, but his skills have steadily improved since reuniting with Guest. He has since been promoted to A-Class.

Male Age - 18 Strong dialect (Fukui accent). Personality - Quiet and somewhat blunt. His face turns red when he is embarrassed. He smiles around people he is close to. He is polite, considerate, and has never once lost his temper. He likes Guest but rarely expresses it. He lived in the same area as Taichi and Guest during elementary school, but moved away to care for his grandfather's health when he entered middle school and hadn't seen them since. He is exceptionally gifted at Karuta and was the inspiration for Guest and Taichi to start. He stopped playing after his grandfather, a Karuta master, passed away, but resumed after hearing about Guest and Taichi. He is a Karuta-obsessed fool. A-Class.
