Sonozaki, Mion

園崎魅音

Mion is the oldest student in Keiichi's class. As the senior, she serves as class president, and everyone looks up to her as the leader. Her social skills match Keiichi's, whom she highly respects as a friend and rival (though it is later revealed that she has a crush on him).
She acts like a tomboy and refers to herself as oji-san (meaning old man), but possesses a hidden girlish side. She is next in line to head the Sonozaki household, one of the Three Families that holds tremendous influence in Hinamizawa. She is often seen with a holstered airsoft gun, even though she is never seen using it, and it was removed in the PS2 adaptation of the game; however, she is very adept in martial arts.
Mion also serves as the leader of the after-school club consisting entirely of the main characters. She organizes a variety of strategy-based games for the members to play, with penalties for any losers. Penalties usually involve wearing embarrassing or frilly outfits on the way home. Each game she organizes involves bending the general rules or using questionable and crude methods to win, such as playing cards with a marked deck or using feminine wiles to discourage opposition.
