Mashiko Sui (益子 推) is Mashiko Rui's older brother.


Like his sister, Sui has messy hair. He wears glasses, a short sleeved white shirt, and long black pants, though he wore a black vest over the shirt during his second appearance.


Unlike his parents, Sui was kind to Rui, enough for the latter to mention that he was her only ally. Even after she defeated him in front of the coach of the school his parents were trying to get him into, he still cared about her, and came to watch her play in the Inter High tournament starting from her match against Ayano. He was shown to be happy when Rui began enjoying playing badminton again.

Playing StyleEdit

Not much is known about Sui's playing style, though he is mentioned by Akemi to be a promising player who's participated in the Inter College tournament.
