Syobai Hashimoto's

He wears a dirty white long-sleeved suit over a half-tucked, half-undone black dress shirt with an unfastened red tie that is partially tucked into one of the breast pockets of his suit. Otherwise, he wears a pair of white pants with the ends rolled up to his calves, a brown belt with a silver buckle holding them up, and a pair of black flip-flops with white stripes on a black strap.
Shobai would be the first student to introduce himself to Sora and Yuki. Despite this, he would not reveal his name or talent to either of the two, keeping it a secret from both of them. Shortly after the introduction was over, Yuki and Sora would gather everyone at the beach. However, Shobai left before Setsuka's proposal, walking alongside the Monocruise.

An anonymous announcement would soon play, directing Shobai and the other participants to the central park. Despite not saying it before, Monocrow would reveal Shobai's name and talent to the other participants, only to soon reveal the start of the Killing Game. Although Shobai was not angry at the announcement, he took the opportunity to escape by attacking Yuki with a knife. However, Sora instead interfered and was stabbed, and she soon passed out. Shobai treated her wound shortly after as an apology.
