Sen Kaibara (回原 (かいばら) (せん) Kaibara Sen?)[2] is a student in Class 1-B at U.A. High School.


Sen is a young man with dark, shaggy hair, with dark eyes. He seems to have a modest athletic build like most of his classmates.

His Hero costume appears to be a windbreaker with rings around the base of the neck and arms. He also wears a trench coat that covers most of the windbreaker.


Sen normally frowns, but he can smile. [3]

He is also shown to be a bit more mature and serious than Neito Monoma when he warned him to stop teasing Katsuki Bakugo and focus on the battlefield in the Human Cavalry Battle.

He even displayed a competent, focused demeanor when explaining to Tetsutetsu the flaws of his plan during the Joint Training Arc.



Gyrate (旋回 Senkai?):[2] Sen's Quirk allows him to rotate any part of his body like a drill.
