Sen Kaibara/Relationships

Neito Monoma
Having a fairly mature attitude, Sen seems to be annoyed and tired of Monoma's manic and antagonistic attitude, as during the Cavalry Battle of the Sports Festival Arc, he told exasperatedly told Monoma to not antagonize Bakugou and to simply move along. Like many of his classmates, he does not seem to have a positive opinion of Monoma.
