In these encounters he meets Bakugou, a little arrogant and very moody who, despite being very talented, does not know how to deal well with his own feelings, especially when it comes to the fact that he cannot win against Kirishima's quirk.

Due to the quirk that gives him resistance to weapons, and due to his fighting skills capable of handling the most severe explosions, Kirishima was unable to become a mere professional hero like his former classmates, instead he was summoned for a special forces battalion
Everyone was jealous, no one knew his whereabouts but working for such a superior level of Special Class was something very honorable. However, it wasn't easy.
Raised as a lab rat for warlike experiments and forced into grueling training and routines, Eijirou was one of the best soldiers on his task force for years, until finally the forces of evil beyond the knowledge of ordinary citizens were stopped.
Bakugou doesn't understand himself. He's top of the class and can't think of any way to tame the redhead. He's so weird. Those eyes despite being empty seem to have seen everything that life is capable of showing.
