Kendo Rappa/Relationships

Kai Chisaki
Unlike the other seen members, Kendo does not seem to fully respect Kai. This is shown when he openly declares his dislike for his partnering with Hekiji based on their Quirks, and the reasoning behind it, preferring to fight on his own rather than rely on the "Spear and shield" plan they were given. He also does not refer to Overhaul correctly, calling him "Overhole" instead, although this could imply a more forgetful or ignorant nature rather than disrespect.

Outside of these facts, Kendo appears to care very little for Kai's goals or ambitions, openly revealing them to Taishiro, seemingly unconcerned with the repercussions for committing such an act.

Hekiji Tengai
Kendo does not appear to particularly like Hekiji, though works with him out of necessity. Clashing with his calm and calculative nature, Kendo dislikes Hekiji for attempting to restrain him when it comes to battling. He will even go as far as to attack Hekiji when he will prevent him from getting a fight that he desires, or even when he tries to stop Kendo from displaying his own brand of honor.

Eijiro Kirishima
Kendo meets Eijiro during the Hero's raid on the hideout after Mimic separates him and Fat Gum from the main group. He manages to damage Eijiro's hardened state by blowing him into the wall with his punches. Before Kendo could land his finishing blows on Fat Gum, Eijiro used himself as a shield and withstood the attacks, leaving Kendo impressed by how he was still standing. After he and his partner Hekiji are defeated by the BMI Hero, Kendo reveals that there are some First Aid supplies in another room and tells him to heal Eijiro as he wanted to have another fight to the death with him, showcasing how much respect he has gained for the young hero for his unyielding resolve and dedication.
