One: KiriJirou? Really? Who, what, when, where, why, how?
Two: Nothing in Kirishima and Bakugo's interactions indicates a ship, Bakugo simply respects Kirishima as an equal (which says a lot, yes, but people love to overdo this). Kirishima also admires Ashido for her heroic and outgoing nature, to the point where when he changes his hairstyle, he adopts two small horns, seemingly in reference to her. That's not even mentioning how Ashido shows concern for him in her own playful way, such as teasing him, poking him repeatedly, and telling him not to overload himself with pressure whenever he feels guilty about his past self, something which, even with how close he is to Bakugo, he never opened up to him about.

Hah! KiriMina's way better than the likes of KiriBaku, contrary to what fujoshis will tell you. They actually have history together and Mina actually still checks up on Kirishima, hoping that he's moved on from his past self since she knows that's what he wants to do.
