Arashi barely interacts with anyone else besides Mikoto, really. It's really jarring. 20+ volumes in and there's little sense of camaraderie between him and the other Triage members. There was that one mini-arc where he and Oriha had to work alone together because Mikoto was infiltrating a school whatever, and the entire time Oriha's just being adorable, doing her best to make it work because they were so out of sync with each other and kept screwing up, promising to be a better partner, and yet Arashi just gives her nothing to work with or play off of at all. Barely speaks back, cold shoulders her when she hugs him, where's Mikoto, my feet hurt, etc. It was just maddening to go through. I thought he was just bland at first but now I'm realizing I actively dislike him as a character. He's basically Orcbolg done wrong.
