Hiroto is a guy who seemingly has his head so far in the clouds that he can never have a constantly running conversation. However, he seems to be able to talk about a few things for hours on end without stopping. Those few things are things he tends to call "station points" as they can get him "talking like a train." He also calls these subjects "probably the only way to be friends with me." As he notes that unless you're interested in them then you most likely would not find him to be an interesting friend. This sort of seems to hint at some issues he has with himself. As the SHSL Geologist, its obvious that one one of the "station points" is rocks and things like the Earth. However, as the story progresses, he begins talking more about people who've been kind to him even if he's a bit strange, especially including Jun. June and Hiroto, like Natsuki and Yuuki, seemed to click almost as soon as they met, and became friends quickly. Hiroto's almost constantly tired.

Hiroto's voice should be low-medium toned and also should have a very distracted tone.
