Hayato

He knew the heroine when they were kids, before her polio symptoms showed. Despite being a fox demon, Hayato frequently came to the human world out of curiosity. Being young by demon standards, Hayato is rather immature. He's also used to fighting for attention from his large family. Hayato has trouble understanding that other people are different from him and is confused whenever others don't want to do things his way. In this regard, he comes off as being very self-absorbed. It's not that Hayato only cares about himself. He does want others to enjoy themselves and be comfortable in his presence, it's just that he has trouble considering things from a different point of view. Hayato prefers spending time outdoors.
