Okarun is a self-described socially awkward individual who has a consuming interest for the paranormal with his main focus being the existence of aliens and cryptids. This interest goes all the way back to his childhood where he tried to make contact with aliens in a desperate attempt to make friends, having grown up without a single one in his life due to constant bullying. As a result, Okarun developed an inferiority complex where he believes that he is incapable of fitting in with others or that people are better off not associating with him. Even after making friends with Momo Ayase, Okarun still seems to retain some low self-esteem. After Jiji stepped back into Momo's life, Okarun thought to himself that he could not compete with him when it came to being her friend based on his observation on how entertained Momo was being around him and had almost come close to ending his friendship with her as to not be a bother. According to Momo, Okarun's real problem with making friends was that he was too quick to make assumptions about others judging him, which resulted in him subconsciously keeping others at arm's length.
