Oboro is a boy with a jovial and casual personality, very prone to making jokes and witty comments with innuendos. His energetic and goofy persona was similar to that of his classmate Hizashi Yamada. He is primarily motivated by logic, he often comes off as a tiny bit cold to strangers, apathetic, and a bit impatient for his friends shenanigans. Hizashi maintains the eccentric persona of a radio host. He often poses when he talks and maintains a certain level of excitement or volume.
