HERO is one of the main three deuteragonists in OMORI that join OMORI's party. When tagged as the leader, HERO can use his charm to convince others to assist the party.

The HEADSPACE version of HERO wears a set of blue-striped pajamas. His hair is unkempt from sleep, as seen in his sprites. Like KEL and AUBREY, he lacks socks or shoes and his hair and eyes are purple. According to SPROUT MOLE MIKE, he is 5'7" at the age of fifteen. HERO is also the oldest and tallest of the party.
