HERO is one of the main four protagonists that joins OMORI from the start of the game. He is the peacemaker of the group who tries to calm his friends down when they are getting worked up. He can sometimes be a pushover however, especially when being confronted by KEL. HERO is the tallest of the four and is possibly the oldest as well.
HERO's role in battle is similar to a support role in RPGs. He is able to make food to replenish the health of the party. When there is giant food in the way of your path, HERO can summon animals to eat them when you set him as leader.
Hero appears to be one of the childhood friends of OMORI and can be found in childhood photos with OMORI. He has sparkles around him in his pictures and seems to be a charmer. He is seen being more compassionate and closer to OMORI in his younger years.
HERO is positioned in the top-right corner of the screen during battle. He is able to heal the party with food or he encourages his friends in battle, affecting their status. Whenever KEL passes the ball to HERO during his Active Chain Skill, he gets hit.
In the "real world" his hair is much neater. He wears a sweater and is occasionally drawn with sparkles.
