Haru can be considered as the peaceful, caring member of the Scarf Heroes. He cannot stand to see his friends arguing, nor can he stand seeing them sad. He tries his best to comfort his allies when needed, and will always put his friends far ahead of himself. Haru can also be considered the underwhelming, as though he is part of the Scarf Heroes, he believes he cannot reach the amount of skill and strength as the others. Instead, he takes it upon himself to practice ranged attack, as well as first-aid and support. He is considerably known to be the one that asks the most questions to his comrades, yet answers questions regarding the whole group the least due to his lack of self-confidence.
