Gender: Male Birthday: March 6 Blood Type: O Height: 151.5 cm Weight: 44 kg Likes: Meat, curry, pudding Favorite Subject: PE Known as Hiro. His mother, Momoko, is a hero, and he dreams of becoming one himself. He has red hair and wears a red headband (which he calls his hero mask). He wears a black inner shirt with a red and white sukajan jacket and beige pants. He is a hot-blooded person who can't ignore people in trouble. Because he admires heroes so much, he shows intense anger toward Hibiki, who only follows missions and can't decide for himself, and Ogami, who takes things too far by deciding what's right or wrong based on his own standards. While he has a strong sense of justice and cares deeply for his friends, he is also a bit of a show-off. He has a flawed side, such as secretly eating expensive sweets his mother bought and dragging Aoi and Toko-tan into his schemes to cover it up. In the first episode of the story, he put the two of them in danger at the end of a video and was slapped by Momoko, who told him, "Putting your friends in danger makes you a failure as a hero." He is also a huge coward and freezes or shakes when he sees ghosts. A hero of the Hero Alliance. Rank 3. Ability: "Absolute Strongest Hero" (powerful, but he can't control it perfectly).

He has blue hair and wears glasses. He wears a white dress shirt and blue trousers. He wears a blue tie and has a red armband on his left arm. He has a serious personality and is the voice of reason, often scolding the reckless Hiro or the airheaded Toko-tan, serving as the straight man of the group. He is quite scary when angered, once trying to snap the talkative He-san in half and shouting "Idiots!" at Hiro and the others. He snaps if anyone says he's "only good at studying." He is highly intelligent and excels at reasoning, scoring high marks on school tests. A very kind hero of the Hero Alliance. Rank 3. Ability: "Inferential Conclusion."
