Harou is a spiky red-haired and green-eyed young man. He wears a fiery orange and yellow jacket; red and white long-sleeved shirt, white pants, red boots; and lastly, a dark green choker. His outfit and appearance gives the impression of a magnificent, fiery brawler and an older brother figure to Harubaru and Raichi.
Harou has an upbeat, optimistic and brotherly personality. He is always seen with a bright smile in his face. Despite being a champion, he is down-to-earth and is more than willing to share his techniques to younger brawlers. He also sees the good side in everybody he meets. This earned him the respect and affection of Harubaru, Raichi and Tatsuma who all look up to him as their 'Big Bro Haro' (ハロ兄, Haro nii?).
Harou made his debut in the nineteenth episode. He taught Harubaru and Raichi about Bakugan, and the two refer to him as "Harou-nii" (Big Brother Haro). Tatsuma hinted that it was Harou who gave him pointers on Power Battles.
Harou was the BakuTech Colisseo's conference champion three times, consecutively. He inspired Harubaru and Raichi to become brawlers.
He is called "Haro Dodgy" and "King Harou" in the BakuTech Colisseo.
