AppearanceIsao is a green hedgehog with messy green hair tinted with dark green on the tips and also on the tips of his quills and dark violet eyes. He wears the Kyokukou Academy boys uniform which is a black button shirt with a red jacket and black pants.
His casual clothes are a long sleeved shirt with a white t-shirt over it with jean knee long pants and gray sneakers.
Isao is a free-spirited young boy with a hipper attitude and can never say no to a challenge. But unfortunately he is a shameless pervert who often flirts with the girls from his group, the middle schoolers and the female members of the Kamihime Jiyuu no Faita. But other than that he can be very considerate and gives great advice to others and knows how to comfort people. He is especial protective of his brother Junichi the Hedgehog and his grandparents. Isao has a talent for Kyudo and has been practicing it for seven years.
Isao also seems to have affection to Yuffi the Hedgehog but he has no romantic interests in her, but he does enjoy harassing her and the other female members. He is somewhat afraid of Rin the Wolf but he also shows affection to her. His main interests in his teasing is Yuffi, Rin, and Blaze, but he will tease Asami every now and then but not as often since it is shown that he is terrified of Ichiro the Fox.
Not much is known about his and Junichi's parents since their mother died giving birth to them and their father abandoned them when they were newborns so they were raised by their grandparents. Isao and Junichi grew up with the acceptance of their grandparents when they discovered that they had Electrokinesis. They trained themselves to control their powers when they were young and with the support of their grandparents.
When they got to middle school Isao and Junichi meet Yuffi the Hedgehog and Isao would constantly flirt with her, which only gained him many slaps in the face. But when she discovered they had powers like her they eventually became friends and later on they helped her and Rin form the Kamihime Jiyuu no Faita.
Isao has Electrokinesis and he is able to charge electricity in his hands and also control electricity. He is also unaffected by electrical currents. He also has an especially made bow that is made of metal that is bendable and has many arrows made of the same material that is able to charge up the electricity that he controls.
His only known battle move is Electrical strike and its is used when he shoots an arrow that has been charged up with electricity and the shockwave it produces can destroy anything in its path.
