Foul-mouthed and not honest with himself, Izumi has a big attitude, is full of confidence, and assumes a detached attitude towards the world at large. He hurls spiteful remarks towards anyone he meets, like a violent-tempered cat.
Izumi used to be a popular model, but went on hiatus and entered the school in order to start over as an idol. He actually likes second year's Makoto Yuuki, who worked as a model just like him, but he never lets Makoto know.
