Kazuki Suzuki 錫木カズキ

Widely acknowledged—even by himself—as the eccentric of IS1.

While his speech, fashion sense, and behavior are far removed from the norm, he actually possesses a rational and cool-headed side that surpasses even the other members. (Though he almost never reveals this side to anyone else.) He also dislikes his surname and gets angry when addressed by it.

He loves music and is one of the founding members of Odd-I's. He handles composition and lyrics for the band (though his lyrical sense is disastrous) and plays the keyboard. Even Amakasu, who is notoriously particular about music, holds him in high regard.
