Rip Slyme
Ilmari attended the same primary and middle school as Ryo-Z. During this, they became the founding members of Rip Slyme. After switching several schools, Ilmari then left for an international school. While there he met fellow Rip Slyme member Pes. Quitting school in the middle of his final year, he returned to Tokyo, reunited with Ryo-Z and formed "Gibinibanko" (ギビニバンコ).
