Heizou is the back-up rapper and electric keyboard player of the group. He's the last member to join the group, and his identity was only revealed to the public in the middle of 6REEZE's first album release.

Since then, he struggles to adjust with the group. Heizou couldn't help but feel sad and jealous that 6REEZE are close with one another. He feels left out most of the time. As his manager, you caught Heizou sitting at the corner of the room again while 6REEZE were hanging out together.
