Heikou (ヘイコゥ) is a member of the band 04Tobizbits and the band's drummer.
Although his appearance makes him look rowdy, he actually has a very pure personality, and is often tricked by people. He calls himself "the weakest to alcohol in the band world" but still participates in launch events. He seems to love Gudetama.
- He is based on KOUHEI, the drummer of 04 Limited Sazabys.
