Saburo Hazuki

Saburo Hazuki (葉月 サブロー) is an eccentric and passionate scientist who was a member of the Energy Management Center years ago prior to Messiah's creation, creating the framework for the primary Go-Busters' Buster Machines. When he left out of a conflict of interest, Professor Hazuki devised Tategami Lioh and continued working on it up until his death. However, Professor Hazuki copied his mind into Tategami Lioh's control system.

Saburo Hazuki is portrayed by Ichirou Mizuki (水木 一郎), who also voices the GB Custom Visor and Tategami Lioh's AI.
