堂島 誠一

A rescue worker attached to Special Elite Rescue Squad Sirius. Age 32.
Ever since losing his girlfriend 16 years ago in the Great Rokumei City Arson, he firmly believed in the idea that danger is man's territory, and women should just obediently go home... a quite antiquated idea indeed. And thus, he silently opposed Kazmi and Jun dispatching as rescue workers, hoping that they would find employment elsewhere and quickly back away from the front lines. He always had a brash personality, but his apprehension around the women caused him to use abusive language towards them.
When he learned the truth about the Great Arson, he accepted Watase's invitation without hesitation and got on board his LABO terrorist attack plot as a member of Q. Unfortunately, after he got Subject N out of Area Zero in the plan to get her outside the facility, he was found by Kuroda and Higa, and tragically met his last moments in the ensuing confrontation.
