Kawaguchi Metal Fittings Corporation

The is a factory in Tokyo's Torigoe District.

Overview
From what was seen of it, the corporation is a tall factory with a gable roof, a long row of square windows at the top which were shattered due to external damage, and a banner with the name of the corporation on it. During the Flame Human invasion, the entire inside of the building was set alight, leaving dangerous debris everywhere making it hard to maneuver in.

This corporation is a factory that specifically works in manufacturing metal fittings. It caught ablaze when the factory manager's wife — Saeko — fell victim to the Spontaneous Human Combustion and became an Infernal, leading her to go berserk within the factory. It was speculated by Iris that the building may have meant a lot to Saeko, as she was trying to run the 8th Special Fire Brigade away from it. Soon after, Shinra Kusakabe used his abilities to impale Saeko's core, purifying her soul in the process. The flames were then put out by firefighters.
