Samejima Giichi is the Guardian of The Front of Armament's fourth generation. Described as having a nuclear fuse, because no one knows what he might do after he snaps.
He has an infamous reputation for being a handful for most of the delinquents in Town,always taking on more than one opponent at a time. He left the Armament once with Murata Juuzou because they couldn't stand the previous Head,Hideomi. But when Ryuushin took over, he came back.
He seems to have a fondness for Karaoke.
