Samejima Giichi is the Guardian of The Front of Armament's second & 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 Third Generation's Head,Hideomi. During this time, Mitomi replaced him as the Guardian. But when Ryuushin took over, he came back and once again took over the title.
He seems to have a fondness for Karaoke.
