When Ninjoe returned from his vacation to Nu-Ikaros (built on the ruins of a destroyed floating fantasy city from another dimension) he encountered a Morpher clan agent (Agent of the Atomic Knight, a guy who appears to be actively sabotaging Go-Go city for some reason ) who tried to kill him because he participated in some secret operation during the P.E.A.K-Legion war. Ninjoe defeated him and stuffed his remains in a plastic bag to hand over to P.E.A.K via his boss.
