Young Kai has been passionately idolizing Ginta ever since his heroic battle in the War Games of six years ago. Since then, ARMs have become a common thing, Guardians especially! Kai himself does not have one though, and dreams big of being able to get an ARM like Ginta s! When his caretaker, the old ARM-smith that took him in after his parents deaths, sends him out on an errand, he is attacked by a bandit from chess! In his escape attempt, he finds more than he bargained for when he comes across Babbo! But, now with Babbo s awakening, the fake ARMs are going out of control! Is it Kai s turn to save MAR Heaven following in his hero s footsteps? (Source: Project Kurai Ryu)
