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 doesn’t 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 MARHeaven following in his hero’s footsteps?

After nearly committing suicide one day, Kurando finds himself in the unwanted company of Lisa, a buxom, blonde-haired beauty who informs the boy that she’s actually the reincarnation of a goddess, and from now on she’ll be his master. Humanity’s fate lies with the results of an epic war that’s currently taking place on Earth, and each goddess must designate an ‘avatar’ that will fight for her – unfortunately for Kurando, Lisa has chosen him for that task. Now, in addition to dealing with the demands of his new master, who is also his classmate, he must battle the countless foes that stand in their way… even though all Kurando wants to do is keep his sister Mafuyu safe from harm.
