Babbo: The Legendary ARM!

After aiding Dorothy on her ÄRM hunt, Ginta's forfeited the ownership of the dormant legendary ÄRM Babbo, a sentient weapon that is just as vexing as it is fabled. Ginta's and Babbo's bickering eventually leads to their newly founded company crumbling, landing Babbo in the hands of two ÄRM thief con men, Moku and Chapu. However their identity is quickly exposed, and after Ginta forcibly reclaims Babbo, the two reconcile.
