It is revealed that Moo is actually Holly's missing father, who merged with an evil spirit after being banished from his village. Determined to separate Moo's evil spirit from Holly's father, the group continues their search for the Phoenix, defeating Moo's strongest minions, the Big Bad Four- Pixie, Gali, Grey Wolf, and Naga. In their travels, the gang befriends and aids many monsters as they continue searching, unlocking as many Mystery Disks as possible in the hopes of finding the Phoenix. One of these unlocked monsters, Monol, tells the group of a previous war between Moo and the Phoenix (as part of a larger war between humans and monsters, who exploited monsters as workers and companions in a futuristic society) that destroyed much of the world and weakened the two entities into their dormant states, separating their body and souls.
