What Ten wants more than anything is to be the Farmagia with the strongest buddy monsters in the Felicidad Underworld. But the stakes become much higher when Felicidad's denizens find themselves in sudden need of a new ruler.

Ten and Leii desperately try to fend off Zanas when he attacks the orphanage. Nares saves the day, but only after much damage is inflicted. This serves as the motivation for the young Farmagia to support Nares when she declares herself in open rebellion against Glaza, the new Magus.

Ten, Leii, and Arche infiltrate Perfectus as a commando squad in order to eliminate Manas, the Oración general who leads it. There they encounter Emero, their friend who's been missing since childhood. Ten is exuberant at the reunion, but Emero's reaction is decidedly less cordial.

Ten wishes he could use Unite Blitz the way Emero does. Emero shows up again and for some reason he's even more hostile than before.

With Arche recovering from a sudden health issue, Ten and Leii go alone to Rahatluk to deal with Corpus.

Corpus has taken Chica captive, and Ten, Leii, and Emero have little choice but to fight him on his own terms.

A troubling secret about Arche comes to light, and it leads her friends into a challenging situation.

Ten, Leii, and Arche go to Sonrisa to rendezvous with Anzar and work out a plan for defeating L'Oreille.

Nares goes to Nadeyat'sya for peace talks with L'Oreille. But is there more going on than meets the eye?

L'Oreille attacks the heroes with her dark arts, and it dredges up paralyzing trauma from Leii's past.

Ten and friends are forced into battle against Reaper versions of all the Oración Seis, including Nares.

The situation seems dire, as the Farmagia heroes must now contend with Magus Diluculum, their mightiest foe.
