Arc 5The Road to Phantom Lord
Riyao joined Fairy Tail’s adventures across the Eisenwald, treasure hunt, and Galuna Island incidents while hiding the extent of his powers and pursuing his own experiments. After Phantom Lord attacked Fairy Tail, Riyao helped set retaliation in motion as its mobile headquarters approached Magnolia.
- Riyao helped Fairy Tail defeat Lullaby, gathered demon factors from its remains, and accompanied Erza to the Magic Council hearing.
- Riyao let the guild hunt for his planted treasure clues, then revealed that the chest held embarrassing recordings of Fairy Tail’s members.
- Riyao secretly followed Natsu, Gray, Lucy, and Happy to Galuna Island, where he joined them in confronting Lyon’s followers and the awakening of Deliora.
- Riyao transformed into a demon and fought Natsu, Erza, and Mirajane before healing Natsu and returning with the group to Fairy Tail.
- Riyao’s experiment restored Ur to a wooden body, and he brought her to meet Gray and witness the guild’s lively chaos.
- After Phantom Lord damaged Fairy Tail’s hall, Riyao and Mirajane found Gajeel attacking Levy, Jet, and Troy, and Riyao arranged a plan to provoke retaliation.
- Riyao treated Gajeel and altered his memories while Makarov led Fairy Tail against Phantom Lord, whose mobile headquarters then advanced toward Magnolia.
