Arc 3The Final Masks
Sera and his allies defeated Oswald and confronted Finality as he sought to test Dual-Phase Paradise. After using wishes gathered across the universe to overcome Voracity, Sera said goodbye to the departing Servants and brought his friends to Phantasmoon aboard the Astral Express.
- Himeko’s coffee creations knocked Feiying and Yaoguang out, and Herta and Black Tomb’s Curio-laden cooking led the group to ban Sera from the kitchen.
- Pearl delivered Screwllum’s custom starship to Sera, and the two explored Two-Dimensional City as she sought to understand love and find her own heart.
- Sera learned Oswald planned to obtain the power of Voracity’s remains and organized a coalition to expose and confront him.
- Oswald absorbed the Shadow of Voracity, but Sera’s allies severed his immortality and erased him with a combined strike.
- Finality summoned Weidi and Wojian away, then fought Sera’s group before Voracity swallowed him and Kiana drove the maw into the abyss.
- Sera and the geniuses built a machine to wrap reality in an Imagenesis forgery, while Xuzhao was revealed as Polka Kakamond and identified as Aha’s reflection.
- Xuzhao joined the Astral Express under Pom-Pom’s rules, and Sera’s friends enjoyed a beach outing before the Holy Grail War’s final battle.
- Sera and his allies fought Finality and Voracity, gathering wishes from across the universe until Xuzhao ended Finality’s suffering and the wishes became flowers in the sky.
- Sakura faded away as the Servants returned, and Sera brought Kiana and the others aboard the Astral Express to Phantasmoon, where he offered to help Xuzhao decorate its lake.
