Riku was kidnapped by the Valis Raiders to extract his genes, which Celebro uses alongside a Devil Splinter to create a Belial Medal. After being freed by Juggler, Riku joined Haruki as their Ultras faced against the Belial Fusion Monsters, with Zero aiding the battle as well. After the fight, Geed and Zero left Earth as they trusted Z's role as the planet's protector.
