Hiro stays behind while the rest of Squad 13 take part in the operation against the massive Klaxosaur horde on the Grand Crevasse. Led by the Nines, the human forces appear to be defeating the Klaxosaurs until a gigantic, Lehmann class Klaxosaur emerges and completely destroys Plantation 26. In an attempt to halt its progress, the members of Squad 26 are ordered to make a suicide assault on the creature but fail, and the monster starts towards Plantation 13. It stops and disgorges a hoard of small Conrad Class Klaxosaurs which Ichigo and the others begin fighting until Hiro in a training unit joins them. With Ichigo's help, he reaches Zero Two aboard Strelizia, but finds her almost losing her sanity from operating alone, until he confesses his love for her and they synchronize. Together, they power up Strelizia to the point of single-handedly destroying the Lehmann Klaxosaur and breaking open the doorway to the Grand Crevasse with help from the Nines. However, the Lehmann's cores are still active and about to explode, when a colossal hand emerges from the Grand Crevasse and retrieves the cores, astonishingly sparing the lives of Squad 13 and the residential area of Plantation 13.
