World-Splitter -Gladius-.The Amaterasu report on their mission to Gaum, finding Aldea with her ability to warp space and the Tri-Head dragon. That night, Hayuru returns alone to confront Aldea, but is easily defeated. The other Amaterasu go to her aid, but Aldea recalls the Tri-Head Magitech. When Aldea learns Aine's HHG name, Zeros, she seems to recognise her. Commander Reiri then arrives and drops the simulator room for Kizuna to revive the powerless Hayuru. Hayuru admits her inadequacies, and how she failed to protect the people she evacuated from Japan. Kizuna offers to Hybrid Heart with her and she achieves Climax Hybrid. She emerges fully recharged and destroys the Tri-Head. Aldea attacks them all, but when she fires at Kizuna he responds by materialising a sword for the first time. When Aldea opens the portal for reinforcements, she is recalled and they retreat just as the Amaterasu from the Megafloast West USA arrive. Aine and Yurishia realise that prudish Hayuru reached Climax Hybrid with Kizuna.
