Yuuki Yuuna Is a Hero

OVERCOMING ADVERSITYFacing up against all seven of the remaining Vertex, the girls start to fight against the first one, only to be caught in a trap by another, who uses a loud bell to disable them. Itsuki manages to stop the bell, but then three Vertexes merge to form a single more powerful Vertex, proving resilient to their attacks. Not willing to give up, Fu and Mimori use their trump card, the Mankai form, to defeat the combined Vertex, while Itsuki uses her Mankai form to stop a smaller, faster Vertex from reaching Shinju. Fu then risks herself to buy time for the others to seal the remaining Vertex, whose core is discovered to be a massive one positioned in the stratosphere. Yuna and Mimori head to space together in order to fight against the core, using their Mankai forms to destroy it. Following the battle, Karin is relieved to find everyone alive and well and reports their victory to Taisha.
