|← Determination||The End →|
The final battle against the Vertexes has arrived, and Yuna and Wakaba decide to split up and use their Trump Cards. Using the power of Shuten Doji, Yuna tries to chase after Vertexes that are heading directly for the Shinju, but her fails. The mental effects of the Trump Card begin to sink in, telling her that being a hero is nothing but suffering and pain, leading her to question if it is worth fighting for. However, by reaffirming her devotion to protecting others, Yuna is able to overcome it. She charges at the Vertexes, knocking them down one by one and suffering severe internal damage in the process. Once she reaches the Shinju, Yuna collapses, but is glad she "made it" as her consciousness fades.
Elsewhere, the increasing swarm of Vertexes and the effects of the Trump Card cause Wakaba to temporarily become consumed by anger and revenge. She returns to her senses, however, upon remembering Yuna and Hinata and changes her focus to fighting for their sake. She uses Daitengu's power to destroy the remaining Vertexes, assuring them that as long as they have something to protect, they will always be stronger than they are. After the battle, Wakaba collapses. She calls out to Yuna as she loses consciousness, but Yuna is nowhere to be found.
