The "perfect future" that Ryuzu yearns for is at hand. In the critical moment, Chrono, Tokoha and Shion face the "final judgment" in order to prevent that future. The battle begins, with the future of Cray and Earth hanging in the balance.

Thanks to Shinonome`s meddling with the system, Ibuki has become immune to the "siren song" of Ryuzu`s imaginary world. Ibuki confronts Ryuzu alone and challenges him to a fight with everything at stake!
