Kento said that he saw the future. Touma, who desperately tries to talk to him, ends up fighting against his saying "This is the end of your story", that has now become "I must seal all the Seiken to save the world from destruction", and in its wake, Kento seals Tetsuo's Onjuuken Suzune! Touma's story is still far from over as he starts to contend with his new feelings. However, his first step has to be dealing with the effects of Primitive Dragon. To do so, Touma attempts to make contact with the mysterious boy, who keeps appearing before him whenever his mind is consumed by Primitive's rage. Meanwhile, Legeiel, who burns for revenge against Saber, appears in a powered-up form, overwhelming both Buster and Saikou. Yuri, who believes in Touma and continues to fight, also looks upon Kento and Rintaro's decisions as well.
