The gate above Tatsunagi HQ slowly crumbles, which prompts everyone to evacuate the building while Aichi and Kai are still on the rooftop. Much to Aichi's shock, Kai reveals that he never was completely Reversed and was consciously Reversing others despite knowing the consequences of his actions, all for the sake of becoming the strongest. He also wants to fight Aichi again before he returns to normal in order to see who is the strongest between the two of them and whose path was right all along: his or Aichi's. And so, Aichi and Kai cardfight each other while everyone else watches from below. Thinking that he will only hurt Aichi and his friends again, Kai intends for this to be the last fight he will have against him and will be gone once it is over. However, Aichi tries to convince Kai that he is not alone and further exclaims it was because of him that Aichi is the person he is now. Despite Aichi's cries to bring him to his senses, Kai continues the fight by riding Dragonic Overlord "The Яe-birth"...
