While fighting a Horror, Raiga encounters a mysterious man named Matō who devours the creature while revealing himself as a Makai Knight-like Horror named Gogeet. Gogeet then proceeds to fight Raiga while offering an alliance to the Makai Knight. Though Raiga refuses the offer, he is unable to land the deathblow when a little girl named appears at Gogeet's side, the Horror introducing her as his daughter Ai before taking his leave. After a night of searching, Raiga reports Gogeet to Jiiru as she tells him to confirm if he is one of two remaining Ady Slate Horrors. Jiiru also reminds Raiga that Eyrith's sealing is more important when the question of Mayuri's fate after their mission has ended is brought up. Mayuri and Raiga split up to search for Matō, with the former finding him and confirming to possess Eyrith's seed. Having suspected Eyrith's presence, Gogeet explains that Ai is only an illusion of a deceased girl that he is recently able to conjure. Mayuri regroups with Raiga and Crow, revealing what she has learned, and they hunt down Gogeet and the Makai Knight fight him for several hours past night fall. Raiga eventually musters the nerve to strike down Ai and gravely wounds Gogeet's arm as the Horror was about to kill Mayuri. Gogeet then assumes his true form, unconcerned with losing his illusion as he reveals that Ai was actually his first victim. This revelation enrages Raiga as he equips the Garo armor to attack Gogeet without mercy before killing the Horror. Just as Mayuri is about to seal Eyrith's seed, she is stopped by the figure responsible for unleashing the Horrors of the Ady Slate in the first place. As the figure explains his reasons are tied to the Makai Flower, he is revealed to be someone who Crow recognizes.
