With Raiga attempting to fight the inner darkness as Crow and Busujima hold him at bay, Mayuri decides to seal the blooming Eyrith with Biku covering her before being captured. Things seem hopeless as Eyrith begins to summon Horrors from across all time until Raiga's light is rekindled by Akari's charm. He uses his Lost Soul Garo form to reach Eyrith before his armor assumes Lumnious Beast form to fatally wound the Horror. He explains to Eyrith that her plan is flawed because the Horrors she have summoned have already been killed by his predecessors and other Makai Knights across time. Eyrith's body is destroyed with Mayuri reforms the Ady Slate around the Horror's surviving core. Though Zaruba mentions Eyrith may have reunited him with his parents, Raiga believes that he will find them on his own someday. A new problem soon raises from Mayuri not entering her deep sleep as Shido reveals that she will die from lingering Horror thoughts still within her mind. Though the only way to save her is to enter her mind and purge the Horror thoughts, it would only ensure that Mayuri will forget everything as she enters her rest. Raiga assures a fearful Mayuri that they will just begin again with everyone else's support before he enters her mind and purifies the Horror cage. Days later, with Mayuri still sleeping, Raiga and everyone else resume their usual Makai Knight activities as Busujima makes a grave for Akari. But one day, Raiga visits Mayuri's room after his rounds and finds her awake with her memories apparently intact.
