However, as Mayuri explained in the worst-case scenario, Eyrith would bloom within 100 days and enable Messiah's return by removing the boundaries that separate the human world from the Demon World. Though Raiga nearly succeeds in capturing it by slaying Idora once he finds her, Eyrith escapes by transferring its essence into the Ady Slate Horror Gogeet. As such, it is deemed impossible to capture and seal Eyrith until the remaining Ady Slate Horrors have been slain and sealed first. Despite Raiga finding and slaying Gogeet, Eyrith transfers into the last Ady Slate Horror left, Jienda, which is soon captured and Eyrith's seed is extracted by Eiji Busujima. Accepting Busujima's wish to bring back his lover, Eyrith produces a cloned body of Akari that will come to life the moment Horror is fully grown and blooms. When the time of her blooming draws near, Eyrith intends to turn Mayuri into her host to reach the place where she can bloom. However, Crow offers himself to her in order to spare Mayuri. Seeing that the now-repentant Busijima no longer has his original wish, Eyrith cancels her pact with him and brutally beats him up when he tries to stop her. Once reaching her destination, Eyrith leaves Crow's body and assumes her true human-like form before proceeding to grow into a giant tree. From there, recruiting Zaji to wipe out the line of Garo by targeting Rekka and Rian, Eyrith proceeds to spirit numerous Horrors from across time and space so that the bulb on top of her body can bloom and she can unleash a Horror army on the world. When Raiga attempts to destroy the bulb, Eyrith manifests a nude demonic version of her human form to fight him. Ultimately, the fight ends with Eyrith revealed to be the one who took Raiga's parents from him before she uses her temporal powers to suck out the Makai Knight's remaining time in the Garo armor so he can drive off his friends in his Lost Soul Beast form while she can bloom without interference. However, Raiga is later awakened as the Light Awakening Beast Garo and promptly resume to foil her plans. In a desperate bid to further demoralize Raiga, she tells him that all she has summoned are Horrors in both the past and the future and how his attempts have ended in vain, to which Raiga asserts that they will be taken care of by the Makai Knights of the past and future, as he proceeds to destroy the rest of her tree body.
