Ryuga, who has been brought back to their hideout by Takeru and Aguri, is reunited with his mother Hakana who is revealed to have been the young girl that Burai rescued before he restored her age and memories. Hakana then reveals how she and another priestess named Sari took part in a ritual under the Hill of Zedom's Arm fifteen years ago in an attempt to restore the Garo armor's radiance with support from Burai, Sari's brother Rikyo, and their Makai Knight protector Sonshi. However, after a Mad? Horror Plant was created, a grenade detonated and Zedom's seal turned into a Horror gate with Burai becoming separated from the others during the chaos and Hakana knocked unconscious. After Sonshi dispatched the Horrors, he ended up being turned into a Mad? Horror by the mastermind of the incident: Tousei Kaneshiro. On Tousei's orders, Sonshi was forced to devour Sari and then mortally wound Rikyo before spiriting off Hakana to the Hill of Zedom's Head under Vol City. After he woke up and promised a dying Rikyo that he would care for Rian, Burai believed Hakana to be dead. However, she was instead forced into germinating more Mad? Horror Plants at the cost of her memories as she slowly became a child overtime. With the truth revealed, Ryuga apologizes for not realizing she was alive when he first heard her song. Soon after, Hakana restores Ryuga's eyesight by sacrificing her own. Thanking Burai for allowing him to fulfill the promise he made to his mother, Ryuga is joined by the other Makai Knights as they race to rescue Rian.
