It is Raiga's birthday and as Gonza explains to Mayuri and Crow that making the cake is one of the duties Kaoru left to him, Raiga dreams about of the events that took place four years after his parents' disappearance. Injuring himself while training, Raiga met a Makai Priestess who heals while warning him of weak Makai Knights getting killed. Back at home, Gonza asks Raiga which cake he wants for his birthday party, but he refuses to celebrate it. Later at night, Raiga is visited by Rei Suzumura, who tests his strength before taking him on a Horror hunt. After Raiga correctly deduces that a woman sitting in the park is a Horror's vessel, on the grounds that she was reading in the dark, Rei lends the boy a Madō Lighter to have him handle her. Once he exposes the Horror, with Rei watching from afar, Raiga emulates Rei's fighting style against the Horror before she overpowers him. Luckily, Rei intervenes and forces the Horror into her true form before slaying the monster in front of Raiga. Soon after, Rei presents Raiga the choice to live a normal life or take the dangerous path of a Makai Knight as his apprentice. Raiga accepts and the two resume the Horror hunt. The next day, Raiga meets the Makai Priestess on the way home, thanking her for her help before giving her a present while learning someone dear to her has embarked on a dangerous journey. Upon returning home, Rei explains to a worried Gonza that he promised Kouga to train Raiga once he turned 10 and, as Raiga sleeps while they finished the preparations for the boy's birthday, Rei informs the butler that he will search for Kouga and Kaoru once their son's training is complete. Raiga then reminisces celebrating his birthday with Gonza and Rei and upon awakening at the present time, he does so with Gonza, Mayuri, and Crow as well.
