Hello, let's start with Kane and the Ranger going to the Elf Mausoleum ~ They were really defeated by the stone statue in the Mausoleum, and then the veteran with white hair that Kane met in his illusion was actually three generations of protagonists, so the only explanation is that the three generations of protagonists saved them and cured the Ranger with the magic in the Mausoleum.

Kane and his brothers (masked men) are dolls made by cults for the resurrection of evil spirits. Masked men were abandoned because of their poor quality. After he survived, he decided to wait for an opportunity to unite with his brother to take revenge on the cult. The female cadres of the cult are his lovers. Because Eustacia, as the saint of light, her own power will affect the power of the evil god to Kane, so in the end the bishop forced Eustacia to seal her own power, so there was no power to limit the awakening of the fiend, but Kane could not control it. The masked man subdued the fiend and took it for himself (although he was not a perfect doll, he mastered the method of controlling the fiend through cultivation), and the bishop fled in fear. After confessing his life experience to Kane, the masked man decided to send the ranger to another space to be imprisoned (as long as there is the blood of the Virgin of Light in the world, the power of the fiend is the nemesis, so it is not invincible). Kane, of course, did not allow him to attack when the masked man opened the portal, which led to the disorder of time and space, and both himself and the ranger were transported to other worlds.

Two weeks later, Kane returned to reality by revisiting the memory fragments, and then the plot ended, so the plot of Ai 4 was actually a pit ... Originally, the voice of Ai 5 was very high, but the studio was dissolved, and there was no Ai 5. I hope I can help you.
