Dimoni Vermell (Red Demon or Red Oni) initiates the narrative conflict by kidnapping a young girl named Aya, compelling the protagonist's intervention. His antagonistic role stems from coercion, as he operates under the command of the more powerful Kurooni (Black Oni), serving this entity out of fear or obligation within a demonic hierarchy. Following his defeat in battle, the Red Oni undergoes a significant shift. Freed from Kurooni's control, he transitions from antagonist to ally, actively assisting the protagonist in rescuing Aya and liberating a village terrorized by both demons. This marks his redemption arc. His narrative trajectory culminates when the protagonist propels him physically upward into the clouds, acknowledging the Oni's desire for purpose beyond destruction. This act integrates him into the celestial realm, granting him a defined position serving the thunder god and signifying a complete departure from his former earthly conflicts.
