Cain Distarol is an elderly fairy scholar residing in Timoon. He is a gray-haired man typically seen in a suit and often accompanied by a crane. As an ordinary human, Cain possesses no additional powers or combat abilities; his expertise focuses solely on fairies and related subjects.

Cain shares a longstanding friendship with Damien Carme's father, connecting him to Damien Carme and placing him within a network knowledgeable about fairy lore and artifacts.

His documented involvement centers on the Black Fairy Tome. Marlya Noel and Free Underbar visited Cain to inquire about the artifact, coinciding with a visit by "Sweetie" Bitter Sweet. During their discussion, Axel Laboo orchestrated an attack using a fairy to steal the Tome. Although Axel escaped with it initially, collaborative efforts between Dorothea members and Bitter Sweet led to its recovery.

Following the Tome's recovery, Marlya and Free returned to question Cain and Damien about its origins. Both deliberately withheld the information, refusing to disclose how they acquired it. Cain and Damien also denied any knowledge of Veronica when questioned by Marlya. His narrative role remains tied to his scholarly knowledge and his guarded connection to the Black Fairy Tome.
