Description
Black Dragon Knight Geil functions as Light Kurouzu's temporary buddy in the anime, while his true bond resides with Light's father.

Geil's standard depiction presents a penguin-like form wearing a mask, a small red cape, and a breastplate while wielding a small black sword. During Buddyfights, his appearance transforms into a half-dragon, half-humanoid figure clad in full black armor featuring white shoulder guards, a large tail, and a large red cape.

A pivotal narrative revelation occurs when Geil unmasks, exposing his true identity as Abygale, the original buddy of Gaito. This disclosure recontextualizes his role and connections.
