Description
Coal is a male capybara Jewelpet with ash brown fur, dark brown stubby paws, and jewel eyes crafted from dark purple coal. He wears a distinctive necklace of black coals and white beads resembling prayer beads. Representing endurance and perseverance, his magic grants humans the ability to endure pain or injuries and remain determined through challenges, officially described as providing "endurance and stamina."

In *Jewelpet Kira☆Deco!*, Coal serves as a primary antagonist within the villainous Decoranain, directly answering to the Dark General whom he considers his father. His origin reveals he was born from tar stuck to the Dark General's boot. Tasked with stealing Deco Stones and corrupting them with darkness, he recruits Opal and Io as lackeys, exploiting their hatred for Ruby and her friends. Coal frequently adopts a female disguise named "Coarumi" to infiltrate settings like schools, using charm to manipulate students. His plans often involve creating dark clouds of despair to undermine relationships, though these consistently fail, leading to repeated humiliation. Despite boasting allegiance to darkness, these failures gradually erode his resolve.

In *Jewelpet Happiness*, Coal works as a therapist and spa massager. His role remains minor until episode 37, where he discovers a doll named Angel, unaware it has been corrupted by the Red Moon’s influence. This storyline positions him unintentionally facilitating external threats.

For *Lady Jewelpet*, Coal appears briefly in episode 5, depicted massaging the character Sapphie, reinforcing his recurring association with therapeutic roles outside antagonistic contexts.

In *Jewelpet Magical Change*, Coal’s personality shifts toward bullying; he targets weaker individuals and those outperforming him, though he is not portrayed as inherently evil. He often ends phrases with the verbal tic "yami."

Trivia notes include his birthday on September 6 and variations in his power descriptions across media: while *Kira☆Deco!* emphasizes darkness manipulation, other sources define it as endurance, perseverance, or patience. He shares this birthday with *Yu-Gi-Oh! 5D's* character Crow Hogan.
