Beeble

About
Beeble was a mage, and a contestant in the Toushin Tournament. Known equally for his powerful magic and his unnerving demeanour, Beeble kept a clear head even in outrageous situations, such as one of his opponents transforming into an octopus. He was known to appear suddenly and without anyone seeing his approach.

For unknown reasons, Beeble murdered his fellow mage, Pluma Etoshiha. During the tournament, Beeble confirmed this fact to his opponent, Border Galois, possibly in an attempt to frighten him. Unfortunately for Beeble, this had the reverse effect, throwing Border into a rage at the murder and won the battle despite Beeble's powerful magic.

While Beeble's fate is not strictly confirmed, Border says that he "had no choice but to kill a shitbag like [Beeble]," and Kuri and Slasher talk about Border emerging from the match coated with blood.
