Luck

How Luck joined the Tourney
Luck Voltia is a member of the Black Bulls, a borderline psychopath who uses Lightning magic and is always smiling regardless of circumstances, giving him the nickname "Luck the Cheery Berserker." Born a commoner within Yvon Village and raised by a troubled woman before she died of stress, Luck was instilled with the notion that winning a fight is the same as being loved. This motivated him to fight stronger opponents to test his strength, joining the Magic Knights while gaining infamy from his conduct of nearly killing an opponent in the entrance exams. Later during the raid of the Midnight Sun's base, Luck ends up being possessed by the elf spirit Rufel (ルフル Rufuru) as a result of Patry's ritual. But Luck is released from the spell after Rufel is defeated by Magna and Vanessa with Asta exorcizing the elf spirit while giving him closure.

While on an assignment, Luck is chased by an ICPO cop assassin named Beauty who is promised a Christmas bonus for killing him.
