DD: ADBK Black Luster Soldier
Biography: He is often called the most dangerous swordsman that has ever lived, his blade has claimed the lives of many enemies in his quest for glory.
Known originally as Julian of Grandfarn before his legendary exploits, Black Luster Soldier is arguably Dark Magician's most notorious asset.
The two met long before the Yamimakai Invasion of Spell Henge, the young apprentice befriending young Julian after a chance encounter in the forest.
The two fought off a gang of Gokibores, and have been close ever since. When Dark Magician and Celtic Guardian made the 12 Arcane Knights of the Pentagonal Summoner, Black Luster Soldier was called upon to be part of it, and he immediately jumped at the chance to work with his old friend.
He came along with his right hand man, the strange-looking Buster Blader, and together they clobbered anyone who threatened Spell Henge and its surrounding areas.
