Jien Du 「ジエン・ドゥ」 is a mysterious mage and an old friend of Julius Novachrono.[1][2]


Jien is a man with shaggy, black, medium-length hair that hangs down and covers half of his face.

Jien wears a white collared shirt underneath a purple robe. Over this, he wears a black, long-sleeved coat with gold trim. A black belt wraps around his waist forming an x-shape, and his grimoire pouch hangs on the right side. He also wears a pair of black gloves with gold trim and a pair of black boots. On top of everything, he wears a short, black, hooded robe.


Jien is obsessed with seeing new and interesting magic, a trait he shares with Julius and with collecting relics.[2]


After a relic is stolen, Julius Novachrono reaches out to Jien and requests his help in locating the stolen relic. Julius sends Asta, Noelle Silva, Klaus Lunettes, and Mimosa Vermillion to visit Jien's forest home. Jien sets up a series of traps and tests for the Magic Knights.[2]
