Leorg Indu

Leorig Indu (リオルグ・インドゥ, Riorugu Indu) is one of the Demon Emperors and the head of the Indu family.

Appearance
Leorig is a young man with long black hair and has three earrings on his right ear and two on his left.

Personality
Leorig is very prideful in being royalty and is ready to even kill his own brother if he brings shame to the family. However, in flashbacks, it implied that he and Zepes used to have a closer relationship.

History
After seeing Zepes losing, he decided to punish him and killed him for being that weak and shaming the family. He then went to the arena to face Anos as a royalty he could choose who he can face. Anos then insulted the royalty, which angered him. As Anos said he was the founder, Leorig got even angrier to lying and other royalty members came to the arena to punish him, but Anos told them to bring all who wanted to fight him as four on one won't be enough. As everyone came to the arena, Leorig wanted to give Anos ten seconds to cast his most powerful spell, but Anos told him he is already too late and then everyone's magic started going out of control. Anos warned them they need to control their magic or they will die, but moments later all exploded with only Leorig surviving. Leorig then decided to risk his life and used origin magic, which had devastating effects on the arena, but zero effect on Anos, who explained the secret of the magic and that it can't hurt him. He decided to give Leorig an opportunity to meet his expectations and revived Zepes as a zombie, who now had more power than Leorig. Anos told him to use their brotherly bond and turn Zepes onto his side so that they fight him together. However, their bond wasn't that strong, Leorig got killed by his brother. Anos then used his revive magic and revived both before leaving as the victor.

Abilities
See: Magic

Demon Black Storm Emperor : A powerful Black Lightning created from within his hand, that eventually grows into destructive typhoons. Because it is a spell using Origin Magic, Leorig used the Demon King of Tyranny as its origin, thus it didn't affect Anos even if Leorig didn't know Anos's true identity or if Leorig believed it was someone else.

Zepes Indu
He holds extreme disdain for his brother thanks to Zepes' loss at the hands of Anos, believing Zepes to be weak before facing Anos himself. As noted by Anos, Leorig and Zepes do not possess a close relationship, better described as a spoiled child and an angry father.

Trivia

 * In the anime, Leorig attacks Anos the night after the entrance exam, while in the manga and light novel, he attacks him immediately following his victory against Zepes.
