Leohart

Leohart is the current Demon Lord who lives in the Demon World, and he is also the younger adoptive brother of Liala. Leohart is a highly intelligent and powerful yet a relatively young demon. Although he maintains a calm and collected demeanor from a young age, he has been driven by a hatred of the Demon Council and love for his adoptive sister and the demon world as a whole. Leohart despises the constant warring between the various demon factions and dreams of one day creating a united and peaceful world for he and his loved ones to live in, and towards that end, he greatly desires to kill the members of the Demon Council, which he perceives to be at the heart of the corruption in the demon world. Unlike most of the demons who are mostly cruel, selfish, and power-hungry using their subordinates as mere tools, Leohart deeply cares about them as he prevents them from interfering in his clash with Jin, knowing they are no match for him. He also sends Lars to rescue Gardo after he was impressed. Leohart is also trying to prevent unnecessary loss of life as this is seen when he proposed a decisive battle with only a few elites from each Faction to avoid them.
