Heinrich

Heinrich Hein was a legendary hero who defeated a vile, corrupt monster named Black Alice, or Alice the VIII (Eighth), 500 years ago. Using the power of the Four Spirits, he ended her life as a means of bringing peace to the world.

However, sometime prior to Black Alice’s defeat, he revolted against Ilias and was sealed in the Sealed Sinner’s Prison for all eternity, the ultimate punishment where one cannot reincarnate. As Luka nears the jail, the Angel Halo suddenly shines with a bright light, seemingly reacting towards Heinrich’s spirit. According to a rumor, Heinrich was taken to heaven by Ilias.

According to Lilith, Heinrich once wielded the Angel Halo, and Luka is his descendant. Granberia also claims that Luka’s power matches Heinrich’s which further proves the relationship.

Heinrich being the former wielder of the Angel Halo as well as his descendant’s beliefs seems to indicate that Heinrich was a pacifist and thought coexistence between monsters and humans was possible. Like Luka, he may have eventually discovered that Ilias was the instigator that denied coexistence and fought against her, leading to his ultimate demise.
