Heinrich

Heinrich Hein was a legendary hero who defeated the vile, corrupt Monster Lord named Black Alice, or Alice 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. According to a rumor, Ilias ascended him to heaven.

However, the rumor is false. What really happened was that sometime after his battle with Black Alice, he revolted against Ilias and fought against her and her angel army, but 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 Lilith & Lilim, whom were sealed 500 years prior, they inexplicitly refer Luka as Heinrich’s descendant, claiming that he sealed them with the Angel Halo and that Luka’s looks, smell, and power resembles Heinrich’s. Granberia also claims that Luka’s power matches Heinrich’s which further proves the relationship. In Chapter 3, Micaela confirms this and also says Luka’s father Marcellus is the carrier of his bloodline.

Heinrich, being the former wielder of the Angel Halo, as well as his descendant’s beliefs seem 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.
