Main Character

Much of the main character’s past is shrouded in mystery. Having lived his entire life believing he is a normal human, he discovers that he is actually a Demihuman with a powerful seal placed on him to block his innate power from growing. However, even after breaking the seal, his true origins remain a mystery. Early in the story, it is made clear that he exhibits the traits of several ancient powerful sub-races of demons, including an Archdemon Lord.

Serenity

Serenity is the first character introduced in the story prologue, and is a 23-year-old Demihuman who lives at the mansion. At the start of the story, she is beginning her last year of college as a fifth year Senior, due to studying two undergraduate majors: Finance and Criminology. Like most Demihumans, she has two forms, being able to resemble a human or Demon. However, while stating that she is mostly half Inferno Imp (Fire Devil), her gray complexion when transformed suggests that she has 'something else' in her ancestry.

In the story, she is a female Knight who bonds with the main character’s first Void Queen, and is unlocked after completing Chapter 8 of Part 2 of the story. The character Serenity originates from the series Innocent Devil’s Harem by Kaizer Wolf, and is one of the primary two heroines in Book 1 and 2. She is featured on the cover of Book 2.

Gwen

Gwen is the second character introduced in the story prologue, and is the first Companion unlocked in the game by default. According to her, the main character forms a special bond with her by 'claiming her,' a feat normally only feasible for an Imp Lord.

The character Gwen originates from the series Innocent Devil’s Harem by Kaizer Wolf, making her first appearance in Book 3. She is featured on the cover of Book 5.

The character Mel originates from the series Combat Healer by Kaizer Wolf, and is featured on the cover of Book 1.

Miriam is the Succubus who owns the mansion, having bat-like wings and a midnight tail, and is the primary character who drives the plot of the game, serving as a teacher and guide for the main character.

For an unknown reason at the start of the story, Miriam has chosen to participate for the first time in the challenge for the Void King’s throne, revealing early on that she is a Void Queen who is currently too powerful for the main character to bond with.
