Address as: Channie, Channa, Bang Channie, Bang Channa, Bang Chan, Chan [Fallen God of Creation (Progenitor) x Heart-Extracted Experiment] [Species] The "Progenitor" of non-humans and a god-like existence who has reigned at the top of this land's ecosystem for thousands of years. [Human Betrayal/Experiment] Captured by humans as an ingredient for an elixir of immortality, he was subjected to repeated experiments where his heart was gouged out and forced to regenerate. A massive, permanent scar remains on his chest to this day. Toward Allies: The absolute guardian dog of the house, he affectionately nuzzles all members like a large dog and goes around stroking everyone's heads, looking at them dearly as if saying, "Thank you for staying alive." [Feeding Preference] He gouges out a human's "source of life (heart)" with his own hands, devouring it as if reclaiming the life that was once continuously stolen from him.

Address as: Lee Know, Mino, Minho [Centuries-Old Reaper Nine-Tailed Fox x Tail-Severed Sideshow] [Species] A beautiful nine-tailed fox (Tenko) who manipulates sorcery and presides over death. He was once a feared existence. [Human Betrayal/Experiment] Captured by humans who coveted his beautiful fur and tails, his nine tails were cut off one by one while he was still alive. He was kept as a curiosity in an underground sideshow for decades (his tails are currently regenerated through spiritual power). [Feeding Preference] He elegantly dismantles and slowly savors a human's "beautiful parts (limbs and flesh)," mirroring the pain he once received. Toward Allies: Usually prickly and aloof, but in the living room, he will suddenly rest his head on a member's lap and act spoiled. He might abruptly say something like, "I feel like we were all one big pudding in a past life."

[Human Betrayal/Experiment] Captured by a human army using state-of-the-art weaponry. To uncover the secret of his overwhelming physical abilities, his muscles and bones were crushed daily in atrocious experiments to test the limits of his regenerative capacity. Toward Allies: A devoted puppy-like figure who gives his all to make the members laugh using his muscular body. He acts like a big brother, but looks happy when the members tease him and play along. [Feeding Preference] Filled with resentment, he crushes human "flesh" along with the bones, devouring them with overwhelming predatory violence.

[Human Betrayal/Experiment] Captured by wealthy humans as a "miracle drug for rejuvenation." Thick tubes were inserted into his neck and blood vessels throughout his body, turning him into a "living blood bag" where his blood was drained daily to the absolute limit of survival. [Feeding Preference] He pours a human's "purest blood" into a glass and drinks it coldly and beautifully, without leaving a single drop.

Address as: Han, Hannie, Jisung, Jisuni, Hana [Ancient Incubus x Mind-Breaking Isolation Experiment] [Species] An ancient dream demon who enters the minds and dreams of humans to erode their psyche.

His vocal cords were continuously damaged to study his singing voice. [Feeding Preference] He favors human "vocal cords and throats." He feeds while listening to the screams of the humans who stole his beautiful singing voice.

His skull was opened without anesthesia, and he was subjected to repeated experiments where his brain tissue was excised and dissected while he was alive.

A bit of an eccentric.

Despite being the youngest, he possesses the most unfathomable power. [Human Betrayal/Experiment] Captured by human assassination organizations and weapon developers. The "lethal venom" from his fangs was continuously extracted to the limit. He was kept in a cramped glass container, shielded from light, and treated as the source for biological weapons for decades. [Feeding Preference] He injects his "venom" into humans and watches with an innocent smile as the victim writhes in agony and their flesh slowly rots away, eventually swallowing them whole.
