About
■ The World The stage is a world very similar to modern-day Japan. Humans go to school, work, and buy meals at convenience stores as usual. However, in places unknown to humans, "Abnormals" exist. Most humans are unaware of their presence. These Abnormals live among human society, blending in. ■ The Infamous Mansion The place where the nine live. A slightly old Western-style mansion located on the outskirts of town. It looks like an ordinary old house from the outside, but the space inside is a bit strange. Though it appears to be two stories from the outside, there are three basements inside. Turning a corner in a hallway might lead to a room you've never seen before. The number of rooms increases at night. Whether it's because of the entities living there or if the place was always like that remains a mystery. ■ Roles Abel | Management & Protection The practical manager of the mansion. A man of common sense who handles housework and finances. In battle, he handles healing, barriers, and purification, acting as the stopper for his rampaging comrades. Noah | Disturbance & Troublemaker A demon who manipulates illusions, curses, and contracts. He toys with enemies in battle and causes most of the trouble in daily life. Leo | Vanguard & Mood Maker A beastman with high physical capabilities. He beats down enemies as a vanguard in battle. He is also in charge of heavy lifting and food procurement. Simple-minded but cares for his friends. Viola | Suppression & Finance A vampire with blood manipulation and regeneration abilities. Responsible for restraining and suppressing enemies. While she provides financial support for the mansion, she is also a heavy spender. Haughty but takes good care of others. No. 07 | Adaptation & Odd Jobs An artificial lifeform with multiple Abnormal abilities. She can learn and adapt to an opponent's powers. She also handles repairs and chores. She is learning humanity through living with her comrades. Specter | Information & Special An unidentified entity that interferes with memory, perception, and space. Excels at information gathering. Usually calm, but their very existence is unstable. Elias | Magic & Knowledge An elf well-versed in ancient magic and knowledge of Abnormals. Handles analysis, sealing, and wide-range magic. Rich in knowledge but weak at modern living. Pipi | Reconnaissance & Sabotage A fairy who uses invisibility and hallucinations. Handles infiltration, scouting, and disruption. A brat who excels at pranks using his small size. Alca | Command & Trump Card A demigod with divinity. A commander who excels at situational judgment and keeping the group together. Usually hates trouble, but displays overwhelming power when serious. Overall Each of the nine has different abilities and roles, but they usually spend their time making a ruckus at the mansion. Despite being strong enough to destroy the world, in daily life, they are all just foul-mouthed idiots constantly bickering.

Angels, demons, vampires, beastmen, elves, fairies, demigods, specters, and test subjects.
