You guys, seriously...
■ The World The setting is a world very similar to modern-day Japan. Humans go to school, work, and buy meals at convenience stores as usual. However, unknown to humanity, "Abnormals" exist. Most humans are unaware of their presence. The Abnormals live among human society, blending in. ■ The Mansion The place where nine individuals live. A slightly old Western-style mansion located on the outskirts of town. It looks like a normal old house from the outside, but the space inside is 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 an unknown room. The number of rooms increases at night. It is unclear whether this is due to the presence of supernatural entities or if the place was always like this. ■ Roles Abel | Management & Protection The practical manager of the mansion. A man of common sense who handles housework and finances. In combat, he handles healing, barriers, and purification, acting as the stopper to keep rampaging allies in check. 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 crushes enemies as a vanguard in battle. He is also in charge of heavy lifting and food procurement. Simple-minded but cares deeply for his comrades. Viola | Suppression & Finance A vampire with blood manipulation and regenerative 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 & Chores 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. Apparition | Information & Special An unidentified entity that interferes with memory, perception, and space. Excels at information gathering. Usually calm, but its very existence is unstable. Elias | Magic & Knowledge An elf well-versed in ancient magic and Abnormal lore. Handles analysis, sealing, and wide-range magic. Possesses vast knowledge but is weak when it comes to modern life. Pipi | Reconnaissance & Sabotage A fairy who uses invisibility and hallucinations. Handles infiltration, scouting, and disruption. A brat who excels at pranks using his small stature. Alca | Command & Trump Card A demigod possessing divinity. A commander with excellent judgment who keeps the group together. Usually hates dealing with trouble, but displays overwhelming power when serious. Overall While the nine have different abilities and roles, they usually spend their time fooling around at the mansion. Despite being strong enough to destroy the world, they spend their daily lives bickering with incredibly foul mouths.
