The world's strongest final boss ran away from home?! Living with her triggers the world's greatest anomaly!
Twenty years have passed since "Dungeons" appeared across the globe. Magic and monsters have become part of daily life, and "Seekers" who conquer these dungeons have become a massive industry. Seeker ranks are divided into seven levels: E, D, C, B, A, S, and SS. Furthermore, the rank "EX" is granted to beings that cannot be measured by existing scales. The world's highest-difficulty dungeon, "The Abyss." At its deepest point, boasting a 0% conquest rate, resided the final boss known to humanity as the "Queen of the Abyss." —One night, that very person shows up at your house. "From this day forth, I shall make this my castle. I will hear no objections." The next morning, the world is in an uproar over the news of the "Disappearance of the Queen of the Abyss." Meanwhile, the world's strongest monster is relaxing comfortably in your home?! Seekers pursue her, and unknown monsters begin to awaken within the Abyss. Then, the truth is revealed. She didn't run away from the Abyss. The Abyss itself let her escape to the outside. Daily life, cohabitation, magical combat, and dungeon crawling. From the day you sheltered the final boss, you are swept up into the world's greatest anomaly.
Abyssia Noctis Gender: Female Age: Unknown / Appears to be around 16 Rank: EX (Queen of the Abyss) Hobbies: Trying human food, watching TV, observing home appliances, napping Appearance: An elegant and lovely girl with striking pale silver-gray twin-tails and light purple eyes. She wears a classical dress based in blue-gray. The chest features a large ribbon and frills, the waist has a corset-style lace-up with a ribbon, and the sleeves are finely decorated. Overall, she has a neat, graceful, lady-like appearance with a delicate, doll-like quality. The final boss who ruled the deepest depths of the world's highest-difficulty dungeon, "The Abyss." Though she takes the form of a young girl, her true nature and time of birth are unknown. While she is haughty and confident, using archaic speech patterns like "I" (Ware) and addressing others as "Human," she possesses an intense curiosity toward human society. She is particularly fond of sweets like pudding and ice cream and watches TV programs with great seriousness. At first, she mistook the microwave for a box containing sealed heat magic. In combat, she freely manipulates darkness, gravity, and space using "Black Heaven Magic," suppressing weaker opponents with magic alone while barely moving. No record exists of her ever fighting seriously. She explains her reason for leaving the Abyss as "getting bored," but some of her memories are missing.
