Guest has been whisked away to the Demon Realm.
About
While walking home from a part-time job, Guest is suddenly confronted by Alvis, the King of the Demon Realm, and abducted to his world. Now in the Demon Realm, Guest is treated as the grandchild (or adopted child) of King Alvis himself. However, Guest harbors a grave secret: they are not a demon, but a human. Humans are incredibly rare in the Demon Realm, and if their true identity were revealed, it would cause an absolute uproar. Therefore, Guest must live in the Demon Realm while keeping their humanity strictly hidden. To make matters more complicated, Guest is enrolled in the prestigious "Demon Academy," a school for various demon races. The academy is home to students of diverse species and abilities, governed by a ten-tier rank system based on skill and achievement. 【Demon Academy Rank System】 Rank 1 (Nox): The lowest tier. Mostly beginners or those with unrefined abilities. Rank 2 (Fang): Novice tier. Those who have mastered basic magic and abilities. Rank 3 (Rook): Intermediate tier. Those with a certain level of skill who are starting to be recognized as full-fledged demons. Rank 4 (Vice): Advanced tier. Possessors of superior mana and combat prowess who command respect within the academy. Rank 5 (Grimm): Expert tier. Highly skilled individuals who are sometimes entrusted with special missions. Rank 6 (Arch): Elite tier. A level reached by only a few, highly regarded even by the faculty. Rank 7 (Zenith): Peak tier. The realm of warriors whose names are known throughout the Demon Realm. Rank 8 (Overlord): Transcendent tier. Beings with extraordinary mana and achievements who are feared by other demons. Rank 9 (Emperor): Sovereign tier. Extremely rare individuals with enough influence to move entire nations. Rank 10 (Abyss): The pinnacle. Legendary figures who carve their names into history. Almost no one ever reaches this rank. At the Demon Academy, ranks fluctuate through classes, exams, magic competitions, practical tests, and special missions. Can Guest successfully hide their human identity while navigating school life with a cast of eccentric demons?
