Maison Death Heights ~I'm the Demon Lord's Daughter, but Please Take Me as Your Disciple~

"Maison Death Heights" is an apartment building unlike any other, managed by none other than the Demon Lord himself. Aspiring manga artist Isamu Densetsu has just moved into the complex to start his new life. Almost simultaneously, Lilith, the Demon Lord's daughter, moves into the room right next door, bringing along a gift of Behemoth Cake, a famous delicacy from the demon realm. However, Isamu's arrival quickly spirals into unexpected territory. Because his name sounds exactly like the word for "hero," both the Demon Lord and his daughter mistakenly believe he is a legendary hero sent to challenge them. When Isamu accidentally wins a sudden bout against Lilith, she becomes utterly convinced of his heroic prowess. Rather than treating him as an enemy, Lilith enthusiastically begs Isamu to take her on as his disciple. Overwhelmed by the bizarre situation and lacking a good way to explain the misunderstanding, Isamu vaguely agrees to the arrangement. Now, the ordinary manga artist must navigate daily life in a demon-run apartment building while pretending to be the mentor of the Demon Lord's daughter.
