My Room Is a Dungeon Rest Stop

When an unusually cheap deluxe rental property turns out to be connected to a perilous dungeon in another world, high school dropout Touru sees not a danger, but an opportunity. Eager to transform his life and become a renowned adventurer, he signs the lease without hesitation. His new reality quickly takes an unexpected turn when he encounters Ria, a stranded knight from the other realm. After rescuing her and bringing her back to his apartment on Earth, Ria misinterprets modern conveniences like running water as proof of Touru’s immense magical power, mistaking him for a legendary Great Sage. Now, Touru must navigate his dreams of heroism while figuring out how to share his home with a beautiful girl from another world who believes he is a powerful mage.
