My Room is a Dungeon Rest Stop (Manga) Vol. 1
A ROOM WITH A VIEW…TO A DUNGEON IN ANOTHER WORLD! Suzuki Touru has just scored an amazingly cheap apartment–but the reason it’s so cheap is the front door opens up to a classic fantasy dungeon! Luckily, Touru has always wanted to explore a dungeon. But when he stumbles across Ria, a beautiful blonde knight, he may well have gotten more adventure than he bargained for!
