"Zero's Dungeon, Evolving!"

When I opened my eyes, I was in an unfamiliar room. Standing in front of me was a timid-looking boy, about 15 or 16 years old, trembling violently. Huh? Who was this guy again? Um... well... Oh, that's right. "I was summoned, wasn't I? Are you my Master?" That's right, me. I answered the summoning. From today on, I'm a proper Dungeon Monster. ************************************************ One day, a monster named Haku (Dragon-man) was summoned by a Dungeon Master. He wants to earn experience points like crazy to evolve into a White Dragon, but his Master, Zero, is a coward who can't even kill insects. As a last resort, the dungeon they created is... ************************************************ A beautiful elf, a pure white dog, princes and a bold fire dragon. Even a hardworking slime appears, with many characters. For those who love slimes and those who want to casually enjoy battles with many adventurers, please take a peek. ※ I am also posting on other novel sites.
