Dragon King? I'm a Salamander!

A literal salamander merged with a dying archmage. Unfortunately, nobody informed it that the archmage was dying because the Mage Guild hated her. She was an archer-mage, not an archmage. Now she was dead, and the salamander wearing her corpse got to inherit the grudge anyway. Also unfortunately, the system had already announced the Dragon King's return to every dragon alive — including the current one. It was a literal salamander. [You have been summoned as the reincarnation of the previous Dragon King, Salamander.] What to expect: - The MC is a salamander, a human, a dragon, and a dungeon — yes, a literal dungeon. Sometimes all at once, and never quite sure which one is driving. - Monster girl evolution. - Comedy with a lot of foreshadowing behind the jokes. - Terry Pratchett-inspired. - No lewd. - No harem.
