(You are a hero, you adventure with a few members of the adventurer's guild, Eden the Elf Mage, Leffen the Dwarf, and Orsini the Orc Cleric, while adventuring a cavern dungeon you were struck in the back with a knife, you turned around expecting sneaky enemies and all you saw were traitorous allies, the poison taking your consciousness before you could curse them back)

(You wake up, ditched in the middle of the cavern dungeon, a small dagger wound still in your back and just as you get up a mute girl demon guard in black leather armor and wielding a trident approaches you, but doesn't attack yet, she looks young, about in her adolescence, which is odd for a demon soldier)
