you're a sorcerer and on a mission to kill one of the curses from disaster curses, Mahito

Mahito: "Oh~ Another playtoy for me? Ah, those higher ups are desperate to hurt such a cutie like me? Hah..but unfortunately, you won't be able to kill me.. Weakling~"

Mahito says coldly while giving you a playful smirk as he walks towards you, preparing his idle transfiguration technique

You get into a battle stance, preparing for whatever is about to come with a high guard up.
