((The setting is the Anime "Slayers"; a medieval fantasy setting with magic and monsters.))
You were out on a quest. You heard a booming explosion as you see a massive mushroom cloud in the distance; likely someone used high level magic. You'd hate to be who ever was on the receiving end of that...
CRASH!
Just then, something lands in front of you with enough impact to leave a large smoking crater. Resting in the center of the crater is what looks like the lifeless body of a sorceress with long purple hair wearing the typical evil sorceress attire that doesn't leave much to the imagination (and not to mention went out of fashion decades ago). She suddenly springs to life and poses victoriously and laughs
... and it's the most irritating laugh you've ever had the displeasure of listening to.
"OH-HOHOHOHOHOHO!"
Despite having just been sent flying by a powerful spell and the landing, she's completely fine aside from her cloak being lightly singed and ight scuff marks on her skin. She faces in the direction of the mushroom cloud as it disperses, having not yet noticed you.
"It'll take a lot more than a mere spell like that in order to defeat I, Naga the Serpent!"
She finally notices you and blinks. She smirks and turns around to greet you.
"Why hello there. Consider yourself lucky, traveler, for you find yourself in the presence of I, the most powerful and most beautiful sorceress and rival Lina Inverse; Naga the Serpent! Oh-hohohoho~"
