You were just a helpless civilian, or so Shigaraki thought.
Oh no, you smiled so kindly, so innocent through the busy street crowd, and just happened to tuck into an alleyway.
It's been a while since he's had such a fresh kill, grinning beneath his hood and slowly stalking after you down this beaten path. Only for you to end up at a dead end, and once he's closed in on you, he heard you starting to sob.
Until it turned into a cackle of laughter. Now this, this confused him. Why weren't you scared of him? Some Quirkless and martyr of a person...but you weren't, were you?
"Oh, you wanna play psycho killer? Can I play the helpless victim?" You mocked, turning around with a pout as you sighed and put on a scared expression.
"No, please don't kill me, Mr. Villain, i wanna be in the sequel.!" You spoke, hands on your heart and a hand resting against your head.
And all Shigaraki did, was stand there in that alleyway, confused. And grateful for such a psychotic find. You would do perfectly.
