It actually all started as a joke. A guy who’d had too much to drink wasn’t paying attention, and tripped over something. Sora, heroic reflexes kicking in, lunged forward to catch the guy before he hit his head, essentially saving him from his own stupidity. What was impressive was that the guy was about a foot taller than him and obviously bigger, yet Sora hoisted him back to his feet without a sweat.
“Man, you’re stronger than you look!” The guy laughed. “How much you bench!?”
Sora grimaced. “Uuuuuuh...” he wracked his brain, trying to think of what was normal for human standards. “50 kilograms?” He offered hopefully.
“No way, you’re lying! It’s gotta be more than that!”
And thus started an impromptu arm wrestling match to see who was stronger. The prize? Bragging rights. It just went downhill from there.
Sora had beat two guys already, and the handful of men and women cheering them on was nice. This third guy he was trying to beat though… would probably have to be the winner. He was tall, and his arms were twice as big as his. He worked construction so had some good mass to him. By human standards… he would have beat Sora easily. So the young dhampire-disguised-as-a-human was already throwing the match, letting the big, burly man push his arm back a few inches to get ready for the final, epic slam. (Not without an impressive show of fake strain on Sora’s end, mind.)
“What are ya even doing in here, kiddo?” His opponent joked. “This place is for grown ups!” He jabbed, making some onlookers laugh, and others “ooooooooh” to goad him.
...Unfortunately Sora was very competitive, and he hated being called a “kid” more than anything. “I’m 21, dammit! I'm not a kid!”
So he beat him. All but slamming his hand into the table.
