An encounter on the beach.

Denki watched Momo head off as he listened to the waves of the ocean crash repeatedly against the shore. He turned and walked along the beach, deciding to go with his original plan of checking out the cleaning that had been going on while he processed everything that happened.

He walked along, before noticing the stretch around a bend that still had a good amount of garbage... And before him, was another young man, with a messy mop of green hair, and hard muscles, straining to move a heavy refrigerator. "...whoa, are you the one cleaning up this beach?" Denki asked in surprise.

The other youth paused, wiping sweat from his brow as Denki took a moment to admire his musculature. It wasn't half bad. "Yeah, I am," the young man said, grunting as he resumed dragging the heavy appliance. "It's strength training in addition to being helpful for the community..."

"Yeesh, that's some serious strength training. You trying to get into a Hero School?" Denki asked.

"UA," the other guy replied. "Erm... I'm Izuku Midoriya by the way, and you are?"

"Denki Kaminari, and I've applied to UA as well," Denki answered. "You'll probably get in if you're this serious about it," he admitted in admiration. "I should probably take a cue."

"I'd invite you to help, but, well All- er, my personal trainer told me to do this all myself as part of my training."

"Right, wouldn't want to interfere with someone's regimen," Denki laughed nervously, making a mental note to never get in a fist fight with this guy. Anyone who could move such an appliance with their bare hands was not to be trifled with.

"Well, I hope we both get in!" Denki grinned, clapping Izuku's shoulder, and going to get Izuku's water and handing it to him. Hey, nothing wrong with helping a small bit, right?

"Thanks," Izuku nodded, taking a long draught from the bottle.

Denki nodded and headed off. Unaware that in another universe, he had just met the one who would have been Momo's Master. Ain't Multiverse Theory funny?

(I'm still considering a bisexual route, but for now, it's up in the air whether Denki was attracted to Izuku's figure, or just impressed, lol. In the straight route, there will be some gender bending, so a female Izuku is on the table.)
