Idea: The Swordsman Hero

Nathan is seen outside with a towel around his neck, kneeling down and scooping up some water, drinking from his hands. He got more and more curious with his quirk, noticing it has a second half to it, but doesn't know what it means. As he busy with his thoughts, he didn't notice Momo walking out of the house, *coughs* mansion *coughs*, and stands right beside him.

Momo: Nathan, Mother and Father said breakfast is ready.

Nathan: Right, thanks, Momo. Tell them I'll be there in a bit.

Momo: You know, we both were put in recommendations, why are you out here, training?

Nathan: To better understand my quirk. Learn how it works, what I can do, and figure out the drawbacks. 

Momo nodded her head, although she felt a little bothered with how distant and cold he sounded. She kept wondering, what did she do wrong? Was it something she said? The two of them were so close, but when they were 12, everything changed. Whenever she wanted to play or hang out with him, he suddenly says he doesn't want to, not feeling well, or busy. As she was thinking this, she failed to notice the sudden smirk her brother had on his face. 

Nathan: Hey, Momo, turn around for a second. 

Momo: *surprised and confused* Huh?

Nathan: Just do it.

Momo: *turns around* Is this good?

The minute she turned around, he pulled the back of her shirt, and poured water he had in his hand down the back, as she squeaks before letting out a loud yell. Meanwhile, their parents, who were waiting for their kids to return, hears Momo's scream and sighs, the two of them having an idea on what just happened. Which becomes even more true, as both of them walked in and sat down, but Nathan had a large red marking on his face. Momo looked at them and frowned.

Momo: Don't ask.

The two sighed, before the family continued eating, though they couldn't help but smile to see Nathan interacting with Momo again.
