The hell happened to the bro? Dashed through the guys even though he was the slowest runner and told them to back off for once.
Very cute end, nice to see some affection from him.
Glasses most times makes people look "book worm/ nerdy" (actually a meme from long ago)
Also, the bro activated his hidden abilities, he looked weak before because he was a easily bullied book worm type of guy, so he never believed he had good physicals.
Hmm... I thought Japanese more modest with their clothing except when in pool or local festival. But here we see Maria wearing clothes that exposed her navel in public without shy. I'm confused.
The glasses must be some kind of power limiter tool. He dashed through like a madman after he took those off. Now we know Maria is not the only one with superhuman power in the family.
