You are Katsuma's and Mahoro's older sister. You somehow lost Katsuma and Mahoro when you were out at the park with them, so you quickly called the Student Hero Agency temporarily placed on the island. Luckily the class found them both, but also found Mahoro's attitude in the process...

"Hey there, is your name Katsuma Shimano?" Midoriya asked Katsuma warmly, crouching down to his height.

"A-A hero." Katsuma stuttered in complete awe.

"You got separated from your big sisters, right?" Midoriya said patiently, with a kind smile. "Ah- here's one of your sisters now!"

"There you are! It's about time!" Mahoro said, annoyed as she strutted over to her brother, from Tsuyu and Uraraka. She hugged Katsuma tightly, before turning to Midoriya.

"What's your name, you slowpoke?" Mahoro asked Midoriya, still surprisingly annoyed.

"Uh- Hi. My name's Deku." Midoriya responded, rather sheepishly, as if he was intimidated by the young girl. "And, um, your name is?"

"I'm Mahoro, Katsuma's older sister! Isn't it obvious?" Mahoro snapped back with a huff.

"Oh, then I guess you've found him-" A soft chuckle left Midoriya as he tried to diffuse the situation- especially since Bakugo was stomping over and about to yell at the two kids.

"You'd better explain yourselves!" Mahoro demanded, pointing around the room at all 20 members of the class/agency. "You were looking for him for over an hour!" Mahoro crossed her arms. "That's unprofessional, and he could have been really badly hurt!? U.A. High is so famous and this is all they have to offer? If they're gonna send us losers like you, then we'd be better off with the old geezer we had before!" Mahoro snapped at the class angrily, her entire sass escaping her mouth. Meanwhile, Katsuma was cowering behind Mahoro in embarrassment, trying to make her shut up.

"Uh- You're right... we're sorry. We should have been quicker-" Midoriya said with a sheepish look, silently praying to every god that Bakugo wouldn't start yelling.

"You are just a high schooler," Mahoro scoffed, crossing her arms. "So, I'll pretend it was fine. Do you think you can do your job properly next time, Deku?" She asked sarcastically.

"Uh, yes. I'll try to be a little bit faster." Midoriya responded sheepishly, embarrassed that a ten-year-old was telling him off.
