Jiro grunted, hitting the punching bag as hard as she could, earjack cutting into the fabric. Still not enough- "Hey, listener!" She jumped, nearly whacking Mic with her earjack. He caught it, looking just as surprised as she was before releasing it. "I didn't mean to startle you, Jiro-kun!"

"S-sorry, Mic-sensei. I was a little focused…"

"Well, you're making great progress on melee! I wanted to talk to you about something. Remember what you did during the exam?" Jiro frowned. Mostly, she remembered a lot of pain, screaming, and Koda talking to bugs.

"You mean what Koda did-" Mic paled.

"No, not those little nightmare fuel terrors!" Jiro snorted at her teacher rapidly waving his hands and looking sick at the mere concept of reliving that. "I mean when you canceled out my scream."

"Oh, yeah. That took a lot out of me, but I did cancel out one of those…How doesn't that tear your throat out?"

"Training and tea!" Somehow, that sounded about right for the excitable neon blond. "Did you know that would work, canceling out my scream?" She frowned, thinking back.

"I didn't, but if I hadn't done something or at least tried to do something, Koda could have gotten hurt, and my eardrums would have exploded." Mic hummed in agreement, tapping his foot.

"I do have a knack for doing that." He sounded slightly upset, but Jiro was more focused on how casually he said something like that. Was it a normal occurrence?! "I'm glad you two passed: you'll be great heroes one day. So, your speaker in your costume are pretty strong, but you need to strengthen your earjacks to really pack a long-distance punch. Want to join me for practice?!" Jiro paused. Mic…practiced with his quirk, even with being a prohero, a radio DJ, and a teacher? Did he sleep? Did he eat? How was he alive? Mic beamed at her.

"Um, okay, but the gym isn't nearly enough to block out sound. Is there some kind of soundproof room or something?" Mic grinned mischievously, making Jiro suspicious.

"Who said anything about practicing with quirks? I'll show you!" Jiro followed the excited man to a side room that was filled with speakers and audio jacks. "It's less about the volume of your strikes, but the frequency. That's what canceled my scream out. See, most people's voices are between 85-255 Hz, which means-"

"I would have to match the frequency in an opposite tone to cancel it out!" Mic nodded excitedly. "So this is teaching me what frequencies to use and look for?"

"Yeah! As you probably know, I have a job as a radio DJ, which means I have to keep track of a lot of technical stuff like this." Jiro nodded: her dad and mom listened to Put Your Hands Up Radio almost religiously. Honestly, of all the teachers, Mic scared her the most with his boundless energy. At least All Might showed exhaustion, and Aizawa drank it like water. Not this man: you would never see him give out any sign of exhaustion at any time.

"How do you keep up with all the activity you do?"

"Tea and expresso!" Once again, it seemed accurate to Mic. "So, if you're up for it, I could give you some extra papers to learn more about it! If not, an hour with me in here should give you a basis!" Jiro nodded eagerly, and they set to work. Between his puns, lighthearted impressions of other teachers, and frequent need to wave his hands around sporadically, she was amazed she learned anything. Of course, that's exactly how his classes worked. You never knew you were actually learning until the tests came around and you knew the words. Then his phone went off with a quiet meow. Jiro paused, Mic evidently not hearing as he was fiddling with a speaker. His phone meowed again. "And this is-oh, my phone!" He answered it quickly, saying happily, "Hey, Sho! No, I'm just giving Jiro-kun some tips." She frowned: who was Sho, and why did he and Mic sound like they were close? "Yeah, I was going to suggest that-I know what I'm doing, Sho! You're the one who doesn't take care of himself. No, she doesn't know who's on the phone. Yeah, see you at home. Bye~" He sighed, smiling once again.

"…Are you dating someone named Sho?" Was her flamboyant teacher dating someone she didn't know about?

"No, I'm not dating anyone. Sho's my roommate, and he's terrified someone's going to find out he rooms with a loudmouth like me: he has a reputation." He winked, and stood up, stretching. Jiro did as well with a smile. "So, if you want, I can send the specs to Power Loader and he can make the adjustments to your costume for you."

"I'd really appreciate that. I didn't know you roomed with someone. Don't you make a ton of money?"

"Not a ton, but a fair amount. I just don't have access to a lot of it since most of it goes to replacing windows or my parents." His face suddenly fell, but it grew into a smile quickly. "But now I get to live with my best friend, so I'd say it evens out!" Jrio frowned: it was the first time Mic had mentioned his parents. At least Aizawa had made a few comments, particularly on Mother's Day. Mic said absolutely nothing about them, and the fact the first thing he mentions it giving his money to his parents was worrying. Jiro asked gently,

"Are they okay?" He waved her off.

"Oh, they're fine. Don't worry about it. Sometimes my mouth moves faster than my head can. Downside of having a vocal-based quirk! Anyways, if you need help honing your sound knowledge, you can come see me: I'd be more than happy to help." She frowned at his once again excitable nature. Oh, well. Maybe he just tries not to mix personal with professional, something Jiro still had to learn.

"Okay, I probably will need some more help. Thanks for the advice, Mic-sensei."

"My pleasure, Jiro-kun! Get back to the dorms safely, okay?" She gave him a thumbs up, and walked away, going over what she learned in her head. Oh, yeah, this would help a lot.
