What's Her Quirk?!

Alternate: Izuku

"What?! No way, were you that much a fan of Papa?" I asked, laughing a little.
"I have every bit of All Might merch I could get my hands on! I'm still a huge fan of your dad!" Izuku said, laughing too, we were just having fun at my house, we'd trained together in my backyard earlier but we were taking a break to re-hydrate and have a snack. "You should come over and see me room sometime."
"Oh my gosh, lemme guess; posters on every wall, figurines filling shelves, All Might sheets. How close am I?" I asked with a giggle.
Izuku blushed a little, clearly becoming a little embarrassed, "Yep, all that and more," he said.
"You're the biggest fanboy ever, Izuku, it's so cute!" I giggled then stood up and stretched a little, having too much energy to sit for much longer, I had to stand.
"Oh, are you ready to get back to training?" he asked, standing up too.
"Sure, I was just standing up to stretch but I think we've taken enough of a break, time to get back to training!" I cheered and hurried back outside with Izuku right behind me.

Izuku watched me as I hurried over to one of the pull up bars, I had to jump to reach it but I didn't care or mind, I just started doing pull ups while he watched over me and counted under his breath.

"So, uff, have you always muttered like that? Hah. Or was it something you learned subconsciously?" I asked.
"Huh? Oh, I-I think it's something I've always done ever since I was a kid," Izuku said, "Kacchan thinks it's really annoying and yells at me whenever I do it around him."
"Well, nnf, Bakugou is a little bit of a jerk, I think the muttering, ngh, is kind of endearing in a way," I pulled myself all the way up then hooked my legs over the bar and sat on it, breathing hard, "It's just something kind of unique to you and it tells everyone when you're deep in thought about something, mostly it's strategy."
Izuku's face was bright red as he tried to hide it by looking away and rubbing the back of his head, his arm partially hiding his face from my view as he laughed nervously.
"It's really not all that endearing, I've given my strategy away a couple times by doing that and almost let slip All Might's secret a couple times, even your secret too," he started muttering, "I-I mean it's not like I realize I'm doing it, like you said, I get deep in thought and kind of zone out. I don't realize I'm saying stuff out loud when I'm like that and so I suppose it kind of puts me at a disadvantage sometimes, I should try and learn not to mutter so much or in the future I might accidentally give away my plan if a villain is eavesdropping and hears me strategize out loud like I tend to do..."

He continued muttering so I giggled and hopped down, striding over to grab his free hand, "Izuku~."
He was startled out of his muttering, "Oh! I was just doing it wasn't I? I'm so sorry," he apologized before noticing I'm holding his hand, "Gah! You're holding my hand!"
I giggled, "I am, I was thinking, maybe we could go someplace and talk about how I turned invisible that one time? Try and figure out how I did it?"
"Y-You mean like a date?!" Izuku seemed just a bit overwhelmed.
I blushed, "I-...Well, we could make it one, i-if you wanted."
He suddenly held my hands between his, our hands were quite sweaty even though I'd been the one just working out. "Yes! I would very much like that!" he said as he bowed which made me start laughing again, he was so cute.
