Work Text:
Izuku was so bored; Not even doom-scrolling sounded fun. He was playing online chess with Nedzu, but he had to go help some dumb business course teacher. Seriously, he even searched "things to do as an unemployed 15-year-old who's already graduated high school and has 2 bachelor's, 3 master's, and 1 doctoral degree, no glue no borax" on Pinterest, and the only results were dumb and boring. Like obviously he already thought about watching a movie or baking, he like wanted something actually fun like a new way to annoy his dad, or like a little craft to give his Papa. Wait, go back. Annoying his dad! Sometimes his genius is just too much. Izuku scrambled to find his phone to call Nedzu. After given the go-ahead Izuku snickers as he puts on his vigilante gear.
Aizawa Shota was watching his students work on the assignment he had just given when he felt the air shift as the door opened, his son sauntering in, full gear and everything, holding a paper bag and 3 coffee cups from his favorite cafe. The one with weird hours, that's in a completely different city that takes an hour to get there by rooftop. Has he said how much he loves his son? He scans the room none of his students seem to notice the new presence in the room too engrossed in their assignments, which really, was very disappointing. He would have to work on situational awareness with them. Shota hugged Izuku once he was close enough, planting a small kiss on his head. It's okay as long the students don't see. Izuku nuzzled into the hug for a little, before pulling back and handing Shota two coffees, one black and one overloaded with sugar, so sweet even Nemuri couldn't stomach more than half without getting sugared out. He thought that would be all and his son would leave, but oh, how wrong he was. He started a sign conversation with Shota, which was lovely, and Shota loved that he got to talk to his baby earlier than normal. No, what was bad was when Shinsou looked up, question on his tongue before his eyes widened as he spotted Izuku. A sly grin slid on his face as he said in a bored tone "Why is there a deadly Vigilante here sensei?" That little shit. Sero looked up from his paper to Shinsou raising an eyebrow "Deadly vigilant in a hero school? What are you smok- HOL-HOLY SHIT THERE'S A DEADLY VIGILANTE IN THE ROOM" Everyone's heads whipped up eyes narrowing in on Izuku. Shota sighs, Izukus spins around facing the empty wall pretending to be alarmed exclaiming "Vigilante? Where!?" Shota just knows he has a shit-eating grin on his face under the mask. Shota pinches the bridge of his nose "Should've known you had alternate motives, Problem Kit." Aizawa groaned "Well, introduce yourself." "Hello class 1-A! You probably know me as Viper!"
"What the hell is a dumb vigilante doing here." Bakugou sneered
"Incorrect! I am, in fact, not a vigilante," Izuku states cheerily
"WHAT THE HELL YOU JUST SAY?! YOU TRYING SAY I'M DUMB?!"
"Wow. Um ok, that's like textbook superiority complex right there."
"WHY YOU FUC-" Bakugou growled before Seros tape got smacked over his mouth.
"What!? you're a pro? Everyone online says that you're a vigilante." Kirishima says genuinely curious
"Nope neither. Technically I am just a civilian who has to use self-defense on the regular."
"Why's that?" Jirou asked
"Cuz" Izuku Shrugged "You need a quirk in both instances, however, I do not possess one; so RIP to social life, "omg it's alive" to not quite crime, crime life, I guess."
"Oh, that makes sense, "Jirou says
The class erupted, yelling their thoughts out some kind some not, Shota glared, and the room fell into silence again before Denki spoke up,
"I'm kinda surprised Iida wasn't scolding Viper when we thought he was breaking the law."
"Iida? Why would he scold me?"
"Well, he's kinda uptight about the rules." Denki scratched the back of his neck. Izuku started crackling as Iida turned red.
"Oh, man. Iida. Uptight. About rules." Izuku wheezed but slowly stopped laughing "Oh damn, you're serious." Izuku Just laughs harder. Ok, Shota changed his mind he is 100% ok with Izuku staying to finally expose his nephew so he'll stop revenge teacher petting. Man, that's such a weird thing to say Shota realizes.
"Zukuuu Stop it" Iida drags out his, head in his hand's ears red.
"Oh my god! I didn't believe him, I am so telling your brother Ten-ten"
"wait, Ten-ten? Zuku? You know him out of costume Iida??" Mina chimes
"That's so manly. what's he like?" Kirishima said wiping away invisible tears.
"Well, this is my cue," Izuku said mock saluting as he walked out the door. Before he popped right back in.
"Wait, Dad, I actually came here for a reason, do you know where Papa's Curling iron is?"
Shota sighed knowing each word was picked to give him as many questions as possible. "One: You didn't come here just to ask that, don't lie to me. Two: Did you check the third down drawer closest to the right sink in our bathroom, Three: Why the hell are you curling your hair? It's already curly." Izuku scoffed as if Shota said something so stupid it offended him.
"It's different. You just don't get it." Izuku upturned his nose, light glinting off his mask before he dropped the act. "Thank you, Dad, Love you, see you tonight."
"Bye, sweetheart. Be careful not to slip off any roofs, and stop by your Papa's class or he'll have both our heads."
"K" and then the door was shut.
The class once again erupted into yelling.
