The morning started like any other in the Aizawa household: chaotic. Souto stomped into the kitchen in his pajamas, rubbing sleep out of his eyes as he searched for his usual bowl of cereal. The house was still quiet—Hizashi was still asleep to blast his morning playlist, and Aizawa had already slipped out.
Shinso, was enjoying the rare calm when he opened the fridge for milk… and found it.
“What the—?!” Shinso recoiled, holding up a leaky blood bag between two fingers like it was radioactive waste.
“SOUTO!”
Souto, who had just grabbed the cereal box, turned to see Shinso standing there with the incriminating evidence. A wicked grin spread across his face.
“What?” he said innocently, leaning against the counter. “You afraid of a little blood, big brother?”
Shinso glared, holding the dripping bag up like it was Exhibit A in a court case. “Stop leaving your gross blood bags in the fridge! This thing’s leaking all over my leftovers!”
Souto shrugged, completely unfazed. “Well, don’t touch it, then. It’s my food.”
“It’s not food! It’s—ugh, do you know how disgusting this is?!” Shinso tossed the bag into the sink and turned on the water, muttering under his breath as he scrubbed his hands.
Souto’s grin only widened. “What’s the matter, Hitoshi? Scared?”
“I’m scared I’ll get a disease!” Shinso shot back, slamming the faucet off.
“Oh, please. It’s clean blood,” Souto said, rolling his eyes as if that made it any less gross.
Shinso grabbed a towel to dry his hands, his calm demeanor fraying with every passing second. “You can’t just leave blood bags lying around like some kind of—some kind of vampire raccoon!”
That one hit a nerve. Souto narrowed his eyes, baring his tiny fangs. “Did you just call me a raccoon?”
“Yeah, I did,” Shinso said flatly, arms crossed. “What are you gonna do about it?”
For a moment, it seemed like Souto might leap across the kitchen table and tackle him. But instead, Souto’s lips curved into a devilish smirk.
“You know,” Souto said, his voice dripping with mischief, “I bet you’d look really cool with fangs. Wanna see how it feels?”
“Don’t you dare—” Shinso didn’t even get to finish his sentence before Souto lunged at him, fangs bared and hands outstretched.
“GET OFF ME, YOU LITTLE GREMLIN!” Shinso yelled, trying to keep Souto’s teeth away from his arm as the smaller boy clung to him like a rabid squirrel.
“Stay still, I just wanna see something!” Souto cackled, his feet scrambling for leverage as he attempted to sink his fangs into Shinso’s shoulder.
The kitchen turned into a war zone. Shinso grabbed a spatula to fend off the attack, while Souto dodged and weaved like he was playing a game. Cereal spilled everywhere, chairs were knocked over, and the fridge door was left wide open.
“YOU’RE INSANE!” Shinso shouted, finally managing to pin Souto to the wall.
“And you’re boring!” Souto shot back, wriggling like a fish on a hook.
“Boring is better than being a feral child!”
“TAKE THAT BACK!”
Their yelling echoed through the house, waking Hizashi from his rare morning nap. The blond stumbled into the kitchen, hair a mess and slippers half on.
“Okay, okay, what’s going on in here?” Hizashi asked, holding up his hands like a referee.
Shinso, panting and disheveled, pointed at Souto. “He’s trying to bite me!”
“Am not!” Souto shouted back, still dangling from Shinso’s grip.
Hizashi raised an eyebrow. “Souto, you literally have bite marks on your pillowcases. Don’t lie to me.”
Souto pouted, crossing his arms. “He started it. Called me a raccoon.”
“Did you?” Hizashi turned to Shinso.
“Well… yeah, but—”
“Apologize,” Hizashi said firmly, like a parent defusing a playground fight.
Shinso groaned but muttered an apology but so did Souto.
By the time Aizawa returned home later that afternoon, the kitchen was spotless, and the two boys were sitting on opposite ends of the couch, pretending they weren’t just mortal enemies a few hours ago.
Aizawa stepped inside, dropping his bag by the door. “Why does it smell like bleach in here?”
“No reason,” Hizashi said quickly, shooting the boys a warning glance.
Aizawa didn’t look convinced, but he was too tired to dig into it. “Whatever. Dinner out tonight.”
As soon as Aizawa disappeared down the hall, Souto leaned over to Shinso, smirking.
“Round two later?”
Shinso gave him a look that could’ve curdled milk. “If you so much as look at me with those fangs again, I’m locking you in the basement.”
“You wouldn’t,” Souto said, narrowing his eyes.
“Try me,” Shinso shot back.
