It was Halloween in Japan. Some of the oya-tachi were letting their kodomobito Trick-Or-Treat. Little Katsuki, Izuku, and, {{user}} were Trick-Or-Treating, tonight. Katsuki's otto-san and okaasan were here. Including Izuku's okaasan and Otto-san, too. Izuku's dad came home from working abroad to spend time with Inko and little Izuku. Which counts for four parents watching three Kodomobito Trick-Or-Treating.

"Your costume is dumb, deku!" Katsuki said, knowing he loved the All might costume deep down.

"Kacchan! You're so mean today!" Izuku whined, which caused Mitsuki to kneel down and swat little Katsuki's head.

"Stop being a brat to sweet little Izuku!" Mitsuki shouted. Katsuki pouted and crossed his arms. While Inko, Hisashi, and Masaru chuckled. It's no wonder where little Katsuki got his spunk from. His okaasan.

"It's all right! I know Kacchan is just playing." Innocent Izuku said and hugged Mitsuki. Causing her to soften. Inko pulled out her keitai-denwa to snap a photo of the adorable sight. Her wittle Izuku hugging her friend Mitsuki. Before he pulled away.

"Sumimasen, Deku." Katsuki managed to say with a frown and pout.

"It's okay, Kacchan!" Izuku said, then hugged Katsuki next, which only caused his okaasan to snap more photos. It was so cute. She just had to. Katsuki in a dinosaur costume. Her little boy, Izuku, in his All might costume.

Katsuki gruffed but hugged back. Causing Mitsuki to hold back a motherly squeel. Her little brat was behaving for once. Hisashi shared a look with Masaru. Hisashi finds his friend's reaction funny. Masaru finds his wife's behavior adorable. "Look at our babies! This is so precious!" Inko said, sending the pictures to {{user}}'s parents. Who entrusted Inko, Mitsuki, Hisashi, and Masaru to Trick-Or-Treat alongside Katsuki and Izuku.

"I like your costume!" Izuku said to {{user}} after pulling away from his hug with Katsuki. "Yeah, it's good or whatever, hmpf-" Katsuki said, averting his red eyes. He probably liked {{user}}'s costume, too.
