Izumi Midoriya was so excited to return home from her day at school. It had been a very good day for her. Her class had recently taken a big test and today had been the day they had all received the results. The young green haired girl had gotten the highest score out of all her classmates. And so she was on her way back home, her head held high, anxious to show her mother and her older brother her score.

Once the apartment buildings were in her sight she kicked off in a mad dash to reach them. She took the steps two at a time and by the time she was in front of her door she was out of breath, though she paid little mind to her aching legs as she turned the key on the knob. The door flew open and she called out, "I'm home!"

Izumi heard a startled squeak from the kitchen as she toed off her shoes before the soft tone of her mother called back, "Welcome home Izumi! Goodness, you startled me." The young girl put her shoes on the rack and raced to the kitchen opening up her school bag to retrieve the test paper.

"Mama, mama, look look look! Look what I got!"

Inko turned to look at what her daughter was so frantic about. The freckled girl, her deep green eyes sparkling with anticipation, held out a paper for her to take. The older woman wiped her hands down on the apron she had on and took the paper, "Let's see..."

She scanned the paper, quickly settling on the bright red mark that was at the top of the page. Izumi was met with a large smile from her mother, "A hundred percent! That's wonderful Izumi!"

The woman enveloped her child in a warm hug, "I'm so proud of you Izumi." The girl returned the embrace, her heart filled with warmth at her mother's words, "I was the only one to get a hundred, Mama! I was top of the class."

Inko ruffled her hair, "That's my girl. How about a reward? Since you did so well on your test."

She nodded eagerly. Inko tapped her chin in thought before her eyes lit up, "How about you choose tonights dinner?"

The little girl squealed in delight before raising her hands in celebration, "Katsudon!"

Inko giggled as Izumi started to run around the kitchen table chanting, "Katsudon! Katsudon! Katsudon!"

She scooped up the girl as she was about to make her third round, "Okay little one. First, you have to finish up any homework you have."

Izumi saluted her mother, determination set in her eyes, "O-K!"

Once Inko set her down, Izumi placed her backpack on the kitchen table and took out her school work. After a few moments of setting up, her head shot up in realization, "Mama, is big brother home?"

Inko looked back at her before turning her eyes to the clock on the wall, "Not yet, he should be home soon sweetheart, don't worry."

The girl, though a little disappointed that she couldn't show her brother her work in that moment, nodded and set to work on her homework.

A good fifteen minutes into her school work, the front door opened and a tired but gentle "I'm home" sounded from the entryway. At the words, Izumi's head turned sharply toward the front door before she scrambled to get out of the chair. Inko responded with a soft welcome to her son, chuckling as she heard her daughter run toward her brother.

"Izuku, Izuku!" called little Izumi. The curly haired boy looked up from untying his shoes at the call of his little sister. She launched herself at him at the last moment. Izuku, having dealt with her greetings from the time since she first learned how to run, was ready and immediately caught her. The young hero in training, though slightly exhausted from his day at school, couldn't help the smile that formed on his face. His little sister was one of the lights of his life. He couldn't imagine himself without her. Her little arms wound around his neck in a tight hug. Izuku twirled her around once, a squeal of joy erupting from her mouth as he squeezed her back, "I'm home Izumi."

The little girl smiled widely as she snuggled her face into her brother's neck, "Welcome home big brother."

He set her down on the step above the genkan and quickly took off his remaining shoe before putting them away. Izumi impatiently waited for him to finish before immediately yanking his hand away from the shoes and toward the kitchen. "Whoa, Izumi, what's the rush?"

"Look look look Izuku!" She handed him the test as soon as she reached the table.

Inko walked up to her children, "Your sister scored the highest in her class you know?"

Izuku scanned the page, a huge smile forming on his lips. His eyes went back toward his sister who was biting her lips nervously, awaiting his reaction. "You're amazing Izumi," he lifted her in his arms before setting her on his hip, "You really gave it your all, didn't you?"

He was rewarded with a bright smile and rosy cheeks as she nodded, "I went Plus Ultra big brother! Just like you would!"

Izuku could feel his heart melt at her words and smile. He hugged her tightly and pressed a kiss on her heated cheek, "I'm really proud of you Izumi! What should we do to celebrate?"

Inko, who had gone back to preparing dinner, called out to him from her spot at the counter, "Well Izumi got to choose tonights dinner for her hard work."

Izuku looked at the little girl. She grinned widely and whispered, "Katsudoooon!"

The messy haired boy laughed and set her down once more, "Then how about, the next time we go out, I'll buy you whatever toy you want?"

Izumi's eyes lit up at the proposal, "Really?"

He nodded, "Of course!"

The young girl squealed in utter delight and jumped up and down, "Yes yes yes yes YES!"

That night Izumi slept with a warm stomach full of her favorite dish and the prospect of a new toy to add to her collection. It had been a very good day indeed.

AN: This idea hit me just last night. The thought of Izuku having a little sister that idolizes him just as he does with All Might melted my heart to bits. I plan on writing some other one-shots with Izumi, especially her extreme dislike of Bakugou and the time she gets her quirk. Thank you very much for reading. Leave a review with your thoughts and maybe other scenarios you'd like to see in the future?
