They were walking through the hall Eri holding Mirio's uniform jacket when a boy walked out and asked, "Hey Mirio is that your kid?" Mirio just stopped and stared blankly at him. "T-that's not really your kid is it?" He asked warily.
Mirio just stared for a bit before laughing. "No, she's not my kid." The boy sighed in relief before Mirio added "Maybe." and walked off. They made their way over to where Tamaki and Nejire were waiting.
"Hey, Mir- why are you with child?" Nejire asks looking between him and the little girl who is barely visible from where she's hiding behind him. "This is Eri. Eri this is Nejire and Tamaki." Mirio says pointing them out. Tamaki just waved nervously.
"Mirio why didn't you tell me you brought a child to school!" Nejire yelled. Eri flinched at the sounds. "That's not yours right?" Tamaki asked quietly "No." Mirio laughs at the way both Nejire and Tamaki visibly relax.
Nejire continued to yell voice getting louder and louder in Eri's head as the time passed. Eri didn't know what she was saying flashes of Overhaul yelling crossed her mind. He told her such mean things when he got mad (and he was almost always mad). Called her useless, worthless, said she didn't deserve to be alive, that she was a monster.
Before she knew it tears were running down her face. "O- hey Eri what's wrong?" Mirio asked worriedly picking her up. "T-the yelling made m-me th-th-think about him y-yelling at me." She whispered out sniffling. Mirio rubbed her back whispering comforting words as she cried. "Shh, It's okay he can't hurt you anymore."
Nejire and Tamaki were having silent panics but that's not what we're talking about.
Mirio continued to comfort Eri until she was calmer. Her eyes were still watery, face tear-stained, and a little snotty. But calmer none the less. "Eri I am so so sorry for yelling," Nejire said making sure her voice was quiet.
"It's okay," Eri whispered. "You didn't mean it." She smiled slightly, it looked less forced than the last time (but still forced).
"Now Nejire if you want to ask questions please speak like a normal person." Mirio's tone was teasing but also very serious. Nejire nods her head. "Right, yes of course." She said uncharacteristically nervous (it seemed more like Tamaki than her).
Nejire asked the obvious questions. Where did she come from, why do you have her, etc. And mirio gave vague answers causing more confusion. It was a mission and I lost my quirk, Why not, things like that.
Things that would normally make Nejire yell. She wonders if that's on purpose.
The questionnaire continues for around half an hour. "Are we done now?" Mirio asked looking at Eri who was sleeping peacefully in his arms. "Fine. But only because of Eri." Nejire cooed at the girl. Mirio chuckled and waved bye to Nejire and Tamaki.
"Let's get you to your bed." He whispered.
