It had been a week since Izuku had arrived at the Todoroki household. He seemed to have gotten a little more comfortable around the family, but he would typically sticking closer to Enji when he was home. He wasn't as jumpy as when he first arrived, and somehow Fuyumi had been allowed to hug him, but something about Izuku made Rei worry. In the last couple of days, she noticed Izuku seemed to have less energy than he should and acted more like a zombie. Especially after, he walked into Touya last night and didn't even seem to recognize it.

Rei was in the middle of fixing up a bit of lunch for herself and Izuku, seeing as Enji was at work, and the kids were at school. After finishing their lunch, Rei found Izuku on the couch watching TV, but when Rei called Izuku over, he didn't even respond. Walking over, she saw that Izuku had completely spaced out, she crouched in front of him and tried to get his attention. After that failed, though, she carefully grabbed Izuku's shoulder and gave him a light shake, this got Izuku's attention.

"R-rei…what's going on?" Izuku mumbled

"Izuku, sweetie, are you doing ok?" Rei asked, her worry clearly on display for the six-year-old in front of her.

"I-I'm ok" Izuku replied

"Izuku, please don't lie to me. A second ago, you weren't responding to me at all, and you look a mess." True to her words, Izuku looked almost like a zombie, his skin tone was paler than usual, and Rei noticed bags had started forming under his eyes. "Please, I want to help but I can't if you don't tell me what's wrong" Rei pleaded

"Rei…I'm ok."

Seeing Izuku was refusing to cooperate, Rei decided to at least get Izuku his lunch, but as she moved away, her hand brushed against Izuku's leg. Immediately she noticed how warm the limb was. Her maternal instincts kicking in almost instantly, she dashed to the kitchen and grabbed the first aid kit. Returning to the living room, she pulled about the thermometer and checked Izuku's temperature, after waiting the necessary amount of time, she looked at the reading and was left confused. Izuku's temperature was normal.

'If he's not sick, then why are his legs burning up? It can't be from exercising, he's still a child, what could it….' And like a bolt of lightning went off in Rei's head. She remembered what Enji had told her about Izuku's quirk and how it solely affected his lower body, unlike other fire quirks where it either effect their hands or their whole body.

"Izuku…is your quirk, making it difficult for you to sleep or something?" Rei asked, Izuku visibly flinched at her question, that was enough of a response for Rei to know something was wrong. "Izuku, sweetie, no one is going to get mad at you if your quirk is acting up or making you uncomfortable. So please tell me what's wrong," Rei pleaded for a second time.

When Izuku looked to her, though, instead of the look of disgust or indifference, that he was used to, he saw what to him, seemed like genuine concern and worry in Rei's eyes. She was actually concerned for his health and wellbeing.

"My quirk…..it makes my legs really warm, and that makes it difficult to sleep," Izuku mumbled, as he averted his gaze from Rei.

"Wait, if that's the case, why are you only now showing the lack of sleep?"

"In the hospital, I kept the window open to keep me cool, but I didn't want to make Shoto uncomfortable in his room, so I tried to work through it."

"Oh, Izuku…That's sweet that you care that much, but what you did was very dangerous. If you don't get enough sleep, you'll end up hurting yourself in a lot of ways, and we don't want that, do we?" Izuku shook his head at Rei. "Good, besides I'm sure Shoto wouldn't have a problem with the room being a little colder for you if it helped you sleep."

"I'm sorry I made you worry, Rei."

"Izuku, it's my job to worry. Now, how about you go for a nap and don't worry, I know how to deal with your quirk" Izuku curious to see what Rei's idea was, watched as she took the space next to him on the couch. She pulled him closer, and suddenly Izuku could feel his legs starting to cool down, looking to said appendages, he saw Rei was using her ice quirk to keep his legs from overheating. Izuku found it rather soothing, it wasn't long till Izuku was curled up next to Rei, fast asleep. But her smile turned into a frown as she watched Izuku sleep soundly.

'I hope Enji makes sure whoever abused Izuku, get what they deserve…. otherwise. I'll deal with them myself.'

Endeavour wasn't enjoying what today had in store, none what so ever. The day after Izuku moved in, Endeavour had started investigating Izuku's school. He wasn't planning on Izuku going back anyway but wanted to make sure anyone who had abused him or ignored his pleas for help, got what they deserved. Currently, Endeavour was watching one of Izuku's teacher's being interrogated by Tsukauchi, a detective All Might had recommended to Endeavour a long time ago. Frankly, he didn't know why All Might had such a high opinion on him, maybe it was his skill, or he had a quirk that helped him. The intercom was on. Endeavour wanted to hear what they thought on the boy; he and his family had grown fond of.

"So how would you describe, Izuku Midoriya?" Tsukauchi's voice coming through the intercom, the teacher groaned at the mention of Izuku name.

"The little monster was always a problem, always starting fights with other students and acting like we were beneath him," the teacher sneered. "I'm glad he's gone, it's easier to teach the students that want to learn."

"So you're saying you never noticed signs that his mother was abusing him?" Tsukauchi asked, keeping a certain level of professionalism with the teacher.

"Never" The teacher replied

The rest of the interviews were the same. The teacher would say Izuku was a little monster that would cause issues with the class, and when asked if they noticed any signs of abuse or bullying in any form, they all said no. It wasn't till Tsukachi was finished with the final interview, that Endeavour realized he had melted the armrest of his seat, in a subconscious show of anger. The teacher's description of Izuku was clearly a lie, he knew he had only known Izuku for over a month but none of what the teachers said, matched the Izuku Endeavour knew.

It was then, Tsukauchi walked into the viewing room, he let out a sign as he adjusted his hat. Endeavour wondered how the man seemed to walk around in a full trench coat, without passing out from heat exhaustion, especially when around him.

"Well, I can tell without a doubt that those teachers were lying through their teeth," Tsukachi stated as he took the free seat next to Endeavour.

"I had my suspicions. Everything they said sounded nothing like the Izuku I know. But how could you tell, you haven't met Izuku?" Endeavour asked curious hoe the detective saw through the teachers' lies.

"Easy, thanks to my quirk, I'm the equivalent to a lie detector. Everything they said, my quirk confirmed to be a clear lie. Besides, my bullshit meter was off the charts on some of those descriptions," Tsukauchi chuckling near the end of his sentence. "Still, Izuku was likely getting bullied at school, and the teachers are covering it up. Pretty sure with what we got from the interviews and the evidence, I can call the teachers back and see which crack under pressure and start telling us the truth."

Endeavour now understood why All Might recommend Tsukauchi so highly. It was clear he was determined to get to the bottom of the cases he was working on.

"I'll call the teachers…... Why is you're chair half-melted Endeavour?" Tsukauchi asked perplexed, Endeavour bowed his head slightly, avoiding eye contact with the detective. Mumbling, he'll replace the chair.

It had taken them all day, but Tsukauchi and Endeavour were able to make one of the teacher's crack. Endeavour chuckled, remembering how quickly the teacher turned pale when Tsukauchi told the man what his quirk did. Soon the rest of the teachers followed their peers, revealing how Izuku was the class's punching bag. How they let the students do whatever they wanted to Izuku and never interfere. Apparently, one student had gone out of his way to rally the class in bullying Izuku, especially when his quirk was found out. Endeavour was late home, thanks to this, but was surprised when Rei didn't greet him at the door.

Curious, Endeavour headed into the living room and found what he could only describe as something genuinely adorable. Rei was sitting on the couch, on her right was Izuku sleeping soundly while cuddling into her side. While on her left side, Shoto was doing the same thing as Izuku, Rei in the middle of this little hug pile, wore a massive grin as she soothed the two sleeping kids.

"Someone's in a good mood," Endeavour said, drawing Rei's attention from the two kids.

"The best mood," She whispered, trying not to wake up the boys.

"So, what started this?" As Endeavour asked this question, Rei lost her smile and changed to a look of concern.

"Izuku…. You know how he's been almost like a zombie lately?" Endeavour nodded "Well…turns out his quirk was making it difficult for him to sleep, it was too warm for him. And he didn't want to make Shoto uncomfortable, so he tried to work through it….and you saw the results."

"So you made him take a nap, why am I not surprised" Endeavour chuckling, not surprised Rei had done this. Hell, he remembered plenty of times she did that with him, when he was, according to her, working too hard. Granted, she usually cheated throughout the years, normally by using one of the kids to get at his heartstrings.

"So that explains Izuku. But how does Shoto fit into this?"

"That…. actually is the funny one," Rei giggled "He got a little jealous of Izuku getting all my hugs, so after dinner. He asked to join in…. I couldn't say no to him"

'Yeap, that defiantly sounds like Shoto.'

"So I take it your stuck?"

"I could move…... But they're too cute like this" Rei was indeed caught between a rock and a hard place now, or more accurately. She was stuck between two adorable hero lovers. Seeing Rei wouldn't be able to make it to bed, Endeavour grabbed a spare blanket from his room and draped it over the Rei and the boys. Making sure they were comfortable before heading to his own bed, but not before kissing Rei on the forehead.

A/N: To be frank, I was surprised how quickly i got this chapter done, it was mainly thanks to a friend the other day, who got me excited to write. Overall I loved writing best mum Rei, she's so sweet, I can't wait to do more with her.

Anyway I hope you all have a great day, see ya!
