I've been wanting to do this for almost a year now, and I've finally gotten the inspiration. For now, I'll just leave this here and hopefully, continue later, when inspiration strikes again. Enjoy :D

(Izuki at age 21)

It has been an awful day so far. Eri was being her angsty and almost-always angry teenager self. Don't get me wrong, I still love her but being a young adoptive-mother at age twenty-one was being more difficult than I thought it would be. And worst of all? She was only thirteen! I would have to keep up with her upcoming moods for at least another four years! She was such a cute, understanding, unstressful, shy kid when we first met, and now? She's gotten way too comfortable; sometimes she forgets I'm her mother.

"Eri, please, we need to talk" I was waiting for her to open her door so we could talk about the latest drama in her life "I can't help you if you don't let me in"

"I don't want to talk about it!" she yelled. Yep, that's my new monster-kid. I sighed, I was too young for this.

"C'mon Eri, I don't know what I did wrong this time" I said trying to understand her anger "I've made your favorite, katsudon!" I tried to bribe her "I even asked mama to help make it just the way you like it"

I heard her coming to the door, did I get through to her? But then, I heard a chair being pulled and I knew what she was going to do. I groaned in frustration, she did know I was the strongest woman in Japan, right? Sometimes even she forgets who her mother is. I sighed, what was so wrong that she didn't feel comfortable with me knowing?

"Please baby, I want to help" I was extending an olive branch right now. What else could I do?

"Just leave me alone" she pleaded.

I knocked my head on the door and gave up. I wasn't going to win this anytime soon. I decided to leave it for now, and come later with more determination. I was tired, and I only wanted to do something nice for her. I was being called out more and more ever since I became the number one hero in Japan and I kept missing our family dinners. I knew she was missing our quality time together and it made me feel awful. I heard my phone ringing in the kitchen so I went there to fetch it.

"Hello?" I didn't even look at the caller.

"Hey Zu-chan" Ochako called me "I was just helping out the police trying to catch a villain nearby and I remembered I haven't seen your new place, so, I'm downstairs waiting for you to welcome me in"

"I don't think it's a good time Ochako" I sighed "Eri isn't really in the mood to be welcoming anyone" I said "As soon as she came in, she threw her backpack on the floor and locked herself up in her room, she didn't even say hello"

"Maybe I can help, just let me in" she said.

"Okay, just push the door after the buzz" I hung up.

I opened the door once I peeked through the peephole. I led her to the kitchen and poured us both a warm cup of tea. I took a sip before pouring out my worries.

"I think it's my fault Ochako" I said "I haven't been here for dinner for almost two weeks now" I sighed "She needed me and I wasn't there"

"How do you know she needed you?" she asked.

"It's obvious, why else would she be this angry at me?" I wanted to pull my hair out, I neglected my child and I was paying for it "I hope she isn't being bullied for her quirk"

After all these years being trained by Aizawa-sensei and myself, Eri has gotten better at using her quirk; but sometimes the stress brings out the worst of her. At first, I was being called to the principal's office at least twice a week; but it's been one year since it last happened. Kids are brutal when they're young but they become worse once they hit that age. The same age Eri was right now.

"Did you notice anything else when she came home?" I gave her the look "I know you just explained me what happened, but maybe you forgot some other details?"

"Well, she's been more moody than usual" I said "I mean, teenagers are moody but I swear, it's been three weeks of constant mood changes and just yesterday she was almost crying because of stomach aches, she's never done that"

"I think I know what's happening to her"

"You do?" I was skeptic. Don't get me wrong, Ochako has been a big familial figure in Eri's life; but no one knows my child better than I.

"Just let me try, ok?"

I nodded my head in acceptance and let her work her magic. At least I wouldn't be the one receiving Eri's cold shoulder. After a few minutes, I heard Eri's door being closed and both Ochako and her came into the kitchen. Eri's face was red and I almost could see my shy Eri coming out again; but she took a deep breath and stared at me in the eyes.

"Mama, can I go with you to the farmacy?" she asked.

"Are you sick?" I asked.

"Moh, Zu-chan, can't you tell already?" Ochako was pouting and staring me down in disapproval.

"What is it?"

"Mama, I'm having my period"

I felt so stupid, I knew my face was a big question mark right now. Ochako almost couldn't keep it together. Of course Eri was having her period! It was only a matter of time before she began her period, her birthday was almost two months ago! I groaned in frustration; how did I not notice her cramps? It was obvious!

"I'm sorry I didn't notice sooner baby, we can go right now" I said "but first, go check the bottom drawer in my bathroom, there are still some pads there"

"Thanks Mama" her face was still red.

"Thanks Ochako" I smiled once Eri left the room.

"I figured she would have your symptoms once she became of age, but I was wrong" she giggled.

"We're not blood related, you know?"

"Yeah, but everything about you is amazing, so I guess I naturally thought she would take after you after a while" she said.

"You're my hero Ochako, you saved me!"

"Even the greatest hero needs a hero sometimes" she said. "That reminds me, I skipped 'the Birds and the Bees' talk, I figured you would want to tell her" she giggled.

"Thanks anyways Ochako" I sighed, maybe she wasn't the full hero I needed right now.
