Katsuki Bakugou x Marinette Kirishima

Unveiling Secrets

Aizawa's POV:

"So apparently, Marinette is not the Kirishimas' real daughter. They adopted her, likely in hopes of getting an amazing quirk. It doesn't seem like she has one, though," Principal Nezu explained, his tone calm yet concerned.

"Hmm... and then the abuse starts afterward," I muttered, piecing together the grim puzzle.

"And from the heroes keeping an eye on her, I've learned that Bakugou is often with her."

"Bakugou!? As in our student Bakugou?" I was shocked. What connection did Bakugou have with Marinette?

"Yes, it's odd. Why doesn't Kirishima do anything about it? Or does he even know?" Principal Nezu's eyes narrowed in thought.

"Weird..." I sighed, feeling a mix of frustration and determination. "I need to question those two boys."

Bakugou's POV:

"C'mon," I whispered, pulling Marinette through the window and gently placing her on the ground. She had called me earlier, saying her parents had guests over and they were getting drunk. I couldn't let her stay in that environment, so I decided to sneak her out.

"Let's go," I said, taking her hand. She giggled, trying to keep up with my pace. It was late, and I made sure she wore a sweater to keep warm.

We walked around the neighbourhood, talking and laughing. "And then I went POW, and the damn Deku went flying out of the circle!" I exclaimed, reliving the moment. She giggled her laughter a sweet melody in the night.

"What, you think it's funny?" I grabbed her, playfully tickling her sides. She shrieked and laughed, her joy infectious.

"That's what I thought," I chuckled, pulling her close. Her laughter quieted down, and she snuggled into my chest, her warmth seeping into me.

"You want ice cream?" I asked, spotting an ice cream parlour still open.

"Mhm," she hummed, pulling me towards it, making me chuckle at her enthusiasm.

We reached the parlour and ordered our ice cream cones. She got strawberry, and I chose chocolate. We walked out, licking our cones and enjoying the cool night air.

"Hm?" She gestured towards her ice cream, offering me a taste. I smirked, grabbing her hand that held the cone. I brought her closer and licked the ice cream right next to her face. She blushed red, her hand trembling slightly.

I used my thumb to clean a bit of ice cream from her mouth and then licked my thumb, making her blush even more. "You good, love?" I whispered huskily.

"Eep!" She squeaked and ran off, her face a deep shade of crimson. I chuckled, following her, my heart light and full of affection for this girl who had somehow become so important to me.

The night was quiet, the stars shining brightly above as we walked back to her house. I could feel the tension in her grip, the fear of returning to the place she called home.

"Hey," I stopped her, looking into her bluebell eyes. "I'll always be here for you, Blueberry. No matter what." She smiled softly, her eyes shining with gratitude.

We reached her house, and I pulled her into a tight hug. "Stay safe, okay? And call me if you need anything." She nodded, hugging me back just as tightly.

As she slipped back inside, I couldn't help but feel a surge of protectiveness. Marinette was strong, but she didn't have to face everything alone. Not as long as I was around.

Once I got back to Heights Alliance, I was stopped by Mr. Aizawa.

"Uh—"

"We need to talk," he said, his face wearing its usual sleepy expression but his eyes holding a serious glint.

"Sure," I shrugged, following him to his office. Inside, I found Kirishima already there. We hadn't spoken in a while.

I sat in the chair beside Kirishima, staring at Mr. Aizawa.

"This meeting is about Marinette Kirishima," he began, and both of us snapped our eyes to him.

"What does my sister have anything to do with this?" Kirishima asked, his voice tinged with confusion and concern.

"Funny thing is, we never knew you had a sister. Another funny thing is that while I was on patrol a few days ago, I found your sister passed out in the middle of the street. Another funny thing is that her whole body is littered with bruises, and she also had a few broken bones. Know anything about this? Both of you?" His glare was set, piercing through us.

"I... I know she gets mistreated because she has no quirk, but it shouldn't be that bad," Kirishima said sadly, his eyes cast downward.

"Well, it is that bad. She was malnourished, beaten badly, bruised everywhere. You could tell how tense she got when I told her, her parents were called. She wanted to run away."

"......." Kirishima was silent, his face a mix of anger and guilt.

"And Bakugou, what are you doing with this girl? Reports say you're with her sometimes."

"What? Why are you with my sister?!" Kirishima snapped, turning to me with a glare.

"Cool your tits," I rolled my eyes. "I met her when I visited with Kirishima once. I instantly knew something was wrong. I noticed how she flinches at every loud noise, how tense she is around her parents, and how they don't give her any attention. They yell at her and mistreat her for everything. She cooks and cleans all day. I... I know a secret of hers, but I made a promise not to tell anyone." I muttered the last part, feeling a weight settle in my chest.

"Hmm... well, I can't say much right now, but we're thinking she's getting abused. But I can't do anything until I get real proof. I just need you two to keep an eye on her. Just to keep her safe."

"Mhm... I also gave her my old phone so she can call if anything crazy happens. I added your number as well. So if an unknown number calls, please pick it up," I explained.

"Of course. Go to bed, you two. Thank you." Mr. Aizawa dismissed us, and we both stood up and walked out.

As we made our way to the elevator, Kirishima broke the silence. "So you were right..."

"Hm?" I hummed, pressing the button for the elevator.

"I... I am a bad brother. I was so oblivious and wanted to ignore the fact that my parents were terrible people. My sister... she couldn't even tell me."

"Yeah, well... you know now. And we'll get her out of that horrid place," I promised, more to myself than to him, as we entered the elevator.

The ride down was quiet, both of us lost in our thoughts. The weight of the revelation hung heavy in the air, and I could feel Kirishima's turmoil.

As we stepped out into the hallway, I turned to him. "Look, shitty hair, we can't change the past, but we can do something now. We're gonna make sure she's safe. Together."

He nodded, his eyes resolute. "Yeah. Together."

We parted ways, each heading to our rooms, burdened by the knowledge of Marinette's suffering but united in our resolve to protect her. As I lay in bed, I couldn't help but think of her, hoping she was safe, knowing that from now on, I had to be even more vigilant.

This wasn't just about being a hero; it was about being a friend, a protector, and for Kirishima, a brother.
