All Might and the Roulette (All Might x Reader)

(Y/N) Shimura: Origins! Part Three

It had been a few weeks since Nana began training Toshinori. His training was going well, at least well enough for someone who still had issues using One for All. But (Y/N) started to realize what Nana saw in him. He had a fire in his eyes, and a strong sense of justice. He'd make a great hero one day. (Y/N) was sure of it.

(Y/N) sat from the sidelines watching intensely at the close combat between the two. The combat was so quick it was hard to keep up at some points. They had been going at it for a few hours now. Toshinori's lips formed into a small smirk as he landed a hard hit on Nana. "I think I'm catching up to you, master." Nana chuckled, wiping some blood off her lip.

"Is that so? Then I guess I'll have to add more of a challenge." She turned her head towards (Y/N). "Kid, you're up!" (Y/N) jumped a bit. She was really going to let her fight him? Hey eyes suddenly shifted to a green color.

"Seriously?" Nana gave her a nod. (Y/N) jumped up pumping her fist in the air. "Alright! Let's go, Yagi! You better not hold anything back!" She made her way towards him, but was stopped by Nana. She gave her a stern.

"Just make sure to keep track of your time limit." (Y/N) gave a nod. That means she needed to make this fight quick.

"I know, Nana. You don't have to worry." She smiled, and continued to make her way towards Toshinori. Nana looked over at her protégé.

"Yagi, I want you to use One for All this time! You need the practice." He jumped a bit. "Y-You aren't serious right? That could seriously hurt her!" (Y/N) rolled her eyes which started fading from green to a red.

"Don't underestimate me, Yagi. Who says you're gonna be the one to win anyways?" She teased. Toshinori smirked, this girl was confident, but that just made him more determine to win.

"Please try not to kill each other." Nana muttered, as the two started to distance themselves from each other. Toshinori couldn't help but feel a bit excited about seeing (Y/N)'s quirk for the first time. He always noticed the change in eye color, but she's never quite told him what it actually is. Only hinting that it had to do with her emotions. "Begin."

Toshinori was the one to make the first move. He swung at her, but to his surprise she ducked. For awhile they went into a pattern of back and forth swinging, landing a punch or a kick on each other every now then, neither of them using their quirks just yet. It was an intense close combat battle, since that was both their specialty. Finally, he swung at her, One for All charged up and ready to make this a short fight. However, her being as quick as she is, she ducked once again. His fist ended up punching a tree, hitting it so hard that it fell over.

"Aw, at least we have plenty of firewood now." (Y/N) gave him a slight grin, now standing behind him. She swung her leg around, just as it was becoming engulfed in flames, kicking him square in the back and sending him into another tree. It also ended up getting knocked down. Damn tree killers. Toshinori couldn't help but feel shocked. He didn't expect that coming from (Y/N). Maybe he shouldn't have underestimated her.

(Y/N) started walking over towards him. He hadn't gotten up yet. "Come on, Yagi. I didn't kick you that hard. Don't play dead with me." When he still didn't move, fear shot through her body. She ran over towards him, kneeling down on the ground. His eyes were closed. "O-Oh no.." The color in her eyes shifted to blue almost immediately. "Y-Yagi?"

Suddenly he grabbed her arm, and flung her over to his opposite side, knocking the wind out of her. Using the strength of One for All just made it hurt ten times more. Just as soon as her eyes where blue, they faded back to red. "You shouldn't let your guard down so easily, Shimura." He said, standing up and brushing himself off. A small smirk covered his face. "All though, I did feel a small sting." Anger welled up inside of (Y/N)'s body.

"That was a dirty trick, Yagi!" She stood up, flames starting to consume her body.

"Hey, there's no dirty tricks when it comes to fighting a real villain! You do whatever you can to win, whatever you can to make sure the people are safe!" He argued. They glared at each other. The flames started to grow larger around her form, neither of them realizing except for Nana.

"But you aren't a villain!" She shouted back. Nana started to march over to them.

"(Y/N)! Calm down! Remember you have a time limit!" She glared over at Nana. "(Y/N), you remember what happened last time you let your anger get the best of you? You don't want that to happen again, right?" The flames started to die down slowly. Nana was right. She needed to calm down. She could start to feel herself on the verge of losing control. Her flames died down completely, eyes returning to normal with a hint of a light blue in them.

"I-I'm sorry, Nana." She felt like she was about to break. She bowed towards Toshinori. "I forfeit. I'm sorry, Yagi." Her voice cracked a bit as she began to walk away, trying to avoid looking at the both of them. "I'm going out for a walk." Nana sighed. Toshinori looked over at his master, confusion written on his face.

"What just happened?" He asked. Nana still looked in her sister's direction as she faded in the distance.

"(Y/N)'s quirk, is an interesting one to say the least. As I'm sure you've noticed her eyes change color depending on the overwhelming emotion she is currently feeling. With each emotion, she has a different quirk. They are mostly related to the elements like: fire, water, and earth, but there are others too. However, when it comes to her negative emotions, like anger..." Nana paused, turning to face her protégé. "She can become a completely different person." Toshinori tilted his head.

"A different person?"

"Yes. It's like she has multiple personalities, her anger being the most dangerous of them all. Because of this, she has to keep to a strict time limit and not let a negative emotion overpower her. Cause if it does, we would lose the (Y/N) we know. Her personality, it would be as if it never existed at all. I almost lost her to it once..." Nana sighed looking back at were (Y/N) left. "Young Yagi, could I ask you a favor?" He looked up at her. "Please accompany her on her walk. I don't want her to be alone right now, and I'd just make it worse if I went." Toshinori nods his head. He didn't need to be told twice. He started running after her.

"Hey, Shimura! Wait up!"
