My name is Izumi Midoriya, and this is the tale of how I not only became the greatest hero but the greatest Master and Devil as well. It all started when I was four and I woke up with my right hand slightly aching.

"Hmm, must've slept on it," I said, stretching. I got dressed and headed out to meet up with Kacchan to go to the park to see if we could figure my quirk out.

"What took you so long?" Bakugou asked, annoyed.

"S-sorry, I slept on my arm," I said, scratching the back of my head.

"Ugh, you are going to be a terrible hero with stuff like that," he sighed. "Let's go," he said, walking across the street.

"Wait up!" I yelled, running next to him.

"So, what should we try today?" he asked.

"I don't know," I said as I turned to see a semi-truck slamming on the breaks and honking almost on us. A quick flash of red light came off my right hand and I felt someone pick me up.

"Huh, you're going to be a difficult master, huh?" a female voice asked as I was set down next to Bakugou.

"M-master? Who are you?" I asked.

"I'm your servant, Nero Claudius of the Saber Class," the woman said. I turned to look at her. She had beautiful long blonde hair, wore a red and white dress, had a smooth beautiful face, and bright lime green eyes.

"W-wait, are you part of my quirk?" I asked.

"Hmm, I have no clue what a quirk is, but I am under your command," she said. "At least, for now," she added, smirking.

"Um, what the hell?" Bakugou asked.

A few minutes later my mom was driving me and Nero to the quirk doctor to see what all my quirk was. We were led to a room and after a bunch of tests were led to a room with my mother.

"Well Mrs. Midoriya, your daughter's quirk is interesting to say the least," the portly doctor said. "It would seem she can Summon what Nero here is calling Servants of different Classes. She said that they were Saber, Archer, Rider, Berserker, Lancer, Caster, and Assassin," he explained. "Most of them are historical figures and some are fictional figures from what she knows of them which she admitted was limited. We also noticed that her being here is causing a small amount of an energy in your daughter to run out, but if it regenerates when she sleeps or doesn't have a Servant with her she should be fine for a while. Also, there seems to be this black mark, almost like a tattoo, on her right hand. We believe this is where the power goes for her to know how many Servants she has summoned at a time."

"Woah, this is a lot, especially for a quirk. Are we sure about this?" my mother asked.

"As of right now, yes."

"Alright, thank you. Let's go home, Izumi, Nero," she said, looking at us.

On the ride home, mom and Nero talked in the front of the car while I was in the back and couldn't hear them. I could tell by a couple of outbursts that something surprised them but couldn't tell what. When we got home mom said she would draw a bath for me.

"Mom, can Nero join? It would be a good way for us to get to know each other and she can be like my older sister or something," I said.

"Oh, well would you be alright with that Nero?" my mom asked.

"I guess my master is worthy to bathe with me," Nero said, smirking at me.

A few minutes later the two of us were in the bath together with our feet barely touching.

"S-so, what were you before you were summoned?" I asked, trying to not look at her.

"Well, I was the Emperor of Rome for some time before I was overthrown because I thought a person who was making a lot of noise wasn't worth sending men to deal with. I loved my people, and they betrayed me," she sighed. "So, what is your plan as my master?"

"Well, I was wondering if you would help me be a hero," I said.

"Ah, a hero. I suppose it would be alright to help you, but first we need to come to some agreements," she said. "As my master I will give you and your mother permission to refer to me as an equal and I will do the same."

"Alright, well how about you help me be a hero and I'll help you get adjusted to this society? It's really different from ancient Roman times," I said.

"Deal, oh, I should also let you know that I am of the Saber Class right now. I'll also help you learn to summon other Servants as well as change the class of them, like mine. If you want I can be summoned as a Caster or a couple other ones, but you can learn about that after you have more servants and are older," she explained.

"Alright, um, do all Servants need an agreement?" I asked.

"Well, not all but I am one of the best so I thought it would be a good idea," Nero said.

"Oh, ok then."

For the next year Nero taught me how to use her powers and how to be able to summon new Servants. After some testing we learned that until I had one of each Class I couldn't summon her as a Caster or her other forms. We figured I wouldn't have enough energy to safely summon one until I was a year older. My mom made me agree that I could only summon a new Servant once a year. During this time Bakugou started calling me Deku meaning useless because he said my quirk doesn't let me do anything and would be useless for hero work. He started bullying me too but I wouldn't tell mom or Nero. Dad moved to America for his job to make more money. Then, the day for me to summon my next Servant came.

"Alright, let's see who you summon," Nero said, standing back. She wore a red summer dress instead of her armor.

I took a deep breath and put my right arm out. "By the will of the almighty power that resides in me. By the righteousness of Heaven and the corruptness of Hell I call to thee. Servant who will stand by me, come to my call and power from within!" I said, opening my eyes as a red magic circle appeared and a person started to form in the middle.

"Hey, I'm guessing you are my Master," a woman with green hair, animal ears on her head and a tail swishing behind her said. She wore mostly green clothes with a bow on her back. "I am Atalanta of the Archer Class."

"Ah, the Archer of Red," Nero said.

"Red Saber, pleasure to see you again," Atalanta greeted.

"Umm, you know each other?" I asked.

"Indeed, we met in the strange space where we are before being summoned. I am your Servant, may I have your name?" she asked, looking at me.

"Izumi Midoriya," I said.

"Well, you can think of me as your loyal protector," she said, giving a slight bow.

"A-alright," I said.

"What the hell are you doing Deku?" Bakugou asked, walking up to us as we were in the park. I had permission as we needed an open space.

"I-I just summoned a new Servant, Kacchan meet Atalanta. She's an Archer Class," I explained.

"Huh? You have another one of those weirdos you can summon?" he asked.

"Well, I can only summon a new one once a year for my safety but after sometime we think it might change," I explained.

"Tch, don't think this makes you better than me. At least I don't need others to do stuff for me," he snarked walking away.

Mom decided that we needed a bigger house and a bigger bathtub if Atalanta was going to be with both Nero and I in it. Atalanta decided to help get money by getting a job at an animal shelter. Nero helped mom with the house work so she could work some more hours(even though she thought that it was beneath her) and even learned she was as good as my mom at cooking. After a while my mom managed to buy a house with a plot of woods and a natural hot spring. The house was two stories with five bedrooms. I changed schools and got along with everyone in my class. A year later I summoned my next Servant.

I said the incantation and watched as the red circle appeared and a girl with blonde hair held up in a ponytail, green eyes, a red skirt, red sleeves, and a red chest covering.

"Hey, it's Mordred," Nero said, giddy.

"Eh? I'm a Rider!?" the new Servant exclaimed in surprise.

AN-

So this is another idea that's been in my head since I started and now I'm fully solo writing, I thought this would be a second good one to write. This is combining MHA, Fate, and High School DxD. I'm excited to see how people like this. Follow, favorite, comment, and kudos! Link Out!
