The dragon trinity.

U.A

The night after we opened the letter, All Might got in touch with us. He told us to meet on the beach. We bumped into Izuku on the way there. "(All panting) Hi. All Might!" Izuku screamed. All Might coughed up blood, "Too load, kid!"
"All Mights here?"
"No way! Where?"
Some people on the pier said. All Might shook "Way to blow my cover. Say it was a mistake." Izuku then yelled"I was just kidding! Nothing to see here!"
"Lame."
"I wanted  an autograph."
We all sighed. All Might raised his hand "Congrats on getting in." "We could have done it with out your help!". "Oh speaking of which I didn't tell anyone at UA that I've been training you guys or anything." "Hm?" "Really. I wasn't one of the judges, and I didn't pull any strings for you guys. You earned that spot all on your own."
"Woah thanks for telling me. I'm glad to hear that. Oh ya I was really surprised to hear that you're gonna be a teacher a teacher at UA this year! I was wondering what brought you hear all of the sudden. After all your agency is in Minato, Tokyo. And everyone knows-" "Gettin creepy." 
All might looked at us and said. "And you two, you guys got the first tie for 1st place in the history for the school." Izuku looked at us with wide eyes. "Seriously! Whoa you guys that's awesome." We rubbed our necks "Ya sorry, we weren't trying to get super high points, but at least Bakugou isn't in the top. Wonder how he took that?" He laughed and looked at us "You guys don't have to apologize. You did your best and I did mine. But I do kinda wish you guys where there with me. I took out that e 0 pointer!" Me and Ben looked at each other and said to him. "Ugh we actually took out ours too. We both dive bombed it to the head."
"Ok back to you being a teacher." Ben said. All might coughed and continued. "The school didn't want me telling anyone about the job until they made an official announcement. It seemed like fortuitous timing. An easy way to find some new to inherit One for All." So that's it. If he didn't give it to izuku, he would have given it to a UA student. Some one who already had a quirk. I can't imagine our life he didn't give it izuku. I think it's better that he gave it to him anyway.

"Your power completely wrecked my body. And all I did was jump and throw one punch. I can't control it. What do I do?"
All Might turned around. "You'll l learn to manage it in time. Hoping to master it right away is like asking a baby to run a marathon. You still need to go through the process of learning how to walk."
"Ya...  Wait! You knew I was gonna get hurt that badly?"
"Ya what the heck" I said.
"Well... we were in a time crunch. But it turned out all right. Plus now you know what your dealing with." All Might picked up some empty can. "Right now, your quirk is earthier all or nothing. One day you'll learn how to control your out put. Then you can adjust exactly how much power your using." Izuku gasped" I just need control."

"Right now your overflowing with energy. With training your body'll hold it better." The then transformed and crushed the cans." Then it's yours to command." Izuku gased and I smiled, I didn't realize my phone was vibrating.
"Look it really is All Might!"
"No way! Where'd he come from?"
All Might groaned. "Right, now we run" "Huh? Okay!" We said in unison. We then ran down the beach it felt nice.

The next morning, we got up, showered, shaved(because where 16, in the middle of puberty, and our grandparents came from Germany, so we got that hairy gene) and put on our uniforms, that were measured for us. "Ok mom, where leaving. Love you." We turned to the door. "Oh you can forget these." My dad handed us little wooden containers, about as big as a shot. "Oh thanks dad."

(I don't actually do this, I made this up for the story, cuase I thought it was kinda cool, and funny. Don't judge.)

The things our dad gave us have been handed down since my grandparents moved to the US as kids. They came up with them. Every new year of school they drank them. It's really dark, rich coffee, with a drop of scotch. It's coffee that a family friend from Germany who grows coffee. Really, really good coffee. And the scotch, is from the same guys grandparents.
