Reborn As An Overpowered Mage

Hi my name is Nagisa Suzuki and I'm from Tokyo and I work at a café most of the locals go to. And I was walking home from work and I went into the middle of the street all of a sudden I was hit by a truck. And then I heard "look its a boy Akio" said a woman that was blurry I thought "was I reborn in a diffrent world". I looked around at saw a house with a bunch of books and then the woman said "lets name him Akira Takahashi" "that sounds good Alice". when I was 3 years old my mom would take me to the local time it was like we were in the past there weren't any cars there and I found out there is magic in this world so when we got home I tried to use magic but I couldn't so I would practice every day when my parents were asleep. Then when I was 4 trying to use magic it worked I was reading books about magic and imagined a ball of water floating in my hand and it worked. so I imagined a ball of fire and burned the house down while my dad was at work he was a knight and my mom was coming home from shopping and saw the house she ran to it and put the fire out with water magic she got me and said "What happened Akira". " I used fire magic mom" I said " WHAT DO YOU MEAN AKIRA YOU'RE ONLY 4 THE AVERAGE AGE IS 16" she yelled "I didn't know I was just reading the books on magic in the Library we have mom" I said.
