I was reincarnated as the strongest mage in my country

 I was lonely stupid boy with no sense of life my parents died long ago so am on the streets rummaging through trash to get food . then I was forced into the army. i wondered why they needed me. they pushed my body to the limit with the rigorous training exercises . then we were dispatched to go to the war the war lasted long but soon it was over . I finally managed to get a decent income from the money the soldiers were given . I had a good home, a meal everyday It was the best until one day while I was walking . Monsters appeared out of nowhere the crushed everything even my home I worked so hard on all of it was gone in an instant . Then there was this man who brought hellfire and meteors . It crushed people then when I as running to a church to save myself . The church was hit by the meteor . I was heartbroken looking at everything this village was destroyed then when I was running . Meteors hit me . I felt weak they had burned me and the final meteor hit me . I was crying since I knew i have died then I open my eyes then a bright light illuminated the area was glassy then I heard a thunderous voice I look up and see twelve gigantic people sitting down . They told not to worry but I was worrying then they said they want to grant me a new life . Since my old one was so bad .I agreed then they told me they will be watching me then in a flash I heard people say "leon leon takatou"
