Harry Doesn't Want to Be a Wizard, He Just Wants to Be a Superhero

Harry's Diary:

1991/6/23 I traveled to another world and was adopted by a couple who are very gentle, much better than Aunt Petunia's family!

1991/7/31 I returned to my original world and received a mysterious email. Oh my, it was an invitation to a magic school!

1991/8/8 I saved the world's richest man, Tony Stark!

1991/9/9 I encountered a mysterious person who seemed... very weak?

1991/10/10 I was taken as a disciple by the Supreme Mage. With the magic power within me, I don't need to pay the price like others do!

1991/11/11 I became the greatest wizard of all time!

......

Years later, the Supreme Mage, Chaos Controller, Third Generation Dark Lord, and the strongest wizard in history, Harry Potter, calmly said to the frenzied reporters:

"Although Thanos is weak, he is right about one thing: this world needs a new order!"
