I Don't Care About 僕の vs My for Hero Academia

The official title of My Hero Academia is... exactly the words I just said. Given how heavy the influence of American superhero comics is on the work, it's not that surprising to have a Japanese text with an official title in English. Since it's published in a magazine primarily targeting kids, there's a Japanese translation of the title in the logo, as we can see below.

tl note: Boku no Hero Academia means My (casual male singular pronoun) Hero Academia
