Sekai Saikyou no Doryokuka - Sainou ga (Doryoku) Datta no de Kouritsu Yoku Kikakugai no Doryoku o Shitemiru

MC lives in a world where everything is determined by inherited talents bestowed by "God", the problem is that he's given the talent of "Hard-worker", meaning that if he puts effort he can learn pretty much anything. This is a tricky situation because while he has "no limits" he starts from the very bottom, which is not the reality faced by his contemporaries.

Due to it, he's mocked by his peers but he's not too boomed about it and swears to become the strongest in the world due to a promise with his childhood friend/crush, so he embarks on a journey with the blessings of his parents to do so while she goes to the famous "hero academy".

It's not the most original story out there, but it's competent enough, and the drawings are very cute. All around it's a pretty decent read if you're in the mood for a classic shounen adventure.
