Shinja Zero no Megami-sama to Hajimeru Isekai Kouryaku

Makoto Takatsuki dies alongside his classmates and awakens in another world, but the fortune that grants others extraordinary abilities leaves him with poor stats and skills that seem almost useless in battle. Rather than give up, he chooses to study magic and rely on the persistence of a gamer accustomed to searching for a solution when the odds are terrible.

Then Noah appears before him, a minor goddess with no worshippers, and asks Makoto to become her first believer. The weakest boy in his group ties his fate to a goddess with neither followers nor influence. Through training, experimentation, and careful use of every advantage his abilities provide, the two begin challenging a world whose rules never expected either of them to reach the top.
