Clearing an Isekai with the Zero-Believers Goddess

Story:

"Your characteristics are lower than that of the average person." Weaker several times than the others in Class 1-A, Makoto Takatsuki. Classmates with such cheating skills as "Heroes" and "Wise Men" have already left, leaving me alone. Is my life expectancy only 10 years? Will the Great Demon Lord be reborn soon? Am I a sorcerer's apprentice? Isn't the balance too bad here? This is a fucking trash game. "Do you want to be my follower?" the Goddess asked me. Ahh, damn it is bad…. I don't think I can get through this. A goddess without followers, incredibly beautiful, and she told me that she was imprisoned somewhere and waiting to be saved. My first and most difficult mission is to save the goddess. This is the story of the weakest magician who, in a parallel world, meets only with misfortune.
