Clearing an Isekai with the Zero-Believers Goddess

Takatsuki Makoto stands apart from his classmates in 1-A—the measly weakest among the otherworlders. While the Heroes and Sages flaunt their cheat abilities, he's stuck as a Mage Apprentice with a mere 10-year lifespan. The Great Demon Lord looms on the horizon, ready to awaken. The odds are stacked impossibly against him in this broken Isekai. Just when despair threatens to consume him, a breathtaking Goddess with zero believers extends an unexpected offer: become her faithful devotee. But there's a catch—she's trapped somewhere distant, awaiting rescue. Now Takatsuki must navigate an unforgiving world filled with nothing but hardship to save the only one who believed in him. A forgotten mage's journey to conquer an Isekai designed to crush him.
