The protagonist, Akira, awakens on a cliff overlooking a vast ocean and a savanna-like wilderness, disoriented and realizing he is no longer in Japan. He discovers he was transported here after a gas explosion in his cheap business hotel room. His only companions are his carry-on bag and the bed he was sleeping on. After a period of denial and smoking, Akira recalls the events leading to the explosion. He was in a rundown hotel room, frustrated by the "No Smoking" sign, and decided to light a cigarette. Before doing so, he performed his usual ritual of offering a prayer to a crude wooden charm he made in elementary school, a habit he developed for mental stability. The moment he struck his lighter, the world exploded.
He then finds himself in a void, facing his wooden charm, which speaks to him. This "god" reveals that Akira died in the explosion but was saved by its intervention. The god, having gained divinity through Akira's long devotion, explains that it can interfere with the world's rules but is limited by the power of the world's top three deities. To revive Akira, it has found a world with high "materialization interference rate" where he can live without hardship. However, to be resurrected, Akira must offer the god's symbol to the temples of the world's top three deities: Heoris, Telmias, and Aigas. This act will grant him recognition as a god in this new world, allowing his divinity to grow and his interference power to increase. Akira accepts this offer, choosing a new world over oblivion.
Back in the new world, Akira checks his belongings, which include toiletries, clothes, a laptop, stationery, a smartphone, a manga magazine, and medication. He notes the absence of cigarettes, which he had smoked entirely before the explosion. He also realizes his wallet and Japanese currency are likely useless. His immediate goal is to find civilization. He begins walking along the cliffside, hoping to find a fishing village. After a long, arduous trek under the scorching sun, he collapses from dehydration. Just as he despairs, a system interface appears, offering him water for a nominal fee. He discovers he can purchase items and store them in a "container" using his remaining Japanese yen, which are converted into the local currency. He also learns that his "god" has granted him a "Shop" and a "Container" system, and his "divinity" level is currently one.
Akira gradually learns to use this system, purchasing water and food. He discovers that certain items, like his carry-on bag filled with his belongings, can be stored and even form "sets" that appear in the shop. He also learns that his divinity level can be increased by engaging in activities related to his "god of commerce." He attempts to buy a katsudon sandwich, which was previously unavailable, and succeeds after his divinity level increases to two. This allows him to purchase more items and also enables the conversion of local currency into Japanese yen.
While walking, Akira encounters two suspicious men who attempt to rob him. Just as he is about to be stripped naked, a dwarf named Hag, a traveling blacksmith, intervenes. Hag, who possesses an "item bag" similar to Akira's container system, easily intimidates the robbers. Akira, grateful for his rescue, explains his situation, albeit with a fabricated story about a shipwreck. Hag, intrigued by Akira's plastic water bottle and the concept of a "container," offers to help him find a town. They agree to travel together, with Akira planning to find the temples and Hag intending to earn money as a blacksmith. Hag reveals that the world has a system of gods and that Akira's situation might be related to a newly born god. He also advises Akira to be discreet about his abilities. They eventually reach a town, guided by a lighthouse, and plan to split up temporarily to pursue their individual goals.
