Here is a short story developed from that premise: Stranded in Another World
The dolphin blinks. "That is not a valid selection."
On day three, starving, he finds a cave. Inside: a rusty sword embedded in a stone and a flickering holographic screen that reads: 「Survival Mode Activated」 "Due to a dimensional error, your isekai package is delayed. Please craft a raft to reach the mainland. Estimated arrival: 300 days." Kaito laughs hysterically. Then he pulls the sword free. No magic glow—just a good, sharp blade. He learns to spear fish, make fire by friction, and weave a shelter. Every night, the screen updates: "Day 4. Calories: 1200. Sanity: Falling." -Doujindesu.TV--Isekai-ni-Ittara-Mujintou-de-Ka...
Kaito looks at Yuna. Yuna looks at the vending machine. It has one button: "Start Over."
Kaito Tanaka, a burned-out office worker, wakes up on a golden beach under two suns. He's been isekai'd—no truck, no goddess, no cheat skill menu. Just a torn shirt, a dead phone, and a vast, empty island. The only clue is a half-buried sign: "Welcome to Another World. Survive." Here is a short story developed from that

Kaito's first day is a comedy of errors. He tries to "open his status screen" by swiping the air. Nothing. He shouts, "Skill: Fireball!" A seagull poops on his shoulder. He realizes: this isn't a game. It's a desert island . Please craft a raft to reach the mainland
"Your isekai package has arrived. Choose one: 1) Return home. 2) A boat to the mainland. 3) A single cheat skill."
