Our unnamed protagonist is an ordinary high school boy who loves Magic Walker - a super-popular card game. In particular, he loves the Elf Deck: a selection of cards that, while seemingly weak, can be incredibly powerful when played right. One day, while on his way to get a new elf card, he gets bullied by his peers. One thing leads to another, and soon he wakes up in another world... in the body of the elf character he was hoping to get his hands on. And wouldn’t you know it, he can summon elf cards from his old world too.
The world he woke up in is long dead, dusted in ashen powder, and yet Keisuke still sees splashes of color as he travels through it. For the longest time, he’s wandered alone across the deserted landscape, clinging to the hope that something—or someone—might be out there in the emptiness. When he finally stumbles across that someone, even more threads of color start to seep into the ashen world around them. This time, when Keisuke sets off down the road, someone sits beside him in the passenger seat. The first acquaintance he’s ever made here, his first companion in this barren world. They’re both traveling in search of something, and after searching alone for so long, maybe they’ll have better luck working together? Their only lead is a witch who can answer any question—for a price. What will the two ask her, and what will she be able to tell them? More importantly, what will it cost them, and will they be willing to pay the price?
