Step inside if you dare, but be warned—this is no ordinary shop. Those who enter never leave the same… if they leave at all. A sinister force lurks within, fueled by a dark past and a thirst for revenge. The price? Twelve lives for twelve sins. As officials race to put an end to the bloodshed, the shop’s deadly grip tightens, claiming innocent victims one by one. Will anyone uncover the truth before it's too late? If you crave spine-tingling horror, heart-pounding thrills, and a mystery that refuses to stay buried, this book will haunt you long after the last page.

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos). Everybody wanted out, but there was no way to leave the Void…

Takumi Hirooka(20) works at a black company. He stopped at a convenience store before returning home, and then gave his beloved dog Leo a treat before eating his own dinner that he bought at the store.

After eating, Takumi stood up in order to take a bath, but due to exhaustion from overworking, he fell to the floor and lost consciousness.

When Takumi opened his eyes again, he was in an unfamiliar forest. But what he thought was a large wolf sitting next to him, was actually his dog Leo…

Leo was now big enough to carry people on her back, and could defeat monsters that appeared in the forest in an instant.

A woman they meet in the forest, Claire, tells them that Leo is the most powerful of monsters, a Silver Fenrir.

Takumi couldn’t help but think that this world was all a dream. But after speaking with Claire and witnessing Leo’s strength, he finally realizes that this was another world that he had come to.

They are invited to Claire’s great mansion, and Takumi eventually lives there.

The young man Takumi and the dog Leo who were somehow transferred to this world.

As the powerful Silver Fenrir, Leo will protect Takumi.

While Takumi discovers that he has a gift, it is an ability called Weed Cultivation.

…Could such an ability be useful?

Takumi was tired from so much work, but he uses his ability to live with Leo and Lady Claire. This is his story.
