Salaryman Tsuyoshi Mukohda is summoned to a magical world along with three others. While they are imbued with powers, Mukohda's new skill seems to be less extraordinary.

On the way to the neighbouring kingdom, Mukohda forms an alliance with a Fenrir, a legendary monster, who agrees to hunt for meat as long as Mukohda cooks it.

After Fel hunts a huge haul of monsters, Mukohda sells some of them to the Adventurer guild, which immediately makes him a wealthy man.

Mukohda discovers he possesses magic and figures out how to use it. Later, Fel starts to teach him and forces him to fight a goblin village.

Mukohda and Fel see a newborn slime upon their arrival at the lake. He later names his new comrade as Sui. Ninrir, the Goddess of Wind, offers to grant Mukohda her blessing to increase his magic in exchange for sweets once a week from Mukohda.

Fel forces Mukohda to enter the dungeon to gain and improve his battle experience. After the drill, Mukohda makes a huge batch of oyakodon for everyone.
