The Magical Kingdom of Klyrode summons hundreds of heroes from other worlds every year to fight in their war against the Dark One and his army of powerful demons. Banaza is one of those heroes, summoned from the Royal Capital Paluma, but something's not right—Banaza is only an average merchant. He has no magic, no fighting ability, and his stats are abysmal. Worse, a mishap leaves him unable to return home! Rejected as a hero and stranded in another world, abandoned to the far reaches of the kingdom by a cruel king who just wants him gone, Banaza's fate looks pretty bleak. But what will happen once the failed hero candidate finds himself with super cheat powers once he hits level two?

Hidden in plain sight, spirits known as youkai inhabit the world. While most are benign, a certain subset threatens the tenuous peace between youkai and humanity. Ever since she agreed to become their "God of Wisdom," Kotoko Iwanaga has served as a mediator between the two realms, resolving any supernatural problems that come her way. At a local hospital, Kotoko approaches Kurou Sakuragawa, a university student whose long-term relationship ended with an unfortunate breakup. Kotoko harbors feelings for him and suspects that something supernatural lurks within his harmless appearance, so she asks Kurou for his assistance in helping out youkai. Two years later, news of an idol who was accidentally crushed to death by steel beams flooded the press. However, months later, sightings begin to tell of a faceless woman who wields a steel beam. As is the case for any supernatural problem, Kotoko and her partner set out to stop this spirit from wreaking havoc—but this case may prove to be far more sinister and personal than they could have ever thought.

Takuma Sakamoto is a hikikomori gamer who is mysteriously transported to the virtual world of his favourite MMORPG, Cross Reverie, with the appearance of his own character in the game, the Demon Lord Diablo. The two young girls who summoned him, the pantherian Rem and the elf Shera, attempt to use a spell to make Takuma their servant, but due to his magic ring with the ability "Magic Reflection", the spell rebounds, and both end up with magic collars stuck on their necks, thus becoming his servants instead. With a serious case of social anxiety, Takuma decides to act like his character while interacting with others, and makes use of his high stats and vast knowledge of Cross Reverie's lore to survive in his new environment, traveling along with Rem and Shera to look for a way to remove their slave collars, while helping them with their own personal issues that led them to summon him in the first place.
