Ningen Fushin no Boukensha-tachi ga Sekai wo Sukuu you desu

The city of Terene in the Holy Kingdom of Dinez is a melting pot of races and professions: adventurers looking to get rich quick, quick-witted merchants, singing and dancing bards, nobles, holy men, beastfolk, and more. The town itself is so labyrinthine that it has been nicknamed the Labyrinth Town.

Nick, a heartbroken Light Warrior who has been kicked out of the Martial Arts adventuring party and deceived by his lover, is a resident of this city.

Fed up with everything, he visits a bar only to find bad food, adventurers living it up, and uninteresting tablemates.

As he drowns his sorrows in lukewarm beer, all of his irritation and discontent burst forth in one declaration:

"Humans can’t be trusted!"

He thought he was only voicing his own frustration, but in reality, the statement came from four voices…

Thus begins the adventure of four people who each carry their own scars!
