A decade ago, princess Krystal Novaty “Hime” Nokanatika traveled from another world to escape assassination attempts by an evil force. When she arrives in modern-day Japan, she encounters Haruto Satou. With him she shares a promise: he must forget what he has just witnessed, and the two will become friends. Now heading back to the Nokanatika Kingdom to fulfill her royal duties, Hime bids farewell to Haruto. However, when the young man suddenly remembers his first meeting with Hime, he rushes to the location where she first appeared and crosses the dimensional portal to be reunited with her. His arrival disrupts the marriage ceremony between Krystal and prince Marmarugias Gisaras. The wedding is brutally interrupted by the attack of an abyss monster who threatens the princess' life. Acting impulsively, Hime decides to exchange rings with Haruto, which grants her new husband light powers that permit him to slay the monster. Now dubbed as the Ring King, Haruto must marry four other princesses to acquire new magical powers and have a chance to prevail in his fight against the enemy of the world: the Abyss King.

Kohachi Inugami, a detective who specializes in the occult, arrives at a remote village in the Japanese countryside, tasked by a hostess at a local inn to investigate a string of incidents involving rotting and mutilated livestock corpses that have been appearing for seemingly no reason. While surveying, Inugami notices a peculiar young boy working in the fields. Evaded by his peers and called Dorotabou for his stench, the young farmhand is surprised that anybody would take an interest in him. Inugami, piqued with curiosity, enlists Dorotabou in helping him with the investigation, despite scorned looks from the villagers. Unbeknownst to Dorotabou, this investigation will reveal a strange new world to him—one of the beast-like entities known as Kemono existing in tandem with humans—along with breathing new purpose into his previously empty life.

Yin and Ning are two sisters who have been wandering the land together ever since their village was destroyed by the villainous Taibai Empire. Their childhood friend, Zhao, has been enslaved by the Taibai himself, and uses his brilliance at tinkering and inventing to get by as a slave to the Empire's whims. One day, Yin accidentally discovers a legendary sword, which grants her fantastic abilities in combat, and allows her to summon a mystical, mechanical fox spirit named Yun, who is sworn to fight by her side. Meanwhile, Zhao is making fast friends with a mysterious young girl who just may hold a great amount of power within the Taibai Empire. As Zhao and the Fu sisters find themselves increasingly caught up in the Empire's battle for supremacy over the land, it will take all of the magic and might that the budding resistance armies can muster to turn the tide of war once and for all.
