Synopsis
Setting
Revenant Kingdom is set hundreds of years after the events of Ni no Kuni: Wrath of the White Witch. The game begins in the kingdom of Ding Dong Dell, which features the cat-like Grimalkin and mouse-like Mousekin races which have a history of animosity. The kingdom is ruled by the House of Tildrum, with its current heir, Evan, preparing himself to assume the throne after his father's untimely death.
Aside from Ding Dong Dell, the world is divided among three other major realms: Goldpaw, focused on gambling and tourism, ruled by the Dogfolk; Hydropolis, a secluded marine nation of merfolk and humans; and Broadleaf, an industrious, highly advanced nation formed by a corporation that grew large enough to establish its independence. Each country's ruler has a bond with a powerful being known as a Kingmaker. This bond is known as a Kingsbond, and it not only acts as a proof of authority, but also to protect the country and its population from harm. The bond between a ruler and its Kingmaker can only be broken when the ruler dies, or is forcefully stolen, which is only possible when the support of their subjects falter.
The two main protagonists are Evan Pettiwhisker Tildrum, a child and rightful heir of Ding Dong Dell, and Roland Crane, a president from an unnamed nation of Earth who is transmigrated to the world of Ni no Kuni in a younger form of himself, and becomes Evan's friend and loyal companion. The party also includes Tani, a girl of Evan's age; her father Batu, from a tribe of sky pirates; Leander, a young man who is the advisor for Queen Nerea of the island kingdom of Hydropolis; and Bracken Meadows, a young woman who is the top engineer and one of the founders of the industrious country of Broadleaf.
Plot
The game begins with Roland witnessing a missile exploding over a city. In the aftermath, he vanishes and reappears in front of Evan in Ding Dong Dell, with his youth suddenly regained, just as Mausinger, the advisor to Evan's late father, stages a coup. As they escape, they learn that Mausinger poisoned the previous king and intends to have Evan killed to assume control of the kingdom. Assisted by Evan's governess Aranella, who sacrifices herself for their safety, Evan and Roland escape safely from Ding Dong Dell, with Evan promising to her that he will establish a new kingdom in which everyone can be happy and free. Since then, he is occasionally approached in his dreams by a mysterious boy around his age, who becomes his confidant.
Given this, Evan and Roland travel to Cloudcoil Canyon to reach the Kings' Cradle to seek out a Kingmaker for themselves. There, they are joined by a group of sky-pirates, their boss Batu, and his daughter Tani who help them reach the shrine in which Evan undergoes a trial to make a bond with a new Kingmaker. Upon success, Evan is joined by the tiny Lofty, his new Kingmaker. After settling in an unclaimed plain area, Roland instructs Evan to make contact with a neighboring kingdom: Goldpaw, where they learn that Goldpaw's ruler, Master Pugnacius, is making use of rigged gambling to exploit the population. Once Pugnacius is exposed by the party, his Kingsbond is taken by a mysterious man called Doloran. The party later learns that Doloran was once a king from a long lost Kingdom that disappeared in a single day. Despite his errors, Pugnacius retains the support of his people, as he was just being manipulated by Doloran to do his bidding.
Back to their settlement, the party, along with the pirates and immigrants from other nations, establish the nation of Evermore. To plan their next step, Evan and the others seek for knowledge at Goldpaw's library where they learn of Ferdinand, an ancient king who once united the kingdoms of the whole world through a "Declaration of Interdependance", which inspires Evan to do the same. After convincing Pugnacius to sign the declaration, Evan and the others set to Hydropolis, where they fail to prevent Doloran from stealing Queen Nerea's Kingsbond but convince her to sign the declaration. Nerea's loyal advisor and true love, Leander, agrees to join the party to stop Doloran's schemes. A similar situation occurs in Broadleaf, where Doloran steals the Kingsbond from President Zip Vector, who also agrees to sign the declaration afterwards, and the party is joined by Bracken.
After returning to Evermore, Roland leaves temporarily and sets to Ding Dong Dell, where he feigns allegiance with Mausinger in order to retrieve the Mark of Kings, an important artifact belonging to the royal family. After Roland returns to the party, they hold an audience with Mausinger in order to exchange the Mark of Kings for his cooperation, but he attacks them instead. In the occasion, Doloran takes advantage of the conflict to steal Mausinger's Kingsbond and reveals that he corrupted Mausinger's advisor, Vermine, instructing him to turn Mausinger against Evan's father. Instead of rewarding Vermine for his services, Doloran steals his soul and flees. Realizing his errors, Mausinger reforms, and agrees to treat all citizens in Ding Dong Dell equally and sign the declaration.
With four Kingsbonds in his possession, Doloran begins the ritual to retrieve his own Kingsmaker, "The Horned One", stealing the souls of people around the world in the process. In response, the party returns to Goldpaw's library where they find clues about the "Mornstar", a legendary sword capable of destroying the Horned One. After the Mornstar is recreated and entrusted to Evan, the armies of the five nations launch an attack on the Horned One to allow the party to reach and confront Doloran. Facing the party himself, Doloran reveals that Roland is his soulmate from Earth, and should one of them die, the other will perish as well. He also reveals that his true intention is not only to revive his lost kingdom but to restore his former Kingsmaker and lover, Alisandra, who was turned into the Horned One because she defied the gods by loving him. Doloran then asks Roland, whose nation on Earth was destroyed by war, to join his side, but he refuses, and the party defeats Doloran in battle.
