ONE

Plot
ONE takes place four years after the events of OFF if the Player/Puppeteer were to choose the Official Batter's ending.

The beginning narrative follows Zacharie as he tries to survive the onslaught of new monsters that have appeared ever since the Batter had flipped the switch. However, Zacharie begins to feel lonely due to being one of the only survivors left from the Batter's purification.

In an attempt to escape his loneliness, Zacharie uses the Grand items given to him by the Batter, and he creates new life in the form of a child, whom he names Doux.

After the epilogue, the Player is then assigned as Doux's puppeteer. Doux is quite excited about this, and he decides that he wants to introduce the Puppeteer to his father, Zacharie. Zacharie, however, is unsure of letting his son become a puppet because of the Player's former partnership with the Batter, but eventually he comes to accept it.

Some point afterwards the tutorial, Doux wakes up to find that Zacharie is gone. It is here that the actual game begins, and you are in charge of leading Doux in his self-appointed mission of finding his father.

Doux
Doux is a kind-hearted child with a very lovable, affectionate, and loyal personality. Unlike in OFF, where the Batter "purifies" any whom he comes across, Doux spares certain NPC's after his fights. He is even willing to befriend his enemies after a fight as well. Though Doux has not properly learned how to read as he is still very young, he tries his best to make out the words and read them to the Player. Most of the time however, it is up to Blight and the Puppeteer themselves to read the text. When Doux lets his anger get the best of him, he starts to become burnt just like an Elsen does. This is because he is not human, but instead made of the five Grand Elements given to Zacharie by the Batter. Because of this, Doux has to control himself from becoming too enraged, lest he may be lost forever.

Zacharie
The previous merchant in the world of OFF and Doux's father. He was taken to The Room by Gouette in zone 0, and was trapped there. The story of ONE revolves around you trying to rescue him.

Blight
A temporary merchant (and party member later on) that was created in Zacharie's image. Because of this, he retains some of Zacharie's memories like Pablo and Valerie. He wields a sword much like the masked man in the book about the Toad King.

Dedan
The previous guardian of zone 1, now replaced by Chahal. After being killed by the Batter, he has understood his wrongdoings and has become more caring and friendly.

Japhet
The previous guardian of zone 2, now replaced by Oculi. He too has had time to reflect on his past after being killed, and is more understanding and patient. He also lets the player pass to the rest of his library after zone 3 is re-purified.

Valerie
The brother of the Judge, who resides at the top of the great library as a ghost. He entrusts Doux with reviving his brother by giving him an Ace and his brother's body.

Enoch
The previous guardian of zone 3, replaced by Hathath, a creature of nightmares. He appears to be acquainted with Viola, as he entrusted her with the key to his hideout in A4.

Viola
A merchant that mysteriously appears after Blight becomes a party member so that "He doesn't sell stuff to himself out of his own inventory". She too appears to be created similarly to Blight and Zacharie.

Bosses
Gouette

The being sent to zone 0 to rebuild it. However, according to Chahal, he was simply dead weight, and didn't intend to rebuild his zone at all.

Chahal

The being sent to zone 1 and one of Blight's older siblings. He resides in Alma and forces the Elsen spectres to serve him loyally by bringing him food nonstop. In return he says that the most hardworking spectres will be allowed access to his "New World". In reality, however, he has done almost nothing to rebuild his new zone, and its inhabitants live in constant torture from the cold.

Oculi

The overseer of zone 2 and Blight's older brother. He too has corrupted most of his zone apart from the great library, and resides at the top of a doppelganger tower he built behind the residential area.

Hathath

The being sent to zone 3. He corrupted all of zone 3 with his nightmares and created 2 nightmare rooms in A4 for the player - The Playroom and The Toad King nightmares. He also created an entirely new area in zone 3 - A5 - for him to reside in.

Gameplay
The gameplay replicates OFF's, just as most traditional OFF fangames do. However, any character who is not a canon OFF character has their own set of new moves to use within ONE.

Trivia

 * Apparently, Doux's birthday is September, 4th.
