Duet Night Abyss officially launched its latest major update, Paradise's 22nd White Bunny, on September 8, 2026 at 4:00 PM JST. Its headline additions include the continuation of the Twilight Arc, the new Mount Arcano region, the Pyro character Falsi, three weapons, multiple events and skins, and a broad set of quality-of-life improvements.
The story also takes a noticeably darker turn. Arcano is a region devastated by war, leaving behind a former tourist town and an abandoned amusement park. In a place that should barely support human life, the protagonist instead discovers a community living under the rules of Rabbit Mama—and hears claims about childhood memories they do not remember.

PV, Steam and the World of Paradise's 22nd White Bunny
Arcano Turns the Idea of Paradise Into Something Unsettling
The new region is located on Mount Arcano, part of the southern mountain range of Flagson that was caught in the war between Hyperborea and the Elysian Church roughly four years earlier.
Human activity has largely disappeared from the area. AUTOMATON's hands-on report describes Arcano as the remains of a former tourist destination, with reddish-brown terrain and vegetation slowly reclaiming its abandoned structures.
The amusement park is its most striking landmark.
A Ferris wheel, teacups, roller coaster and other attractions remain standing, but the result feels more disturbing than cheerful. Attractions originally designed for entertainment are surrounded by silence, ruins and an increasingly strange story.
Officially, the protagonist enters the area while searching for the “catalyst” previously mentioned by Avar.
There they encounter a community controlled by Rabbit Mama. Residents wear name tags indicating their status and follow a tightly regulated daily routine.
The deeper the investigation goes, the less convincing the town's supposed “paradise” becomes.
Ada (??) Claims to Be the Protagonist's Childhood Friend
One of the chapter's stranger elements involves Ada (??), a character introduced in the previous version.
According to AUTOMATON's preview, Ada approaches the protagonist while claiming to be a childhood friend and guides them around the ruined amusement park.
The protagonist, however, has no matching memory.
Other residents go further, claiming that the protagonist once lived in Arcano as a child. Without reliable memories of that period, there is no easy way to confirm or reject what they are saying.
Even the “(??)” attached to Ada's name remains part of her mystery.
Lost memories, a community behaving a little too peacefully, the abandoned amusement park and Rabbit Mama together give this chapter a stronger psychological-mystery atmosphere than a straightforward trip into a new region.
Falsi Is a Pyro Assassin Built Around Risk
The update's major playable addition is Falsi, voiced in Japanese by Asami Imai.
Official information identifies her as a Pyro character associated with the Imperial Army 13th Legion, with proficiency in Dual Blades and Dual Pistols.
AUTOMATON's development-build preview provides additional story context. Falsi is portrayed as a former soldier and assassin who performed the empire's dirty work.
She once placed absolute trust in a senior officer named Fulvis, who convinced her that she was different from other Charon.
After Fulvis betrayed her during an incident that nearly killed her, Falsi realized she had also been treated as a disposable pawn.
Her guilt over the people she assassinated and her desire for revenge against Fulvis now form major parts of her characterization.
In the preview build, Falsi's combat also deliberately plays around low HP. Dual Blade attacks can inflict self-damage, while one of her buffs becomes stronger as her health drops.
Shadow Strike can deal damage while restoring HP.
Because those mechanical observations come from a pre-release build played by AUTOMATON, final tuning may differ, but the high-risk/high-reward concept clearly complements her self-destructive assassin characterization.
Three New Weapons Enter the Rotation
The update introduces several new weapons.
Stifled Howl is a Dual Blades weapon obtainable through Forging or direct purchase. Its relevant Secret Letter enters the initial Immersive Theatre rotation.
Sanguis Sanctus - Whipblade expands the Whipblade category.
Sanguine Plume, meanwhile, is a Calamity Weapon using Dual Guns, with its acquisition entering the relevant activity and Memento rotation according to the version schedule.
The Japanese update uses 声なき叫び, 〖聖血〗ウィップブレード, and ブラッディレイヴン for these three weapons.
They continue Duet Night Abyss's core acquisition philosophy: characters and weapons can be earned through gameplay instead of requiring a conventional character or weapon gacha.
Skins, Events and Rewards Expand Alongside the Story
Falsi receives the limited Black Artemis / 漆黒のアルテミス skin through the Myriad event “Where the Long Road Leads,” running from the September 8 update until October 19, 2026 at 6:00 PM JST.
Berenica and Psyche also receive doll-themed skins through Capriccio of Whimsy, while a police-themed Urban Code / 都市の鉄則 cosmetic line is available for multiple characters.
New mounts are also being added through the Prism Shop alongside activities including Parade Itinerary, cumulative login event Way of the Penitent, Treasure Hunt Trials, Vibrant Strokes, and multiplayer content.
Logging in for seven cumulative days through the relevant event awards a total of 10 Prismatic Hourglasses / 彩りの砂時計.
Some events run until October 19, while others have shorter schedules or begin later in September.
Players should therefore check individual event notices instead of assuming every piece of version content shares the same end date.
QoL Changes Reduce the Grind and Multiplayer Friction
A significant part of Paradise's 22nd White Bunny is focused on quality-of-life improvements.
A new Matching Lobby helps players find teammates based on what they want to play.
Immersive Theatre: Ensemble Act receives additional free room-creation opportunities and changes to its reward structure.
A new proficiency-expansion item can give a character one additional weapon proficiency, expanding their available choices from two weapon categories to three.
For farming, the update adds consecutive-battle functionality and automatic companion combat to reduce repetitive input.
Earlier quest access, additional Forging filters, easier permanent free-character acquisition and automatic fishing are also among the improvements.
AUTOMATON additionally highlighted changes to Immersive Theatre as particularly useful for newer players, since character acquisition is less dependent on building several teams around rigid seasonal weakness requirements.
The result is an update designed not only to add content, but also to remove some of the friction around progression.
Why This Matters
1) The new story is willing to become genuinely unsettling
Arcano uses an amusement park and the language of “paradise,” then deliberately undermines both through ruins, social rules and unreliable memories.
2) Falsi connects characterization with combat design
Her destructive assassin background is reflected in a playstyle built around self-damage, low HP and carefully timed recovery.
3) The free-character model remains intact
Falsi can be earned through gameplay, while new weapons likewise have gameplay-based acquisition routes.
4) The QoL work targets progression rather than only cosmetics
Matching Lobby, expanded weapon proficiency, automated farming and Immersive Theatre changes directly affect everyday play.

Closing

The update also attempts to reduce progression friction through multiplayer, farming, weapon-proficiency and Immersive Theatre changes. The mysteries surrounding Rabbit Mama, Ada (??) and the protagonist's past can now be explored directly because the new main-story chapter is permanently available.
