Event Announcement and Collaboration PV

The Collaboration Starts After August 28 Maintenance

The event opens after maintenance on August 28, 2026. Ayakashi Rumble has not yet provided a specific maintenance completion time or an end date for the crossover.

The full title, Nora to Ikyo to Ayakashi Ranbu! ~Neko no Fushigi na Bokentan~, has also been confirmed through the official PV, framing the crossover around Nora and a mysterious cat-themed otherworld adventure.

Yuuri Shachi Appears on the Limited Tsuiso Shinkei

One confirmed participation reward is a limited 追想心景 (Tsuiso Shinkei).

Its announcement artwork features Yuuri Shachi alongside a black cat and displays the wording “限りない慈愛.” The current reveal does not specify its rarity, stats, effects, or whether this particular reward includes a dedicated episode or animation.

Shachi appearing on the reward should also not be treated as confirmation that she is a playable collaboration unit. That lineup has not been announced yet.

Nora Brings the Netherworld Into Ayakashi Rumble

Nora to Oujo to Noraneko Heart follows Nora, whose life changes after meeting Patricia of End, a princess from the Netherworld.

Magic, the realm of the dead, and Nora's transformation into a black cat have been central parts of the franchise since the original visual novel. The new event title itself directly references a “mysterious adventure of a cat.”

Yuuri Shachi is one of the source game's central heroines, living with Nora and taking care of his household while being known for her calm temperament and cooking.

Gacha and Playable Units Are Still Secret

The August 26 announcement focuses on the event schedule, PV, and participation reward.

There is currently no confirmed collaboration-summon lineup, character rarity, skill information, stats, or complete list of Noratoto heroines that will appear as playable units.

The event boss, dedicated currencies, complete reward pool, and ending date are also still undisclosed, leaving the post-maintenance announcement to provide the mechanical details.

Ayakashi Rumble Remains Available on PC and Mobile

Techcross develops and operates Ayakashi Rumble, with the game distributed through DMM GAMES / EXNOA.

It is available through PC browsers, the App Store, and Google Play as a free-to-play title with in-game purchases. Players take the role of an onmyoji and fight alongside a roster of shikigami through its skill-based battle system.

Ars Mechanica

The Noratoto crossover becomes one of the game's newest events heading into the end of August 2026.

Why This Matters

1) Noratoto returns through an active game crossover

The visual novel franchise that began in 2016 is appearing again through a new live-service RPG event.

2) Yuuri Shachi receives immediate attention

Rather than only revealing crossover logos, the first major announcement already gives players a concrete participation target through a limited Tsuiso Shinkei featuring Shachi.

3) Both franchises already lean into the supernatural

Ayakashi Rumble revolves around onmyoji and supernatural beings, while Noratoto brings in the Netherworld, magic, and Nora's black-cat transformation.
