Official Announcement, Steam and BLUE BITE's 3D World

The Only Man in a World Threatened by Bluebite

BLUE BITE begins with Tsuzuru Chigusa arriving in another world inhabited entirely by women. Within that setting, he is described as the only surviving man.

The world is approaching extinction because of bluebite, a mysterious disease that can stop women's life functions and sits at the center of the game's main conflict.

Tsuzuru is then entrusted with a treatment by a goddess. BLUE BITE's premise identifies that method as a massage technique, and players will use it to help people suffering from the disease.

The story extends beyond simply locating patients, however. The official website also teases a truth spanning time and space behind both the world and bluebite, making the treatment system an entry point into a larger mystery.

13 Chapters, Six Endings and More Than 100 Hours of Fully Voiced Dialogue

The main narrative is presented through Adventure Mode, which follows the protagonist's point of view and focuses on his relationships with six heroines.

The official announcement describes a 13-chapter multi-ending story, while the official website more specifically promises six different endings tied to its heroine routes.

One of the largest production figures being promoted is more than 100 hours of fully voiced dialogue.

That wording is important: ULTRANOVA is confirming the amount of voiced dialogue rather than stating that a single playthrough necessarily takes more than 100 hours.

Player choices can change each heroine's affection. Those values affect the ending, while heroine-specific side stories, special expressions, event CG and scenes unlocked under particular conditions form part of the progression system.

Mission Mode Opens Cities and Resorts for Direct Exploration

BLUE BITE is not presented purely as a visual novel or text adventure.

Mission Mode allows players to directly control Tsuzuru and move through 3D environments. Objectives can include traveling to a specified destination, finding people showing symptoms of bluebite and carrying out treatment as the story progresses.

Additional environments unlock over time. Official material describes locations ranging from deep urban districts reminiscent of modern Japan to a tropical resort.

Players can also speak with heroines while exploring. These conversations may reveal sides of their personalities that are not shown in the main story, keeping exploration connected to the relationship system.

The two-mode structure therefore divides BLUE BITE between branching romance and dialogue in Adventure Mode and objective-driven 3D exploration in Mission Mode.

Six Heroines Are Led by a Six-Member Voice Cast

The official website and press release consistently position six heroines at the center of BLUE BITE's relationship system.

Himari, voiced by Yuka Hinata, is introduced as the protagonist's highly capable personal maid.

Enju, voiced by Ringo Aoba, is a quiet and mysterious shrine maiden who tends to keep her distance.

Asebi, voiced by Tomoe Tamiyasu, is a cheerful bunny girl and the manager of the Bunny Bunny lounge.

Rindo, voiced by GEMIKO YAMADA, is an energetic police officer with a strong sense of justice.

Mayumi, voiced by Ayaka Igasaki, is presented as a calm and mature science teacher.

Finally, Ran, voiced by Kaede Akino, is a serious tsundere girl who often serves as one of the group's more grounded personalities.

There is one additional wrinkle in the Steam overview reproduced by Gematsu: its “Main Characters” list also includes Planta, voiced by Izumi Mikoshiba. The official website and press release, however, continue to identify exactly six core heroines and do not include Planta within the current six-heroine profile section. This article therefore does not count Planta as a seventh heroine until ULTRANOVA further clarifies the character's role.

Production Has Passed ¥100 Million, With tomozero on Character Design

BLUE BITE's announcement has also drawn attention for the scale of its production.

Stranded with You

The official announcement states that production costs have exceeded ¥100 million. No final figure or budget breakdown has been published, so the confirmed claim is only that production passed that threshold.

Illustrator tomozero designed the six heroines. The press release emphasizes small visual details across their costumes and even their nails, while the introductory character illustrations used for the announcement were also newly drawn by tomozero.

On the narrative side, Katsunori Kobayashi is credited with the original story / scenario concept, while Yasuki Hujihara with KIKAKUYA handles scenario writing.

ULTRANOVA Entertainment itself operates as a game brand of Suiseisha, a company whose business also includes comics publishing, anime production, Blu-ray/DVD sales and animation-related projects.

Steam Wishlisting Is Open Ahead of Tokyo Game Show 2026

The BLUE BITE Steam page opened for wishlisting alongside the September 10 announcement.

The game will also appear at Tokyo Game Show 2026, running from September 17 through September 21 at Makuhari Messe. ULTRANOVA's exhibit is located on the North Entrance side of Exhibition Hall 2.

Its booth is being designed around the urban environment reproduced as a 3D map in the game. Cosplayers Shionomeri and Nana Matsuoka are also scheduled to appear in costumes inspired by BLUE BITE heroines.

On platforms, PS5 and Steam are explicitly confirmed. The English website currently says “PlayStation 5 / Steam and more,” but the additional platforms have not yet been named.

Pricing, a specific release date, preorder information, official age ratings such as CERO or ESRB, and PC system requirements also remain unannounced in the verified material.

Steam currently uses an age gate and carries a mature-content description mentioning revealing outfits or swimsuits and some mature illustrations, poses and voice material. That description should not be treated as an official age rating.

Why This Matters

1) Romance and 3D exploration are built as two distinct core systems

Adventure Mode handles relationship choices and branching narrative, while Mission Mode lets players explore maps directly and complete objectives.

2) The amount of voiced material is unusually prominent

More than 100 hours of fully voiced dialogue stands out alongside a 13-chapter structure and six endings.

3) Six heroine relationships directly influence the ending

Choices do more than change individual conversations; affection values influence route outcomes and the scenes players can unlock.

4) The announcement immediately comes with Steam and TGS presence

BLUE BITE was revealed with an official website, Steam page, screenshots, cast, gameplay systems and a Tokyo Game Show booth rather than only a name or early teaser.
