Story summary

Players T-Bit earn prizes through VR racing competitions. A network failure during a match sends him into Lunar World, a lunar server, where he meets an AI avatar named Lunar-Q.

System

The game has no storyline branches determined by options. The Steam version supports 1920×1080 resolution, with text, menus, and e-manuals switching between three languages, and supports touchscreen operation.

Connecting reality and virtual moon

The near-future VR racing game Skyout lets high school student T-BIT compete while living off prize money. He skillfully logged into the game and pursued victory, but an accident led him to an unknown lunar server, Lunar World. There, he meets an AI virtual avatar who calls himself LUNAR-Q. She was once the mascot for the lunar development project, but was later eliminated, yet she has always hoped to see Earth with her own eyes. Earth and Moon are 384,400 kilometers apart, and the two exist in the real world and server space respectively; The work raises the core question of "how to bring the two worlds closer together" from this distance.

T-BIT and LUNAR-Q

T-BIT is a high school student in real life, gaining attention and rewards through superb skills in Skyout. LUNAR-Q, whom he first met, claimed to be an AI, communicated with him through an avatar on the server, and hoped to see Earth with his own eyes; The two then met on Earth using remotely controlled Android. Later in the story, it is revealed that Q is actually a girl named Kiyu Amamiya, who lives on the moon.

A digital novel without branches

"LUNARiA" is Key's Kinetic Novel, and the story does not follow a path based on options. Players follow the story of T-BIT and LUNAR-Q through reading, dialogue, and audiovisual performances, with VR racing forming the backdrop for their encounter. The visual focus is on the contrast between the real Earth and the virtual Moon, while the narrative revolves around distance, desires, AI identities, and emotions.

Original PC and Switch versions

Key released a Japanese PC version on December 24, 2021, with a script by Tsuyoshi Matsuyama and illustrations by Fumuyun and Saeki Sora. The Nintendo Switch version, published by PROTOTYPE, launched on February 22, 2024, offers Chinese Simplified, English, and Japanese text and Japanese voice acting, and supports touchscreen operation.

Virtual images versus real identities

T-BIT's real-life identity is Traveler Roushiro, and his partner Momosaki Kon is a virtual avatar used by his classmate Hyakko Ichigaya. LUNAR-Q uses Android remotely controlled from the lunar surface during Earth activities, while its true form is the lunar-born human Kiyu Amamiya. The real identity of cat-eared player Myau Mya-fu is revealed later in the story as Ilya, and she participates in Xiyu's rescue operation.

Switch Music and System

The Switch version was released on February 22, 2024, featuring no route or ending branches, and offers Japanese, English, Simplified, and Chinese characters, as well as full Japanese voice acting including the main characters. After clearing the game, you can listen to the full versions of two theme songs: LUNAR RISE and Princess of Prism, both performed by Tsukino with lyrics by Toya Okano.

Original soundtrack carrier and twenty-five track catalog

The limited first edition released on December 24, 2021, bundled with an original soundtrack and vocal CD, was released on December 24, 2021. Key's music catalog registered the original sound as KSLA-0187. The corresponding digital release record is also recorded as October 15, 2024, with a total of twenty-five tracks, including two theme songs and "Swing by"; The latter was written by Toya Okano and composed by Shinpei Nasuno.

Original soundtrack by Shui Yue Ling and Tianxiu

Suigetsulin composed five tracks: "LUNAR WORLD -first quarter-," "A.I.," "SYMPATHIZE," "FAR DISTANCE," and "LUNAR ECLIPSE"; Ten tracks: Hisashi Amakyū composes "MOONCHILD," "COZMO," "SUNSET SEA," "DAS VIDANYA," "DAUNTLESS CHASER," "WINNING RUN," "I.D.," "HIDDEN SIDE -Daedalus-," "SPIRITUAL PAIN," and "OPERATION virtualize."

The rest of the original soundtrack production was divided among others

Soy sauce composed "KAMICO ISLE," "REAL LIFE," "VIRTUAL OFFICE," and "DEAD HEAT," while "GAMING ROOM" composed by Shuji Morifuji. In addition to "LUNAR RISE," Shinji Orito also composed "SKYOUT FOREVER," and Donmaru composed "PRISM PRINCESS" in addition to "Prism no O-o-sama"; Both theme songs have lyrics by Taya Yukano. Shinji Orito also served as the original sound producer.

AI claims to be a girl on the moon

Q initially calls herself an AI, but later reveals that she is Amamiya Kiyu, a human girl born on the moon. When she dates on Earth, she uses a remote Android device, her body controlled by the lunar surface, and her rental time is limited. Xiyu's mother, Miyu, left behind Lunar World and audio files, hoping someone would bypass the security loophole and find her daughter; T-BIT re-entered the server after Q disappeared and only learned the truth from the files.

Ilya and Lunarize

Her Cat Ear Competition rival, Myau Myaf, is actually Ilya. She helps T-BIT find the missing Q and participates in the Operation Lunerize rescue operation. The crew passes through security loopholes, overcomes power outages, and continues the rescue, but Xiyou's return capsule veers off course. In the final LAST RUN, Rabitchu reconnects with Urufun, and Kiyu is rescued; Ilya also exposes the truth Selene was hiding.

The ending theme of Swing by

Tsukino was responsible for the vocals of "LUNARiA," performing the ending theme "Swing by" in addition to the two opening themes. This song is included on track 25 of the original soundtrack, with lyrics by Taya Okano and music composed by Shinpei Nasuno.

Production of the original PC version

The original 2021 PC version was directed and produced by Taya Okano. The directors and graphic co-authors include G-Angle Co., Ltd. and Ishida Bar, with video production handled by gram6design.

Esports and lunar planning are formed

During a 2020 development talk, Koneko Daichi reviewed and asked Okano Toya to propose a Kinetic Novel with an esports theme. After several proposals were rejected, the idea of AI living on the lunar server attracted attention, leading to the creation of the "Project: LUNAR" draft combined with VR and esports. Daichi had read Tsuyoshi Matsuyama's "Iris" and "Kimi Shi ni Tamo Meteor Cluster" and felt his SF and emotional writing suited the project, inviting him to write the script.

From the first draft of the novel to the reading rhythm

In the early stages of development, Matsuyama Gou wrote freely according to the novel's style, then repeatedly adjusted based on feedback from Koneko Daichi. The two discussed weekly meetings, letting images and sounds provide some description, while the text was arranged in groups of two or three lines and the reading rhythm; Matsuyama also played Key's works, learning how much information each paragraph should contain.

Animal themes with virtual characters

According to the 2021 key animation log, Fumuyun is responsible for the wolf-themed T-BIT and the rabbit-themed LUNAR-Q, while Sora Saeki is responsible for cat ear myou and fox ear kon. T-BIT once had ear and tail designs, but since it easily looked like a costume, it was abandoned and replaced by hair and plush details; The floating decoration on Q's head is rabbit ears.

Moon and Earth imagery in 2021 PC packaging

In his January 2022 diary, Fumuyun explained that the 2021 PC packaging had LUNAR-Q leap from the moon, representing Earth with blue petals; The blue disc inside the box also features the Earth imagery. From packaging to CD unfolding, a visual design connecting the moon to the earth is created.
