Overview
Tsukishima Souki (月島 総記) is a novelist, screenwriter, and game creator who holds a business partnership (業務提携) with KAMITSUBAKI STUDIO. As an external collaborator rather than a full studio member, he contributes narrative expertise drawn from over two decades of professional work spanning novels, games, and anime.
He debuted in 2005 after winning the Square Enix Novel Grand Prize, launching a career that would see him become one of the more versatile writers working across Japanese media. His ability to craft compelling stories across different formats — from interactive game narratives to serialized anime scripts — makes him a valuable creative partner for a studio that operates at the intersection of music, visuals, and storytelling.
Role and Creative Position
Tsukishima’s strength lies in his adaptability. Unlike creators who specialize in a single medium, he moves fluidly between novels, game scenarios, and anime screenplays, maintaining narrative coherence and emotional depth regardless of format. This versatility aligns well with KAMITSUBAKI STUDIO’s cross-media approach to its virtual artist universe.
His involvement in high-profile franchises demonstrates his capacity to work within established worlds while bringing his own creative voice. Whether contributing to a beloved Final Fantasy sub-series or crafting original narratives, his writing consistently balances world-building with intimate character work.
Worldview Architecture and Narrative Engineering
Tsukishima Souki is KAMITSUBAKI’s chief worldview architect, novelist and screenwriter, and the original author of the flagship cross-media IP 《神椿市建设中。》.
| Dimension | Content |
|---|---|
| Role | Novelist / worldview architect / anime series composition and scripts |
| Core work | The original 《神椿市建设中。》 novel and the entire chronicle narrative |
| Narrative method | Takes the “cycle of collapse and reconstruction” as its skeleton, weaving musical works, ARG puzzles and character settings into a single timeline |
| Cross-media duties | Series composition and scripts for the orthodox TV anime, and every story branch of 《神椿市建設中。REGENERATE》 |
His place in the project: Tsukishima Souki is the actual builder of the fictional city of KAMITSUBAKI City — KAF and the other singers supply the voice and the image, while he supplies the city’s history, geography and fate.
Representative Works
- Root Double — Before Crime * After Days (visual novel franchise)
- Final Fantasy Type-0 / Agito (game scenario)
- BATTLE OF TOKYO (multimedia project)
- INGRESS THE ANIMATION (anime screenplay)
Narrative Structure and Work Index
- The original 《神椿市建设中。》 novel and chronicle: built the core settings of the city’s “singularity,” the witches’ avatars and the mechanism of “restoration.”
- The orthodox TV anime 《神椿市建设中。》: served as series composer / screenwriter, working with director Kakimoto Hiromu and the animation studio SMDE to adapt the novel’s worldview into a nationwide golden-time anime.
- 《神椿市建设中。REGENERATE》: personally handled every story branch, with multi-run world-line reconstruction (Regenerate) as the core gameplay.
- The chronicle method: using more than 500 events spanning 2018–2026 as its skeleton, it integrates the milestones of music releases, live performances, games and anime into a single traceable timeline.
Methodological trait: Tsukishima Souki’s narrative is not “writing a story for the characters” but “writing a history for the world” — the characters are the concrete projections of this city at particular points in time.
