Masato Kato & Another Eden Begins Credits

Masato Kato is credited for Scenario / Direction on Another Eden Begins, with the main theme by Yasunori Mitsuda — two names that carry the game's Chrono lineage from the credits page straight into the marketing. Both credits sit on the official site; the studio behind the game, WRIGHT FLYER STUDIOS, is the same one that made the mobile original.

The credits we can verify

Role	Credited to	Source
Scenario / Direction	Masato Kato, with STUDIO PRISMA	Official site
Main Theme	Yasunori Mitsuda, with PROCYON STUDIO	Official site
Developer / Publisher	WRIGHT FLYER STUDIOS	Steam + Nintendo (double-sourced)

This is the short list, not a full staff roll — the store pages and the official site's credits block are what we could verify, and we are not filling in roles those pages do not name.

Who Masato Kato is, and why it keeps coming up

The game's own marketing leans on the pedigree, and reviewers follow: RPGFan frames the story as "penned by Masato Kato of Chrono and Xenogears fame."

The background, from Wikipedia's coverage of the series:

• Kato wrote parts of Chrono Trigger and Xenogears.
• He wrote and directed Chrono Cross.
• He was the writer-director of the mobile Another Eden, which he revealed as a new project at Tokyo Game Show 2015, directing and writing its scenario and script.

That last point is the one that matters for this release: Begins is not a new story by the Chrono writer so much as the same writer returning to his own mobile game's first arc and rebuilding it as a premium title. The comparison page covers what actually changed in that rebuild.

The music side

Yasunori Mitsuda's credit is for the Main Theme, and it is the element reviewers are least ambivalent about. RPGFan called the opening theme "rousing" and the rest of the tracks strong, while noting the same pieces recur often enough that the shine wears off — with seven volumes of tracks existing in the wider series catalogue that this release does not draw on.

How the writing landed

Honest summary, because this is where the game divides:

• Praised: ambition, the Chrono heritage, and the new-game-plus structure that opens up 10+ endings rather than one fixed ending.
• Criticised: the side-quest writing and pacing. RPGFan's reviewer called the added voice acting "wooden" and the plot structure disjointed; the review roundup collects the full spread of scores.

If you want the mechanical side of the cast Kato wrote — who is on the roster and how parties work — the characters page and the team and party guide cover it.
