Do you need to know Rainblood before playing?

Direct answer

No official source says prior Rainblood knowledge is required. S-GAME calls Phantom Blade Zero a spiritual rebirth, which signals creative lineage rather than a confirmed prerequisite sequel.

What is not confirmed

This answer is intentionally limited to what the cited primary source establishes. It does not rely on fan-maintained lists, retailer placeholders, edited trailer cuts, leaks, or assumptions imported from other action RPGs.

How this answer will be updated

The page will be checked after the dedicated summer State of Play, material store-page changes, and the retail launch. New details will be added only when they answer this exact question; separate search intents will keep their own URLs to avoid overlap.
