Sovereign Mode is an opening choice that uses autosave and disables ordinary manual Save/Load. Mistakes are intended to be handled through Demon rewind, so the mode changes save management rather than combat or multiplayer. The full autosave timing and any special reward remain not fully documented.
What the sources confirm
Multiple formal-release walkthrough sources describe Sovereign Mode as autosave-only with manual saving and loading disabled. The player is expected to use Demon rewind for major decisions, and the game remains a single-player Narrative/RPG/Visual Novel experience. The mode should not be described as a separate battle mode or late unlock.
How to use this information
Explain Sovereign Mode as a save-management challenge before a player selects it. Link the time-rewind guide because the mode increases the importance of timeline decisions. Do not add precise autosave nodes, file-copy workarounds or rewards unless the current game UI or official documentation confirms them.
Why this query matters
This resolves the keyword from a terminology mix-up into a real feature, while keeping its scope narrow. The important player-facing difference is how save behavior changes the cost of decisions. It is not evidence of multiplayer, extra combat rules or a hidden reward.
Known limits
Exact autosave timing, Alt+F4 or file-copy bypass behavior, hidden rewards, any Ending relationship and all mode-specific consequences are not fully documented. One player report of no separate reward is not enough to prove that no hidden reward exists. Do not expand the mode beyond the confirmed save-playstyle distinction.
Source filter
The 1.0.8 research adds current formal-release evidence that Sovereign Mode is a save-playstyle choice. Official store descriptions still do not document every rule, so the page distinguishes existence from mechanics.
