How to Unlock
Hidden story-boss achievement in the late game — part of the endgame boss gauntlet that runs through the final districts.
Unlock
How to Unlock: Reached via late-game Key Areas; endgame enemy bands around Ebisu and Shimokitazawa are the tuning reference for the level you are expected to bring.
Boss Mechanics
Attack Patterns — Being Documented
Move list being compiled from player recordings. As an endgame fight, expect multi-column timeline pressure — several attacks queued at once, which is exactly what the pause tool exists for.
Winning Strategy
Universal Boss Framework
For heavy timeline pressure: slow time when the gauge stacks, resolve the cluster in priority order (unblockable first, Perfect Guard the rest), then cash the opening with a Soma Rush chain. Level 35 (Reaching Greater Heights) is the comfortable endgame margin.
Rewards
- Story progression
- Defeat achievement: Primordial Heavensbane
