Event Access, Difficulty, and Equipment

Access: On Home, open the event banner below the difficulty in Stage selection. Check the event period and its unlock requirements.

Shibuya Halloween: Unlocks after clearing Gram Snowfield Ice Cave on Normal. Its highest difficulty is Spiral; no difficulty follows it. The main story's Paradox unlock rules do not apply.

Embark restriction: High-G event Equipment cannot be used in the main story until you clear the corresponding main Stage at any difficulty. Clear the Stage named in the Embark notice, remove the item, or equip a lower-G item. It remains usable in the event, and Infinite Dungeon is exempt.

Effect distinction: A normal unique property and an extra effect beginning “On event Stages, also...” are separate. Event-only extra effects do not activate in the main story.
