Dagon

A Disaster curse: humanity’s collective terror of the sea, given teeth. At Shibuya, a dead man crushed it inside its own domain, an insult no curse has ever survived twice.

The Games dragged it back anyway. The barrier does not care what died embarrassed.

The Raid

Dagon’s domain is an endless shoreline, and the tide is the timer. The water rises through the entire fight. Ground you held in minute one is gone by minute five. Kill it before the shore runs out, or learn what its shikigami do to swimmers.

Mechanic	Threat
The Rising Tide	The arena shrinks continuously; the tide is the enrage timer
Death Swarm	Fish shikigami flood the shallows
Horizon Wave	A periodic arena-wide wave that must be high-ground dodged

Rewards

Tide-forged weapons, Dagon’s raid crate, and drowned-court cosmetics.

What it means

Seimei was brought back on purpose, a hire. Dagon is worse news: the Games are now reviving things no one asked for. The barrier is not a guest list anymore. It is an open door.
