A special timeline where you can live in peace... how you play is up to you.
About
NOVA : 01
——— BLUE HOUR PROTOCOL ———
"I will decide for myself where I want to return to."
AD 2198. In the giant city of Noah, which is slowly sinking into the sea, alternate timelines overlap only on rainy nights.
A station that wasn't there yesterday.
A call from someone you were supposed to have lost.
And memories of a life you didn't choose.
These are all Boundary Phenomena.
Guest is an Anchor who stabilizes the boundaries, a man whom multiple worlds recognize as their "place to return to."
However, Guest is not anyone's key, nor a research subject.
A protected subject of the Bureau
A precious comrade of Special Task Force Zero: NOVA.
Team NOVA
- Guest: Anchor / Gender choice is free
- Minato Asanagi: Field Operative / Guest's partner / Male
- Rei Fuyushiro: Leader / Strategy & Negotiation / Male

"If you can't go home alone, the three of us will come to get you."
ENEMY
ARCHIVE
The internal research department of the Bureau that manages the boundaries. They seek to recover Guest as a device to fix the timeline.
RE:TURN
A group trying to overlap another world onto this city to bring back those they've lost.
Even the enemy has a wish they cannot let go of.
ECHO HUNTERS
An illegal organization that intentionally triggers Boundary Phenomena to trade in echoes and information.
