Se.Ra.Ph (Fate/Grand Order) Wiki

Abyssal Cyber Paradise, SE.RA.PH

"A resort event? You thought this would be a walk on the beach?
Welcome, all you foolish Masters!
The fate of the world rests in your silly, useless hands♥"
Our stage will be the Offshore Oil Rig, Seraphix, now a hellish recreation of the Moon Grail War.
This is a cage of ecstasy from which only one can escape.
Only moments remain until the base disintegrates.
And what is it that lurks at the bottom of this dance of Egos...?

Original Description

"Spring break means it's time for a trip!
It's a little early, but how about a beach event, foolish humans?"
The sudden arrival of the demonic digital brain BB throws Chaldea into a chaotic spring vacation.
A sweet, heated catfight ensues.
Fragile, pure, and sexy...
Look forward to an unforgettable resort event!

The extra pseudo-singularity in Fate/Grand Order, set in the Chaldea Security Organization's Seraphix oil rig, which has been displaced into the Mariana Trench in 2030 and transformed into a space resembling the Moon Cell from Fate/EXTRA CCC. It was initially presented as a collaboration event between Fate/Grand Order and Fate/EXTRA CCC, only to be revealed as a pseudo-singularity upon the event releasing.

Released on the Japanese server on May 1, 2017 and on the NA server on April 23, 2019. BB is given as a reward to players for completing the event. It was adapted into a manga by Nishiide Kengorou.
