As the Day of San Valentino approaches once again for this year, a strange atmosphere blankets the corridors of Chaldea…
Archnemesis, bitter enemies and rivals alike suddenly mingle between one another in a friendly and harmonious way, much to your surprise.
Maybe it’s just the effect of the Valentine’s?
Unfortunately, a sudden appearance of Shadow Servant-like beings overrun the Chaldea, of which you had a hard time to deal with due to them constantly reviving upon defeat.
Even your premier anti-Shadow Servant Archer, the Valentine’s Servant from last year, Sei Shonagon, having trouble to deal with them as well…
Out of no where, an unknown Servant appears before you, stating those things, now dubbed “Bitter Shadow”, can only be destroyed using the power of Love.
Together, you’ll now grind the Valentine’s event of Fate/Grand Order for the next 2 weeks! :P
