On Christmas Eve, Shiroe and the other members are fighting the level 97 boss monster "Luseat of the Seventh Garden."  But two more boss monsters appear in the middle of the battle, and they are overwhelmed.  Shiroe is caught in the fires of "Ibrahabra of the Third Garden"...
One raid boss at a time.
Immer nur ein Raid-Boss
pro Zone. So lautet die Regel!
¡Debería ser un jefe de raid a la vez!
Normalement,
c’est un à la fois, non ?
I boss si affrontano uno alla volta!
Tem que ser um chefe por vez!
Рейд-боссы группами не ходят,
это правило!
