Schadelerian Infection

"With New Meridian being under attack by Eloise Scarletvoid, the Schadelerian Infection had begun to destroy the Black Egrets, the Bioterrorism Security Assessment Alliance and the rest of the GRand Alliance. It looks like the South Vietnamese Umbrella Force had rolled their tricks up to their sleeves."

--Su Ji-Hoon, A Train to New Meridian

The Schadelerian Infection is the infection event that New Meridian has been under attack and infection by Skullgirl Eloise Scarletvoid and her undeads with the WhiteKnight B.O.W.s and South Vietnamese Umbrella Force

Only happened after the Zeltwachen Infection after Medici Mafia joined Ducangers due to prevent being weak that the Army of the Republic of Vietnam and South Vietnamese Umbrella Force deployed their WhiteKnight B.O.W.s with the assistance of Skullgirl Eloise Scarletvoid and her undeads to attack New Meridian, a city from Skullgirls game.

Therefore, the Medici Umbrella was born that they become new rival of Black Egrets and the Bioterrorism Security Assessment Alliance in this infection.
