BUR #59457 is pending approval.
mass update favgroup:55442 -> Decagrammatonization
Corresponding tag on Pixiv is デカグラマトン化.
Refers to the concept of character in Blue Archive being corrupted or transformed into a member or "Prophet" of the Decagrammaton (Blue Archive) faction. Typically involves appearance features like white skin, white hair, yellow eyes, and x-shaped pupils.
Still, the term "Decagramatonization" seems a bit too long or obscure; Mabye should use some alternative like Decagrammaton Conversion?
