The Controlling Organization branch in Akitsu-Kō was destroyed by Ragna the Bloodedge in the year 2198, this event was shown in the first chapter of BlazBlue: Chimelical Complex and the first episode of Alter Memory. This is later shown to have a startling effect on the ecosystem as the environment maintenance device of Akitsu can no longer control the weather properly, causing large amounts of snow to pile up. In BlazBlue: Chronophantasma, it was resuscitated by Relius Clover.
