Environment maintenance device

Environment Maintenance Device (環境維持装置) is a device that controls the weather, utilizing magic element to operate. It is implied that every Hierarchical City has one.

In chapter 7 of BlazBlue: Remix Heart, the incomplete Regulation Grimoire caused the Magic Formula of the 15th Hierarchical City "Torifune"'s environment maintenance device to go haywire, so the city was covered in snow.

Due to the destruction of the Kiln in Snow Town of Akitsu-Kō by Ragna the Bloodedge, their device can no longer control the weather properly, causing large amounts of snow to pile up. This device also affects weather in its sister city, Akitsu-Otsu, but Otsu has a desert instead of snow.
