Alegria

Alegria (喜びか, アレグリア, Areguria) is a Curse which transforms Cube.

Description
To make use of Alegria, the user swipes their hand, which causes Tartarus' mobile fortress, Cube, to turn into a monster called Plutogrim. During the transformation process, a watery substance floods the entirety of the fortress, and anyone caught in it is completely frozen in place.
