Regina

Regina (レジーナ) is a minor goddess that presides over manipulation and revenge. As of Seresdina's conversion to the Axis Faith, she no longer has anymore known followers and has presumably been wiped out of existence.

History
Regina used to be sealed at the Crimson Magic Village due to the clan stealing the relic she was in as a part of a collection to show to tourists. She was later unknowingly released by Megumin when the latter first used Explosion magic, and fled to an unknown area after release.
