GRIMOIRE indefinitely pauses activity
10th anniversary live is held.
GRIMOIRE was a visual kei band in Tokyo. They were part of the cosplay kei subgenre. They were active from 2015 to 2022 and are currently paused.
Upon looking at multiple sources, I only see Mel having been in one band before GRIMOIRE and that was 超時空アンドロイド-PIECE-. But I am unsure what is correct, so there won't be any edits yet.
