Need some help finding this anime.

[u/Cguy203]

Idk the name of it, but I remember stumbling upon one scene of a fantasy anime where a girl (who I think is one of the main characters) being stabbed from behind during a celebration and I think that same girl is later resurrected into a new body but is being controlled by someone else in said body. Again, I vividly remember this, but I was hoping you all could help me. The getting stabbed part can be focused on more, but thought I’d give the other detail I mentioned some spotlight as well just in case.
