That's because it happens in Vega and Altair route. Yuki is studying in Germany in this worldline and Leskinen has Kagari replace her and infiltrate the lab so that he follows what Okabe does or something like that. He had her go through plastic surgery in order to look like Yuki. Kagari is probably ok with it as it allows her to be at the sides of Mayuri.

The anime does take a completely different route during Vega and Altair so there is no Kagayuki, it's always Yuki AND Kagari. For that reason, the reason she cries when she takes Daru hostage differs from the VN.
