Crusch Karsten/Relationships

Ferris
Crusch and Ferris have been extremely close ever since they've met when they were still children. Ferris stood by her side ever since, supporting her and helping her out to his best efforts. Their relationship was very personal and almost intimate, considering that they have never been seen in a conflict. Crusch has said things such as "You are truly the one who knows my heart best" to Ferris, further showing their close and strong relationship. Ferris in turn has been shown multiple times to have feelings deeper than close friendship for Crusch.

Ferris even showed jealousy when Crusch had dinner with Subaru because according to him, they were having dinner in the same way that Crusch did with him.

After Crush had her memory eaten by Lye Batenkaitos, her relationship with Ferris became more one-sided, with Ferris becoming more protective of Crusch. This reached a point where Crusch put a stop to his attempt in breaking their alliance with the Emilia Camp just to protect her from the Witch Cult, which would inevitably confront Emilia due to her resemblance to the Witch of Envy.

Natsuki Subaru
Though her original impression of him was lacking as a result of Subaru's initial outburst before the Royal Selection began, she later served as a benefactor to Subaru when she allowed Ferris to treat his gate. However, once Subaru revealed information about and later served as an instrumental part in slaying the Hakugei, she gained respect for his abilities and gave a large portion of credit to him. After Lye Batenkaitos ate her memories, the two of them would still hold mutual respect for each other.
