"Dere types" are like tsundere, yandere, etc.
Catherine - Has a cat theme but isn't literally a cat. She is treated like a cat and a tool by the antagonists that traumatized her. At first, she acts sweet and kind with a very disturbed, traumatized interior and acts distrustful to Belle (who has a black cat motif) but later warms up to Belle.
Belle - Belle's exterior is like a black cat -- shy and aloof. She, too, acts cautious and distrustful to Catherine, but ends up dating her before breaking up with her after realizing she thought she was in love, but never was. (They both find someone later).
Dominique - Dominique, at first, seems like a friendly and shy girl. She is very patient and kind, and appears as “one of the good ones” to Catherine after Natasha’s mistreatment of her. However, Dominique is actually best friends with Natasha, and is very violent. She screams at Catherine, insults her, and says she just wants Catherine to “shut up and die”.
Natasha - Natasha is one of the “owners” of Catherine, who she decides to treat as a “pet” because she reminds her of a cat (hence the name CATherine). Natasha and her friends invite Catherine into the friend group and they all live together, but Catherine is treated badly there and Natasha makes a plan to kill Catherine. She is very fake and manipulative, and at first is very sweet, ladylike, and kind, before revealing it to be a facade.
Nora - Nora has a bear theme. At first, like a bear, she is rather violent and plans to kill her love interest. However, she begins to show a dere side after warming up to her and no longer wants to violently attack her.
I didn’t try yet 😭 Maybe I should though
