Wait, Rikako is in Danganronpa 2, and Kazumi might be from another series. Wait, maybe the user is referring to the Danganronpa 2 characters Rikako Aomori and Kazumi Mafuyu? Or maybe Kazumi is another name. Let me confirm. Rikako Aomori is in Danganronpa 2: Goodbye Despair. The female protagonist in Danganronpa 2 is Rikako Aomori. There are also other characters like Kazumi, but I'm not sure. Wait, maybe the user made a typo? Kazumi could be a typo for Rika, like Rika Orimura or someone else.
