Main protagonist of [[otome_game_no_hametsu_flag_shika_nai_akuyaku_reijou_ni_tensei_shite_shimatta |Hamefura]]. She has [[blue eyes]] and [[long_hair|long]] [[brown hair]].

An otome-game loving otaku who was reincarnated into the setting of her favorite game as the villainness that always suffers some sort of cruel fate. She does all she can in a desperate attempt to reverse her doom, entirely oblivious to the fact that her efforts are fundamentally changing the character, as the arrogant, haughty and cruel Katarina is entirely replaced with her own somewhat childish, honest and caring personality.

[spoilers]Her former incarnation is a [[monkey_girl_(hamefura)|currently unnamed]] school girl.[/spoilers]
