Eruza appears to be a young girl (a high schooler to be exact) with a slightly short stature, small chest, shoulder length caramel brown hair tied in short twintails with a pair of sphere-shaped ornaments and brownish-orange eyes. When transformed, she has a pair of fluffy cheetah ears and tail, cheetah claws and feet as well as sharp teeth. She also wears a cheetah print tube top and sarong during the Destroyale
She's a little childish, naughty and quite playful, as she stole Hitomi's panties and ran away gleefully with them just to make the former chase after her. Eruza has very keen interest on Hitomi, one that's borderline sexual proven by her constant advances on her, specially during the nekomimi maids photo session. Interestingly, she also sees her as a potential rival ever since she caught wind of Yugo's defeat at the hands of Hitomi, specially knowing that the former is her brother's rival. She was envious, as well as shocked, when she got to know that Hitomi lived with Nomoto, a college student. She doesn't think too highly of him.
Eruza loves and greatly respects Taiga, as he's the only family she's got left. She was quite concerned over Taiga's wounds after his defeat against Takeshi Kido , and wanted to get him to the hospital as soon as possible.
Eruza is the younger sister of Taiga and represents the Yatsubishi Zaibatsu alongside her brother Taiga. She first meets Hitomi when she transfers to Yuya’s university. Both end up wearing cosplay in an attempt to cover up their Hybrid identities while students from the photography club photograph them.
When the Destroyal begins, Hitomi meets Eruza's older brother Taiga. It is there she expresses desire to kill Hitomi. Eruza is maneuvered into an area not covered by the camera, allowing Kaede Kazama (a Gecko Hybrid) and Den Onuma (a Cobra Hybrid) to restrain her with Den intending to rape her only to be saved by Hitomi who had been moved there by Yuya to save Eruza and promptly attacks Den. Having being distracted by Hitomi, Den's face is then slashed by Eruza who wounds him in retaliation. Reluctantly deciding to team up, Eruza fights Kaede while Hitomi decides to fight Den. During the fight, Kaede further transforms into a monstrous Gecko and overpowers Eruza; but Den is defeated after Hitomi incapacitates him by slicing off his genitals before the two confront Kaede who chooses to flee rather then face the two at once on her own.
Just as Eruza and Hitomi are excited to finally have their confrontation, they suddenly find themselves kissing each other lustfully in the midst of their duel. They find the cause of this is due to be drugged by a new rival by the name of Kaori Rikujo, a Civet Hybrid from Yatsubishi who can produce a pheromone that causes uncontrollable lust. Hitomi then manages breaks free from the lust by focusing on her real lust for Shidoh.
When Takeshi Kido is on his death throes, a recovered Eruza suddenly slashes his throat, finally killing him and making her the Killing Bites Champion.
An unconscious Ui Inaba suddenly awakens before Eruza notices her and chases after her. As she tries to flee from Eruza, she accidentally performs a perfect somersault kick; knocking Eruza unconscious. Overseer Shinozaki declares Ui the Killing Bites Champion.
After losing the final match of the first Destroyal against Ui in such an unexpected way, her main purpose from then on has been to get vengeance against her for having been humiliated in that occasion.
AbilitiesEditBrute Transformation- Having the characteristics of the Cheetah, Eruza has the speed and nimbleness far surpassing those of a human. She also counts with razor sharp claws that allow her to deliver fatal strikes. A particular trait to her transformation is that Eruza's body is capable of withstanding forces of mach 7 or even more. This is proven in her fight against Kaede, when the latter had swung her around several times but Eruza was barely affected by this.
Fighting Style- Eruza is a speed-type fighter, one that relies on delivering as many blows as she can upon her opponent. When not fighting seriously, her feline instincts make her turn the fight into a game of cat & mice. However, when the situation gets serious she won't pull any punches. Although not as physically strong as her brother, she has been able to hold her ground for a while against a Destroyale veteran.
