Unlike the latter of Hell Seether, she's the one who committed the most betrayal and losses to others. Even during her time at the Blackstorm racing event two years ago, she sacrificed her own teammates to gain an advantage in racing.
And even though that day has passed, she never gets over her foulness to gain what she seeks. And that is pride. A pride of Hell Seether to get what they want by any means.
And despite her foulness being scorned by the latter, Tokino treated her like a special child like Ciel did, but with the first child's treatment. Every time she causes trouble, Tokino will have a field trip to correct her.
PS: I changed her clothes' colors and a hairstyle.
