Whip is a clone of the real Seirah, K Dash's biological sister, who was kidnapped by NESTS and died under unknown circumstances.
She retained the original's feelings for K' and continues to be very warm towards him, trying to motivate him.
Whip spent some time on the battlefield as a mercenary and then decided to enter fighter tournaments to get more information about NESTS.
Whip is always surrounded by an enigmatic aura due to her quiet nature and unwillingness to share her plans. However, she consistently achieves her goals and appreciates her teammates.
Whip's fighting technique is based on the Japanese art of Soubenjutsu. She also borrows many techniques from other styles, mixing them with firearms. The whip she wields can also change shape and transform into a knife or gun.
Seirah is always dressed in a strict uniform, which at the same time is comfortable enough for combat. She never parted with her whip.
