Kuroyukihime was formerly the Black King, although she was driven into hiding after beheading the first Red King, Red Rider, while trying to defeat the other kings to reach level 10. She values Haru as more than a subordinate and is often the voice of reason to him when he is willing to go to extremes to protect her. Prior to her hospitalization, she confesses to Haru that she fell in love with him.

There is nothing known about her abilities of her virtual character, or her brain burst character. What is only known is that her virtual character defeated Haruyuki’s high score in a squash game. It is also known that her brain burst avatar, the “Black Lotus” is a powerful avatar, since she was able to defeat the previous Red King. Outside of her knowledge of the brain burst program and her virtual network knowledge, she has been shown to be a great strategist.

Her real first name is partially revealed at the end of episode 24 when Fuuko Kurasaki calls her “Sacchan”.
