When Haruyuki first meets Yuniko, she has a personality of that of a normal girl. She was sweet and caring to Haru. She presented good manners such as greeting him and was shown to be able to cook well. However, after Haruyuki discovered Yuniko's identity and that she was the current Red King, her personality changed radically, showing her true colors. She is rude and gets frustrated easily when things don't go her way. Yuniko has a rivalry between Kuroyukihime, and the two get on each other's nerves, but they also care for each other more than they let on. In spite of her polite personality being a facade, Yuniko is also somewhat kinder than she realizes. While she claims that bonds between Burst Linkers are meaningless, Kuroyukihime points out that Yuniko still wants to believe in the "ultimate bond" between a "parent" and "child", which is why she hesitates to use Judgment Blow on Chrome Disaster. She also will sometimes help out Haruyuki and the others while claiming that it's only repaying a debt or for her own legion's interests. In battle, Yuniko appeared to be sadistic, enjoying to see her enemies being destroyed by her full barrage of heavy weapons.

But his life takes a drastic turn one day, when he finds that all his high scores have been topped by Kuroyukihime, the popular vice president of the student council. She then invites him to the student lounge and introduces him to "Brain Burst," a program which allows the users to accelerate their brain waves to the point where time seems to stop.

However, if a user loses all their points, they will also lose access to Brain Burst forever. Kuroyukihime explains that she chose to show Haruyuki the program because she needs his help. She wants to meet the creator of Brain Burst and uncover the reason of why it was created, but that's easier said than done; to do so, she must defeat the "Six Kings of Pure Color," powerful faction leaders within the game, and reach level 10, the highest level attainable. After the girl helps Haruyuki overcome the bullies that torment him, he vows to help her realize her goal, and so begins the duo's fight to reach the top. [Written by MAL Rewrite]
