Kuroyukihime tells Chiyuri that she is dating Haru and drags him to a cafe. While there, Kuroyukihime explains her dilemma to Haru. Brain Burst was anonymously created seven years ago which allows acceleration only to those who were born with the neuro-linker. Therefore, all Burst Linkers are children age 15 and younger, allowing its existence to be concealed from the public. Kuroyukihime wants to meet the creator to learn the purpose of the program. To do that, she needs to reach level 10, which requires five wins over level 9 Burst Linkers and one defeat results in the permanent uninstallation of Brain Burst. Two years ago, Kuroyukihime was one of the Kings of Pure Color, a group of level 9 Burst Linkers that agreed to not fight each other, but she did not agree to the treaty and beheaded the Red King, causing her to be branded a traitor and leading her to seal away Black Lotus. Since then, she has stayed offline, only logging on to the school's local net with a dummy avatar. Recently, she was challenged to a duel by a Burst Linker named Cyan Pile, which could lead to her identity as Black Lotus being exposed. Thus, she must find Cyan Pile's identity. She suspects Chiyuri, which is why she provoked her, although Haru doubts it knowing that Chiyuri is bad at games. Haru begins the investigation by going to Chiyuri's home under the pretense of apologizing for lunch the other day. The two link up with each other with an extremely short cable and reconcile with each other, with Chiyuri letting Haru know that Takumu was not told about the bullying. During the conversation, Haru discovers that while Chiyuri is not Cyan Pile, there is a back door connection that could lead to finding its identity. (Source: Wikipedia)
