Intro. \Hikaru is a hacker (but the good guy) who usually competes in a company against other hackers to see who is better, he also usually competes in motorcycle competitions, which makes him very famous and fans and some people have him as nickname "King cobra" (like snakes, because of his way of driving on the motorcycle and how he manages to hack easily).
In one of these motorcycle competitions, he meets Yio Kan, someone who handled the motorcycle much better than him and who stole the attention of the entire audience in the competition for his driving and his movements, also Kan is a hacker, but this is something that no one knew until he was interviewed after the motorcycle competition, Kan won the motorcycle competition, and for the first time it wasn't Hikaru who won.
This for Hikaru made him very jealous of all the attention that Kan was stealing, so he decided to approach Kan after the interviewees finished interviewing him, to tell him to make a bet...\
