Saki follows up on Takao's clue from the previous episode, and tries to find out as much as she can about the mysterious rock star named Xeku. But information about this engimatic figure is hard to come by. His concerts are never advertised, but his fans always seem to find them. Cassettes of his songs are sold on the street like shady black market goods, unavailable in any record store. Even Nishiwaki can't be of much help, but Saki hits the jackpot when she finds Xeku's biggest fan, a girl named Yuko... By the way, Xeku's song from the middle of the episode: it's called "Night Walker" by Nagashima Naoto (ナイトウォーカー by 長島ナオト). I wasn't able to find the Japanese lyrics on J-Google, but if any of you know where they are available, I'll get them translated and include them in a version two release.
