Dammit Koyuki, do NOT get yourself involved with another girl.
And I laughed when I found out that Saku and Koyuki ended up at the same school as Chiba. At first, I thought they were aiming for the same place as Maho, but then I remembered that she doesn't go to school in the first place, as far as I know.
Actually, what does she do concerning education? Does her rich-yet-unseen father pay for private tutoring, since she doesn't know Kanji? It would make sense.
And I'm interested to know the secret behind Lucille and Beck now. I reckon that Beck was run over and was fixed up by vet Black Jack, aaaand Lucille... I'm gonna guess a Syd Barrett type thing.
For those of you who don't know Pink Floyd, Syd Barrett was the original guitarist for Pink Floyd, but he went insane. Seriously. They'd be on stage and he'd be playing to one song while everyone else was playing another, and so on. Eventually they kicked him out of the band and replaced him with a new guy, but Syd kept turning up at concerts demanding to get on stage with his band. It got so bad that he was eventually sanctioned.
Anyways, I reckon that back in the Serial Mama days, Eddie and Ryuusuke kicked out one band member who then decided to shoot Eddie's guitar, and now wants to finish the job.
Mind you, it could also be Erika's ex-boyfriend that hates Eddie. Who knows?
