On Suzuki-san: That's the difference between a limbless anyone and a limbless Katou. Other people don't get power ups when losing limbs.
@ Nu-delic: On other teams "unique" members, certainly the possibility exists, but I don't think so. The Tokyo team doesn't have much to show, aside from the main character (which only applies to us readers), other than the vampires and the espers. I think it's part of the reason the team is "special" in a way.
@ Etufo: I'm with you on the boss being responsible for the biker's death. It doesn't seem like a melee attack, so maybe the boss has invisible projectile attacks like Nuri. However, I think Cherry will still put up a fight of some sort. I guess he'll finally have his ass handed to him - aside from sakata's loss, he suffered no real blow back there - but we'll remain alive.
