See, in the first episode, as detailed as it was, you don't get enough information. Okay, this sixth grader is practically going phsyco from losing his title. And the only one he has to bully is pig boy, Of whom Uichii thinks is the one who started this. (In the classroom scene, with everyone's cell phones, go get the idea that either pig boy is behind all this or he's trying to defen Uichii.) (Although the way pig boy talked kinda disturbed me, it sounded like he was lying. Either that, or a bad voice actor.) With only seeing Lil Slugger twice in the whole show, you know it's not Uichii or pig boy, but it could be anybody. (They had a piece about this in Newtype Magazine that might help.)
