Context: Kamishiro Yuu 神代ユウ has gotten in a fight with delinquents, who are now searching for him. They find someone who knows him. Seeing this, Yuu says:
sono hito... Kaneda-kun wa mukankei nanda, onaji gakkou nadakede その人・・・金田君は無関係なんだ 同じ学校なだけで That person... Kaneda-kun has nothing to do with [this], [he]'s just from the same school [as me]. (dislocation.)
onaji gakkou na dake de mukankei nanda - he's just from the same school, and has nothing to do with our fight.
you ga aru no wa boku dake daro!!? 用があるのは僕だけだろ!!? The one [whom] {[you] have business with} is just me, [isn't it]? I'm the only one whom you have business with, am not I? It's me you want, isn't it?
