if you are wondering what happened to Neji after the delta arc.. the war happened and the events that happened are the same including Neji's Death..
once you reach the naruto: the last arc, it claims tsukasa has a katana and yes he does, he used it once or twice in the previous arcs but for that arc itself tsukasa doesn't use it at all.
