Why did kishimoto decide to end naruto?������
Look as i said in other topic, TV company can decide to make gaiden series like with Dragon Ball GT was done, but Toriyama didn't created GT after all so ssj4 don't excist at all.
Same can go for gaiden if rating gonna be blast they can think about it and make seperate team who will creat new series and story. But who knows maybe it's over for good.
Plus naruto had more fillers than any other manga lel even dragon ball/Z had no fillers lel![]()
