Me and a friend disagree on how strong susanoo is. He thinks rasenshuriken can break it but I disagreed with him. I don't think it would happen. I wanted to see wha NB thought
when he Negated RS with rinnegan he HAD to : he was drawn out of his Susanoo by Gaara's sand , and Forming a new susanoo would take time That's why he chose RinneganMadara chose to use Rinnegan to negate Rasenshuriken, not his Susanoo which he could easily have used. Madara recognised the power of the technique and chose his only option for defence and it wasn't Susanoo'.
lol xdYour friend deserves a B-slap if he thinks rasen shuriken can break through Susanoo.
