Six Paths Susanoo: Defense of the World

All three siblings manifest their Perfect Susanoo infused with Six Paths Sage chakra and Senrigan chakra and expand it to cover the world. The Susanoo is triple-layered for each sibling but is stretched thin. Hitting the same spot over and over will break through and create a hole in the Susanoo.

Drawbacks
Major drawbacks of this defense is that the barrier is thin. Another is the massive amounts of chakra used to create the gargantuan Susanoo. Another would be the the triplets aren't defended themselves. Attacking one of the siblings would break their concentration and the Susanoo will collapse.
