The Jellyfish Sage was a formidable opponent. From their few short seconds of battle enough data was compiled on Heihachi. Seijuro accounted for the fact that Heihachi might take it a little over the top if he deemed Seijuro too hostile, which seemed to be the case. The water began to pull back toward a single side of the warehouse, reminiscent of the tide before a tsunami. There was one problem with Heihachi's attack... where was his target? Seijuro had no form after activating his Hiding in Camouflage technique which even erased his chakra presence, so what did the legendary Sage have to track Seijuro with? 

As the tsunami crashed it would have no single point to converge on as there was no way of knowing where Seijuro was, and so the large wave would surge throughout the entire warehouse. Knowing this Seijuro used the time he was given as the giant tsunami formed to backflip onto the walls of the warehouse, his feet planted with chakra. The wave came down and the warehouse burst at the seams, sending streams of water throughout the southern end of Konoha. The walls fell to the ground, Seijuro making himself visible as he rode the top of the wave on his feet, landing outside of the warehouse. 

He turned to look at Heihachi with a grin on his face. "Impressive. I needed to know you were still in fighting form before I spoke of my true intentions. But alas we have lost our privacy thanks to our engagement. Please, follow me once more. We have little time before tonight's events are to unfold as I'm sure you know of, rebel." Seijuro disappeared from sight again to remain hidden from the shinobi of Konoha. Knowledge of his existence was on a need to know basis and none of the commoners needed to know he was even alive. This time, however, Seijuro did not conceal his chakra as Heihachi needed a way to follow him. 

Seijuro darted off through another alleyway to escape the fallout of their encounter.
