Sabu's plan seemed to have failed. But that was fine! Instead of making knives with chakra that was just absorbed, Sabu resorted to using the water he still controlled in Ryoji's eyes to crush them like grapes with sheer physical force. Specifically, with his pressurizing ability, he was able to put his opponent's eyes under greater pressure then they would have ever felt, and since Sabu could pressurize water nearly infinitely, no moniker would save Ryoji's eyes. It was also far too late at this point to use any of his eye's tricks, as the water would just absorb that chakra as it came out of the eyes since we're playing this horrendously lame absorption game. After it had edited out his eyes, the water would try and enter further into Ryoji. Moving his watery body without chakra was just one of the many things that made Sabu the best, which he was. This battle was quickly turning into an arrogance-fest behind the fourth wall, among other things, and despite Sabu knowing that he just couldn't stop.
Now, with that done (just before Ryoji jumped away) and his enemy making seals, Sabu would return all the water in the air to his body at the speed of hydrogen bonding, not even because he sensed the technique or because he knew what it was if Ryoji started it, just because it was an obvious opening. Unbeknownst to Sabu, his simple logic that any good fighter would have just saved his life. "Common mashed potato-eyes, do something!" Sabu said before Hirashin-ing back to the kunai which had fell at the edge of closing the barrier to make his move, and coincidentally far from the death god. Sabu would have been honored to know the Shinigami was a fan, but not surprised. Like I was saying, the barrier was pretty small now considering this was the fifth post since it started and it only took seven to close. Although, unbeknownst to Sabu, this might not still be an advantage anymore.
Sabu, still all Sagely, drank his Hero Water to increase his chakra tenfold and used that chakra to alter his body to beyond inhuman levels. His muscles were bigger, faster, and more powerful than any man who had ever lived, as converting water to chakra and vice-versa was simple, Sabu turned into a bit of a hulking freak in an instant with his superhuman condition enhancing him to the level of a master. Blind old Ryoji would have surely sensed this, as the ground would be crushed into a crater under this newly-made thing. He was less human and more water golem now. But none of it mattered as he coated his body in Kenton and vanished, making the crater twice as big from his departure from that spot. Upon closer inspection, it would show the crater had two slashes in it that were over 10 feet deep. The sage mode and insane amount of chakra released and focused into the sword-body armor allowed Sabu's Kenton to reach exactly that far from his body, and he would just try and slice right through Ryoji and his clone.
"Hah!" Ryoji said confidently as he read that. "Now I can just absorb him! Like I've been doing this whole time! Truly I am a genius." But wait, dear readeryoji, and continue. It has been noted that fast enough users can cut chakra absorption techniques before they take effect to break them, but usually this took speeds impossible for man to reach, even with the Lightning Release Armor. But now Sabu our hero and Sabu our lord and savior (he made me write that) was far, far beyond that limit. He could cut anything, and the Shinigami was a thing, so he wouldn't be stopped by it reaching out to diddle his piddle and "seal his soul in hell" or whatever. Realistically, with his form and buffs allowing him to reach speeds around the hypersonic level, the death god himself would probably miss if he'd be trying to reach Sabu where he was, not where he was going. That was likely, as Sabu left an after-image that someone might be able to catch a glimpse of. Maybe the death god had sharingan! Well it wouldn't have helped him react in time. Maybe if Ryoji had a pair too! But alas, they were crushed grapes because he made no effort to deal with the water that had clearly invaded his eyes. He couldn't absorb the physical water like it was chakra, unless Sabu had converted it as such for him. Oh well, no Inanazazanagi-gi or Amaterasmisu or Susannano'o or whatever would save him from Super-Sabu at this point. Unless he could alter his physical makeup like Sabu could, Ryoji would never be able to keep up.
Seriously this fight has been pretty fun for me at least and Ryoji and I have been friendly to each other throughout it behind closed doors so don't read this and think of either of us as dicks. Well, you can, but know it's dickishness in good fun. I hope.
