And then, suddenly, Kiba saw nothing. Absolutely nothing. Just blank white space everywhere. The entire universe was a minuscule bit of nothing somewhere out of site.

He didn't care though - he had his size. His wonderful, wonderful size. Every fiber of his being felt absolutely amazing.
Since there wasn't much reason to have them anymore, he stripped away his clothing - as soon as he did so, the clothing stopped growing with him, and within moments it was gone as he outgrew it all. Now a nude giga-giant, Kiba took notice that the growth seemed to have buffed him up quite a lot! He flexed one of his biceps and was pleased at the big peak that formed. He flexed his other muscles, admiring his own physique one group at a time. Then he layed back in the nothingness, putting his hands under his head. This was the life. Nothing to do but grow and grow and grow.

But then... it was odd... the white space around him tinted tan, and was getting tanner, like skin. Was he... catching up to somebody EVEN BIGGER?!
Indeed, within a few moments he was face-to-face with a huge toe. Then toes. Then a foot. Then feet. Then a very very muscular set of legs. A wall of 8-pack abs. And finally, one extremely pumped up muscle-ninja.

"Yo, guys, we finally got another one!" the ninja said, smiling. There seemed to be several other ninjas at this gargantuan size, each one with the bod of a pro bodybuilder, and then some! Seems that over time this growth really packs on the beef.

"Welcome to the Realm of Eternal Growth, bro."
