The Ōtsutsuki were a divine race. They could survive without eating; any food they consumed would be completely absorbed as nutrients. They had no assholes, had no need to fart, and certainly had no need to shit...
But they still needed to breathe... Compared to humans, who depended on oxygen from the outside world, they were more advanced. In a vacuum, they could use Chakra to create oxygen. It was a little-known talent of theirs.
The foul air here made Ryushiki uncomfortable, so he desperately wanted to create fresh oxygen.
"Ohh~" Tobi offered a "kind" reminder. "I'd advise you not to do that. The methane filling this place is flammable. The reason the flames of Amaterasu on your body haven't ignited it is because there's no oxygen to support combustion. If you create oxygen, it'll explode instantly, and shit soup will splatter everywhere..."
"I know that without you telling me!" Ryushiki coldly emphasized as he held his breath.
Tobi set the pace. "Then let's begin. The rules are simple: free-for-all combat, but Space-Time Dimension techniques are forbidden!"
"That's not for you to decide!"
Ryushiki narrowed his eyes.
—Yomotsu Hirasaka!
Splash!
But... all kinds of filth poured out from the opened Yomotsu Hirasaka!
Ryushiki stepped back to evade it, then grimly shut Yomotsu Hirasaka.
Tobi said, "I forgot to tell you. Like Kaguya's Amenominaka, this is a composite space. The surrounding dimensions are all filled with filth and grime. Trying to escape is useless."
Killing intent surged in Ryushiki's eyes. "Then I'll kill you here first, and find a way out afterward!"
"Right, that look... Let's start our game. But let's be clear—I'm not that easy to kill!"
Whoosh!
Tobi vanished into the void, becoming one with this "Shit-Ball Dimension"!
After all, this place contained six hundred million tons of shit.
