In the silence of outer space, the sun of the Naruto World slowly rose along the curve of the planet's surface.
Exposed without any protection to countless forms of cosmic radiation, Josen held his breath in the vacuum and couldn't help spreading his arms to praise the sun.
After a moment, he realized that the omnipresent cosmic radiation hadn't hurt him, nor had the sunlight strengthened him like a certain Kryptonian. He immediately lost interest.
This trip to the Naruto World had yielded plenty. Not only had he saved Tobirama Senju, who had nearly died prematurely because of his arrival (Tobirama Senju: ??? Wouldn't everything have been fine if you hadn't come?), but he had also gained many of the elements needed to advance to the Six Paths level.
Most importantly, his motley assortment of abilities had been tempered by time and fused into a cohesive whole, bringing his combat power infinitely close to that of a childhood version of the god among men.
F-kid: Don't believe rumors, and don't spread them.
All in all, cause for celebration.
It was time to go back.
Dimensional Walk activated, and a portal with its own black-hole halo opened beside Josen.
Without hesitation, he stepped inside.
This time, there was none of the dizzying disorientation of crossing the Space-Time Gap. Breathable air suddenly filled his surroundings, and the familiar lake appeared before his eyes. He was back in the One-Punch Man World.
[Dimensional Walk has entered cooldown. Cooldown period: one month.]
"I'm back."
Everything around him was still as it had been after his encounter with Blast, while Josen, having completed a journey to another world, had undergone a transformation.
Then let's celebrate with some hot pot!
With a snap of his fingers, Josen vanished on the spot.
Ten minutes later.
