Seijuro was a man who had prepared for a lot of shit—Madara Uchiha being alive, aliens existing, all four nations forming an alliance.
For chakra to come from aliens. That the Gedō Mazō was the corpse of a beast. That Wood Style was something unique to Hashirama and not the Senju clan as a whole. Chapters first released on novel⦿fire.net
For reincarnation to be a thing—even for alternate realities to exist. For fuck's sake, he was able to deduce that alien's ability after just three moves. And the ability was hella complex. Unless revealed outright, most people wouldn't have figured that shit out.
He always saw himself as someone who stayed with one person at best. What kind of fucking shenanigans did his future self get up to, to end up with two?
Did Aizen go on his bullshittery again? Goddammit.
No... the alien said Seijuro, and by the point in the future the alien was speaking of, Aizen should've already been fused with him. Plus, it said Seijuro Kurama, not Aizen Sōsuke.
Speaking of which, the Aizen Sōsuke persona would be dying soon—roughly in like... twenty-ish years. Maybe ten.
Enough time to establish the Uzumaki as a world power.
He could supplement. And the Cloud was no longer a world power... He would be teaching the Uzumaki banned sealing methods—shit that could turn the Cloud or any other village into ash.
Seijuro had a plan: have his double make a copy of the Karma, though Seijuro would need some Ōtsutsuki for that. But it wasn't that big of a deal. He could give them like two or three Karma Seals, and then have them beat the shit out of any village that attacked.
Karma of who, you may ask?
Well... his. Give them his strength, without the drawback of him eventually taking over—since he would be fusing with Seijuro. And for those saying, "Well, he wasn't an Ōtsutsuki..."
Even if Seijuro was currently 100% human... that wouldn't stay the case for long. For fuck's sake, Mikoto was like 95% human, and 5% Ōtsutsuki—virtue of the cleansing bath Seijuro was giving her. She was returning a bit to Indra, who himself was 25% Ōtsutsuki.
She was making great progress, actually.
Anyway, speaking of the devil—
Mikoto looked away, cheeks pink but eyes sharpening.
Grinning. Full-on smug grin. Her hand even touched her belly for dramatic effect. "So I get to have Seijuro's babies, huh?~" she sang.
Seijuro's brain suffered catastrophic chakra burnout.
"WH—K-KUSHINA! We haven't even—don't say things like—" he was dying. Absolutely cooked.
Kushina tilted her head innocently. "What~? That alien guy said I'm the mother of one of your children. Must mean I'm wifey material, right?"
Mikoto's eye twitched.
Kushina noticed. "Ooooh, is Mikoto-chan jealous~?"
Mikoto tried to look indifferent. She failed miserably.
"I am not jealous of a walking tomato with anger issues."
"TOMATO?! I am not a tomato! At least I don't have pink eye."
Tsunade blinked. "...Damn."
Seijuro rubbed his temples. "God... dammit."
He turned to Tsunade for help.
She grinned. "Don't look at me, lover boy. You bagged two elite kunoichi. I'm honestly impressed. It seems like you inherited more from your father than you think."
"I'm not a player!" he groaned, audibly suffering.
"Oh? Then explain how both of them risked their lives for you," Tsunade hummed. "Willing to die for you. One even unlocked Mangekyō in the middle of battle to protect you. The other literally launched herself into a divine being's mouth to save you."
He tried to answer. Failed.
"It's either that, or you have a dick to die for," Tsunade teased.
Seijuro's cheeks flushed a deep shade of red.
"BWAHAHAHAHA!" she began laughing. Wow. She had found the perfect chance to tease this prodigy—why shouldn't she? It was like the perfect opportunity. Like come on, if you had the chance to annoy your friend knowing they couldn't do shit about it?
This was that chance. Everyone—yes, everyone—would take that chance.
Deciding to change the subject, his gaze landed on the Karma marking.
"When he died... he placed this on me," he said calmly, showing the Karma Seal.
Mikoto's Mangekyō looked at it.
It looked like a random black spot.
"Do you know what it is?" Tsunade asked, eyeing the boy.
"Let me see," Kushina said, taking his hand to inspect the mark.
Hm... it looked like a seal. A fairly complex one—she was barely able to understand it.
"Send some chakra to it," she said calmly.
Seijuro nodded before—
He sent some chakra through his Karma Seal.
As he did so... markings began appearing on his left arm, strange tattoos and all—and a horn began forming. A horn resembling the same one the beast had.
And as for Seijuro's chakra? It skyrocketed... skyrocketed past even what Kushina had. Even surpassing Kurama's chakra. Surpassing everyone's chakra combined.
"Oh... so it's one of those seals," Seijuro said calmly.
He could feel it. His body was changing... he was slowly becoming what Urashiki was.
An Ōtsutsuki. Without the drawback of Urashiki taking over and all.
He deactivated the seal.
"Why do you get a power buff for defeating an alien?" he sighed a bit, patting Kushina's head.
"Something's off with this seal."
