Chapter 220: Fusion of Yin–Yang Release
After thoroughly mocking that so-called "evil old Senju ghost" who caused him to get scolded every other day, Gen flickered and reappeared back home.
A lot had happened recently, but to him, it wasn't anything out of the ordinary.
"The shinobi world has always been chaotic. What's a little more chaos on top of that?"
At first, he thought he was just tossing words out casually. But once he was home and reflected on it carefully…
He suddenly realized—
It actually made a lot of sense!
"Phew…"
He let out a cold breath. If you didn't know the whole truth, just reading the Uchiha stone tablet alone would definitely give you the impression—
"The Sage of Six Paths really did favor Indra, no wonder Ashura was dissatisfied!"
rubbed his jaw, feeling a little uneasy. Did he just slander Ashura by accident?
Well… considering he was on the moon, quietly throwing shade at the Sage of Six Paths without anyone stopping him—he figured it wasn't much of a problem.
"Anyway, blame it on his sons. No big deal."
Nodding seriously to himself, he put the matter aside.
What truly piqued his curiosity now was the "gift of nature" he had received from Nagato.
"Both the Tenseigan and Rinnegan are collections of creation and destruction… but the way each understands and wields that power is very different."
And from those differences came entirely different results.
By observing from different angles and insights, he could expand his perspective—and most importantly, better integrate Yin Release and Yang Release into one.
"These past three years on the moon, I've gained a deep understanding of both Yin and Yang Release, and I've even made some refinements in their application. Now, all that remains is the final step: fusion."
It was the last step—yet the most troublesome one.
Still, he wasn't worried about time. With his Ōtsutsuki potential, patience was on his side.
After all, while not all of the Ōtsutsuki wielded kekkei mōra, when it came to Yin–Yang Release, they were all masters.
Especially as his bloodline continued to evolve, he could feel his grasp of Yin–Yang Release slowly improving.
"But I'm not the kind to just sit and wait. Rather than letting my bloodline drive the process, I'd rather actively fuse them and use that to push my bloodline even further!"
With that thought, he opened the system's reward.
In an instant, that familiar sensation struck again—like his brain was itching, on the verge of sprouting a whole new one.
Fortunately, he was long used to this strange feeling. He immediately began analyzing and absorbing the new knowledge flooding his mind.
"Hah… so it really does differ from my Tenseigan's methods. Even the way Yin–Yang Release is applied feels distinct—or maybe it's different right from the point of origin."
When the influx of knowledge finally settled, he couldn't help stroking his chin thoughtfully.
The Rinnegan he possessed had been awakened by Uchiha Madara in his final years. Madara's method involved using Hashirama Senju's cells, thereby gaining the "Power of All Creation."
Under such immense power, Gen had managed to cleverly construct the effect of "Yin–Yang Unity."
From it emerged unique techniques—and unique results.
"Like those black receivers… and the Outer Path: Samsara of Heavenly Life?"
He speculated silently. At least, his Tenseigan never granted him those abilities.
The black rods he wielded were entirely his own creation. While they worked fine in battle, they always lacked stability.
As for the Samsara of Heavenly Life Technique…
He had never "rolled that prize out of the box."
Not that he cared much—after all, he had his own Rebirth by Self-Sacrifice. Still, the difference was undeniable.
"This pair of Rinnegan also lacks the high-explosive power of techniques like the Silver Wheel or Golden Wheel Reincarnation Explosions… and doesn't have a chakra mode either."
Of course, that didn't mean the Rinnegan had no unique jutsu.
Techniques like Amenotejikara and Limbo: Border Jail were certainly special—but the disparities between each eye's abilities were striking.
"It really comes down to mechanisms versus raw numbers…"
Gen sighed, then realized something important.
"These are Madara Uchiha's Rinnegan. And no two pairs of Rinnegan are ever truly the same."
In his memory, Urashiki's Rinnegan was the most peculiar—an eye shifting between blue and red, tied to space-time manipulation.
But his offensive power was terrible. That only confirmed the Rinnegan's defining trait: its unique mechanics.
"Different Rinnegan follow different mechanisms, leading to entirely different interpretations and applications!"
The thought made Gen's eyes light up.
The Tenseigan was rare, but among the Ōtsutsuki, Rinnegan were practically everywhere. Other than Isshiki, it seemed like everyone had a pair.
"Even though I'm developing my own Rinnegan… we're all Ōtsutsuki here. If my eyesight's bad, doesn't that make it my Rinnegan too? Try arguing with my Golden Wheel Reincarnation Explosion!"
In his mind, those Ōtsutsuki who fled were traitors; those who didn't flee were just well-trained traitors.
"As long as you're living desperately, I'll be firing desperately."
He shook his head, exhaling deeply.
"Forget it. For now, I'll just focus on fusing my Yin–Yang Release. Only with overwhelming strength can I truly deal with them."

Meanwhile, at the Senju clan's ancestral home, Hashirama, Tobirama, and Tsunade sat in uneasy silence.
That stone tablet had stirred far too many problems.
"Brothers? We're actually related to the Uchiha?"
Tobirama paced back and forth, fuming.
"Damn it! How could we possibly share blood with those cursed Uchiha?!"
"What's so bad about it? I think it's kind of nice," Hashirama blinked, oddly cheerful.
"No wonder, when I first saw Madara by the river, I felt so close to him—like family."
"Brother! How can you smile at a time like this?" Tobirama clutched his head in frustration.
"Don't forget—he betrayed Konoha! You killed him with your own hands!"
"You're the one who said maybe he didn't actually die."
"…Why do you only remember that? What about our clan's relics? You should be remembering those!"
"I really don't know. Father never told me—if he did, it was to you."
"Unbelievable… do you dump everything on me?!"
Having such an elder brother was pure torment. Tsunade finally broke in.
"Instead of bickering, shouldn't we be thinking about this 'new plan' of the Sage of Six Paths? What do you think it means?"
"How should I know? A being like that is beyond comprehension," Tobirama muttered, shaking his head.
But Hashirama frowned.
"Could it be connected to Madara's departure?"
"…What?"
His words stunned Tobirama. After a long silence, he shook his head.
"I don't know. But if it is, then it's the worst possible outcome. Don't forget what he did afterward."
Hashirama opened his mouth, but no words came.
After all, Madara hadn't been gone long before returning with the Nine-Tails, leading to their earth-shattering battle.
If that was truly tied to the stone tablet… the implications were dire.
"There has to be a reason," Hashirama whispered.
But before he could continue, Tsunade stepped in.
"There will be answers. If you're right, Sasuke will eventually see those truths—and with Gen around, I doubt it'll spiral out of control."
"I only worry Sasuke might walk the same wrong path as Madara," Tobirama said. Yet, even he had to admit—Gen was capable.
"Forget it. Like Tsunade said, with him around, it won't be a problem. He's not only stronger than you were, big brother, but also tougher, sharper—and far less… good-natured."
"…Not much of a good person at all," Hashirama muttered under his breath.
"What was that?"
"You misheard me. Anyway, do you think Gen was right?"
Tobirama snapped, "Right? It's all nonsense! Even if I have to dig three feet through the earth, I'll prove it false!"
"But we don't remember any relics of the Sage of Six Paths…"
"Then we'll dig until we find them!" Tobirama barked. He stood abruptly, glaring at both his brother and Tsunade.
"Tonight, you two will search. If you can't find anything, then go to our old clan grounds and dig there! No matter what—it must be uncovered!"
"…Ugh."
Tsunade and Hashirama exchanged a look of mutual suffering. Finally, Hashirama asked weakly,
"And if we still don't find anything? What will you do then?"
"If there's nothing, then that's proof enough!" Tobirama's expression was grim.
"In that case, I'll scour our clan's archives myself. I refuse to let that brat Gen's words become prophecy! For the sake of our clan's honor, I'll risk everything!"

The next morning.
Kitagawa Gen slowly opened his eyes, excitement flickering within them.
"So it really works… the fusion efficiency is this high?"
He had spent the entire night focusing on merging Yin and Yang Release.
Unlike the fusion of bloodline limits, this was the unity of body and spirit itself.
Its difficulty was leagues above anything he had attempted before.
Even with his Ōtsutsuki heritage, the process had been painfully slow—until now.
But this time, he had found the breakthrough point. The fusion was accelerating rapidly.
"At this rate… in about a month, I should see results."
A month. Neither long nor short—but after all his years of waiting, it felt like nothing.
What intrigued him most now was how much further his bloodline would evolve once Yin–Yang Release was fully integrated.
"In the early stages, the growth will be massive. But at this level… it's hard to say."
He stroked his chin thoughtfully—until a faint sound reached him from the windowsill.
Raising a brow, he soon smiled.
"Figures."
He walked over and gently opened the window.
Sunlight poured in, illuminating a row of vibrant flowers in full bloom. Though hardy and ordinary plants, their blossoms were beautiful, filling the air with freshness.
Beyond them, a familiar silhouette stood waiting.
Gen's smile widened.
"Morning, Ino."
"Good morning, senpai."
