"Hahahaha—!"
Seitian's laughter rang out across the empty plaza, sharp and cold, bouncing off lunar stone like metal on metal.
Above them, the Giant Tenseigan floated like a second moon—an eye too huge to feel natural, too alive to be called a tool.
Since Ren arrived, Seitian had been forced to swallow humiliation after humiliation.
But now?
Now he finally had something that felt like certainty.
He glanced down at Toneri's limp body, laid him carefully on the ground, and straightened.
"Toneri… I'll avenge you."
Then he lifted his head, voice turning vicious.
"After I crush you, Fifth Hokage… I'll take him to Earth."
He smiled like the future was already decided.
"And I'll wipe Konoha off the map."
Ren's expression didn't change.
Only his eyes cooled.
"You want to massacre Konoha…"
He took one step forward.
"…did you ask my permission?"
The air tightened.
Ren's presence expanded again—silent, invisible, but undeniable.
BOOM.
The shockwave didn't just push outward—this time it felt like it pressed down.
The lunar ground trembled in a faint, ugly ripple.
Even the distant cliffs seemed to vibrate.
Seitian's pupils constricted.
It's stronger than before…
For a breath, something like instinctive fear surfaced.
Then his gaze flicked up to the Giant Tenseigan—his anchor, his pride, his "answer."
And the fear hardened into arrogance.
Ren was terrifying.
In the shinobi world, he was a walking disaster.
But this was the Moon.
And that eye… belonged to his bloodline.
"Die."
Seitian's chakra flared—strange, pure, carrying the ancient signature of his clan.
The Giant Tenseigan responded instantly.
No warning.
No buildup.
It simply activated.
A surge of green energy poured down like a curtain and swallowed Ren whole.
Ren's brows pulled together.
Not from pain.
From recognition.
The green flow wasn't just pressure—
It was stealing.
He could feel it: his chakra being pulled outward, drained by a force that didn't ask, didn't negotiate.
He shifted his stance, about to counter with his Sage Body chakra—
When a familiar, cold voice sounded in his head.
[System Notification]
Ding! The host has triggered the Giant Tenseigan. Hidden conditions for the Moon sign-in have been met.
Proceed with Moon sign-in?
Ren's eyes narrowed slightly.
Now?
No hesitation.
"Sign in. Now."
One second.
Ten.
Thirty.
The green energy continued to claw at him, trying to peel chakra away layer by layer—
And then the system's tone rang out again, crisp and final.
Ding… Moon sign-in successful.
Ding… Reward acquired: "No-Damage Giant Tenseigan Absorption Trial Card" ×1.
Ding… Reward stored. Can be used at any time. Upon activation, the Host can safely absorb the Giant Tenseigan's energy and break the Six Paths restriction.
Ren's heartbeat didn't speed up.
But something in his eyes sharpened—like a blade finding its edge.
…A trial card that lets me absorb it safely.
He'd been thinking about how to tear power from the Giant Tenseigan without his own body collapsing.
How to force a path into Six Paths when the world itself suppressed it.
And the answer had dropped into his hand at the exact moment the Giant Tenseigan tried to execute him.
Ren's mouth curved faintly.
Not a smile.
A decision.
Seitian watched Ren swallowed in green light and sneered, voice thick with triumph.
"Idiot."
"You're not Ōtsutsuki."
"You don't have our bloodline, and you dared stand this close to the Giant Tenseigan?"
He spread his arms as if announcing judgment.
"Your death is guaranteed."
Ren's voice came from within the green flood—calm, almost bored.
"Is that what you think?"
The green curtain flickered.
Ren stepped forward, still wrapped in the draining force, and looked Seitian directly in the eyes.
"Seitian."
"That Giant Tenseigan…"
He paused—then spoke like he was taking possession of something that already belonged to him.
"…I'll be taking it."
Seitian's face twitched.
"What…?"
And then—
something happened that shattered his confidence in a single breath.
The Giant Tenseigan… stuttered.
Not physically—spiritually, like a machine that had lost its master command.
The draining force that had been pulling chakra out of Ren's body suddenly reversed.
Hard.
Violently.
Like a river snapping backward.
WHOOM—!
A tidal surge of energy poured out of the Giant Tenseigan—
and rushed into Ren.
Not trickling.
Not leaking.
Flooding.
As if the eye had become a reservoir with a broken dam… and Ren was the only path left for its power to escape.
Seitian froze.
His brain couldn't process it fast enough.
The Giant Tenseigan—his trump card—was feeding Ren.
"No…!"
He threw his chakra into it, trying to seize control through his bloodline.
Trying to reassert the command that should've been absolute.
Nothing.
It didn't listen.
It didn't respond.
The Giant Tenseigan ignored him like he was a stranger.
Seitian's face went pale.
For the first time since Ren arrived, his voice cracked.
"How is this possible?!"
Ren didn't answer.
He didn't need to.
Because the change was visible.
The energy entering his body didn't scatter or explode—it settled, then compressed, then restructured as if it had finally found the correct container.
Inside Ren, five forces collided—then began to interlock with terrifying inevitability:
Sage Mode's refined senjutsu chakra
The Giant Tenseigan's lunar eye energy
Armament Haki's dense black power
The Eternal Mangekyō's ocular force
The awakened tremor-force, vibrating as if reality itself was a surface to break
The fusion wasn't gentle.
The air around Ren began to hum.
Not a loud sound—
a low, constant vibration that made the plaza stones tremble and dust rise in thin streams.
Ren's presence grew heavier by the second, like a star gaining mass.
Seitian's instincts screamed.
His legs tensed to retreat—
but his pride wouldn't let him move.
So he stood there, watching his "secret weapon" dim as it emptied into Ren.
And the more it emptied—
the more Ren felt like something the world could no longer suppress.
Seitian's throat tightened.
He forced words out, half threat, half panic.
"You'll die! You'll burst—!"
"It's ours! The Ōtsutsuki ancestors won't forgive you!"
Then his voice dropped, almost pleading, hatred twisting into helplessness.
"Stop… stop absorbing it—!"
But the Giant Tenseigan didn't stop.
It kept pouring.
And Ren didn't slow.
He looked up at the eye like he was evaluating a resource.
Like this was not a holy relic—
but fuel.
Seitian's hands shook.
His lips went numb.
His eyes went wide with the kind of fear that doesn't come from being outmatched—
but from realizing you just handed your enemy the exact key they needed.
"This… can't be…"
Ren's gaze lowered back to him.
Cold.
Certain.
And for the first time, the Moon itself felt small.
