Konoha – Senju Residence
Anyway, while the rest of the world was currently in shambles, he was currently playing a game with Kushina—it was about seals.
He looked at the seal she crafted. It wasn't overly complex, yet at the same time, quite complex.
So the seal had... the fire insignia, then some air seals, a spin seal, a release seal.
A 5-second timer seal, some buildup, alongside other stuff.
He furrowed his brow a bit.
"You will not get this one. I spent a long time on it, dattebane." Hm. Wasn't she quite talkative now?
"It's a fire release seal," he muttered calmly, looking over the details once more.
"Using the fire seal, a fire is created. In order to maintain it as it flows out, the wind seal is used to provide some oxygen. The spin seal is used so that when the fire is released from the scroll, it comes out in a spinning motion—a drill-like fashion, one might say."
He would ponder for a bit.
"The fire would be ranked as B-rank, and would continue coming out of the seal as long as there is chakra. The seal siphons chakra from the user, with the help of the siphoning seals."
He said this while looking at the full design of her creation.
"Took you long enough," she would say. Her gaze then landed on his seal.
She lightly gazed at it before opening her mouth and saying:
"It's a barrier seal. It seals off someone from the outside world before imposing a big gravitational push on someone in all directions, up to 100x Earth gravity. It then summons thousands of cuts from wind-style jutsu and cuts the target repeatedly—cutting at the nerves and so on."
Heh. She was able to figure it out so easily. Good to know.
"It's a new seal I've been working on. However, I've been unable to recreate the seal."
Kushina would look at it.
"You're using the Four Symbol Seal as a baseline to create your barriers and trying to incorporate that while also being able to use your kekkei genkai, imbuing it within the barrier—basically creating your own domain..."
"You are surprisingly clever..."
"What's that supposed to mean?" Kushina would say, looking at him with a glare. Was she being called dumb? She wasn't dumb—she was smart. Incredibly so.
She would pout... cute.
"I was simply implying that you are quite perceptive when it comes to seals," he said, rephrasing his sentence to sound a bit nicer.
She seemed to take the bait, seemingly proud of herself.
"If it's seal-related, I will be able to figure it out. After all, I am Kushina Uzumaki." She had a bright smile on her face—how sweet.
She was proud of herself. Oh well, that was good for her.
"If it isn't a bother to ask, can you help me with this?" he said politely. Her eyes seemed to brighten at the chance, and of course, she agreed. Even when he said it would be difficult, she didn't mind.
Oh well, good for her. Anyway, his technique he was working on was a variation of the one he got a while back—but instead of forcing someone into that box and slashing them over and over again...
Instead, once inside the box, they would be inside his domain. The seal would work to boost his technique effectiveness by 120% all the way up to 500% effectiveness. All in all, it was meant to be quite busted.
TL;DR—once caught in his domain, no one would be able to escape its range. He was planning to use the Flying Thunder God jutsu in this.
Teleporting them into the void somewhere, making sure that once trapped inside the domain, you cannot brute-force your way out. The only way to be freed would be for Seijuro to run out of chakra or for someone in the outside world to shatter his barriers from the outside.
Though while inside the barrier, his techniques would basically be sure hits.
Basically, it should look :
🌀 Fuinjutsu: Yūgen Kuyō no Jōheki (Not final name)
(封印術・幽玄供養の城壁 – "Sealing Art: Fortress of Subtle Oblivion")
Classification: Space-Time Ninjutsu, Fuinjutsu, Barrier Ninjutsu
Originator: Kurama Seijuro Thᴇ link to the origɪn of this information rᴇsts ɪn novel fire.net
Base Foundation: Flying Thunder God (Hiraishin no Jutsu) + Custom Sealing Arrays
🧾 Technique Description:
This technique functions as a personal domain.
Upon activation, Seijuro creates a specialized barrier seal across several pre-marked Flying Thunder God formula points, forming an instantaneous dimensional shift. All targets within range are forcibly teleported into an alternate space—a void-like sealed realm—completely separated from the material world.
🔒 Structure & Function:
Entry Trigger: Activation of Flying Thunder God marks configured into a complex three-layered barrier seal. Can be embedded into kunai, terrain, or latent marks on the opponent.
Teleportation: Instantly relocates all entities within the seal's radius (10 to 30 meters) into a stabilized inner realm.
Realm Type: Isolated space-time pocket dimension. Terrain is void-black with floating platforms of seal-scripted stone, maintaining anchor points for Seijuro's jutsu to bounce between.
Barrier Anchors: Exists via a four-pillar fuinjutsu barrier tethered to the real world. These external anchors must remain intact to sustain the realm.
Destroying one will destabilize the domain.
Destroying all four releases all trapped entities instantly.
🔁 Rules Inside the Domain:
Chakra Efficiency Buff:
All of Seijuro's ninjutsu, bukijutsu, and sealing arts are boosted between +120% to +500% effectiveness based on complexity and prior prep (e.g., pre-marked seals or chakra loops).
"Sure-Hit" Principle:
All techniques, once initiated, will land unless countered with equal-rank space-time manipulation (e.g., Flying Thunder God, Kamui). This applies to Genjutsu, Rasengan variants, and even Fuinjutsu applications.
Time Perception Control:
While the actual time flows normally, Seijuro can modulate time perception for his targets, creating windows of paralysis or acceleration to ensure lethal follow-through.
🧨 Weaknesses / Limitations:
Chakra Cost: Prohibitively high. Requires roughly 40–60% of Seijuro's total reserves to open and maintain. Sustained for a max of 3 minutes without outside chakra feeds.
Anchor Vulnerability: If any of the four external barriers are destroyed, the domain begins collapsing (15-second countdown).
🧩 Activation Sequence:
Precondition: Must have placed four anchor marks (Flying Thunder God formula-enhanced) in advance.
Handseals (Rapid): Tiger → Boar → Dragon → Dog → Rat → Seal
🔮 Visual Appearance (Interior Realm):
A starless, endless black sky, with slowly rotating sealing arrays above.
The floor is composed of hexagonal polished obsidian plates inscribed with glowing runes.
Gravity obeys Seijuro's intent—he can suspend opponents mid-air, bend floor panels, and split terrain with chakra pulses.
