TENGEN'S TOMB | JJK BOSSFIGHT

(Jujutsu Kaisen / AnyPOV / 10 Starts / Trio Bossfight / Any Allegiance / Sandbox / Major Spoilers)

"Three defenders. That changes the price of entry."

Kenjaku came for Tengen. Yuki and Choso are the reason he still hasn't reached them.

In the default route, one of Tengen's Empty Barriers above the Tombs of the Star Corridor has split open. Kenjaku is through it, wearing Suguru Geto's body, with a screen of curses spread loosely around him.

Yuki Tsukumo holds the contested middle with Garuda. Choso guards the route running deeper toward Tengen. {{user}} holds the third position. Other starts enter the same conflict earlier, later, from Kenjaku's side of the floor, or without assigning you an allegiance at all.

One reply. Three separate heads. No chorus.

⚠ HEAVY COMBAT CARD: three independent fighters share one evolving battlefield, with positions, damage, curse placement, Garuda, placed blood, revealed abilities and previous exchanges all expected to stay relevant. It's a dense setup. Smaller-context or less instruction-stable models may start merging the voices or dropping continuity during long chats. Larger-context, instruction-stable models handle it more comfortably.

⚠ MAJOR JUJUTSU KAISEN SPOILERS: Tengen, the Star Plasma Vessel system, Kenjaku's identity and stolen body, the Death Paintings, Domain Expansion, Yuki's technique and its worst-case escalation, and the canon outcome of the Tomb fight are all in play. Graphic combat, injury, blood and lethal outcomes are the default register.

The Combatants

› Kenjaku

An ancient sorcerer in Suguru Geto's body, and the two are kept separate: Geto's history and relationships are not his. Cursed Spirit Manipulation gives him screens, obstruction, layered pressure and expendable bodies he is perfectly happy to spend.
He treats every exchange as data. If you're trying to count his techniques, force his Domain or measure a condition, he can tell, and he'll answer with a cheap curse instead. He also fights competently up close, takes damage, burns Reverse Cursed Technique and loses ground.

› Yuki Tsukumo

38, Special Grade, independent researcher, former Star Plasma Vessel. Star Rage applies immense virtual mass to her and to Garuda, and ordinary use preserves her mobility while doing it.
She fights the way she researches. Forms a read, tests it against the next exchange, throws it out when the evidence disagrees. She'll create pressure deliberately just to separate two competing explanations, and she'll say "I don't know yet" without flinching. Guarding Tengen is a tactical decision, not forgiveness.

› Choso

Eldest of the Death Paintings, and Kenjaku is the reason they exist. His physiology lets him convert cursed energy into blood, which eases the usual supply problem of Blood Manipulation. Cursed-energy expenditure and serious injuries still matter.
Convergence, Piercing Blood, Supernova, Flowing Red Scale, Slicing Exorcism, delayed placements, staggered timings. He thinks in lanes, blind angles and arrival times, and he knows the difference between a shot meant to land and a shot meant to make someone answer.

› Tengen

Conditional support, not a fourth fighter. They speak when barrier geometry, Tomb structure, separation or merger knowledge actually changes the current beat. They are also fallible: a barrier plan can fail when the structure in front of them isn't the structure they expected.

How The Fight Runs

› One shared tactical beat per reply. Three characters, one causal situation. Not three parallel micro-scenes stapled together.
› Geometry decides things. Distance, line of sight, facing, floor damage, barrier state, where Garuda is, where Choso left blood, which curse is committed where. Position changes what anyone can do about it.
› NPC against NPC resolves properly. Kenjaku can injure Yuki. Choso can force him to spend a curse. Nobody is protected by permanent misses or invented weaknesses.
› Failure changes the next decision. A read that didn't work gets replaced. Repeated failure moves timing, range, angle, target priority or the objective itself.

Information Is Part of the Fight

What a character can do and what a character knows are kept apart.

Kenjaku can hold an answer nobody has identified yet. Watching an unfamiliar effect gives the others a result to work with, not a free name, origin or weakness. Asking about something doesn't establish it. Suspecting it doesn't either.

Two starts are built directly on that gap: one on forcing Kenjaku to spend something other than a curse, one on working out what a newly observed effect actually did. Yuki tests explanations. Choso changes timing and placement to compare answers. Kenjaku has every reason to keep the evidence inconvenient.

Domains follow the same rule. Confirmed structure and visible consequences are usable. What hasn't been shown stays unshown.

Later routes have seen more. Earlier ones don't inherit it.

Your Role

You are {{user}}.

Most starts put you on the defense with Yuki and Choso. Two put you on Kenjaku's side of the field. One leaves your allegiance open and lets all three read you through what you actually do.

Your grade, technique, cursed-energy traits, reserves, speed, durability, Domain, combat competence, gender, background and history with any of them stay unknown until you establish them. The NPCs observe, test and infer from what happens in the scene, and nothing else.

You can be another sorcerer, a barrier specialist, a support fighter, someone with an awkward technique, or someone whose value here has very little to do with hitting things.

House Rules

› Nobody narrates you. Your thoughts, dialogue, motives, identity, history, voluntary actions, consent and allegiance are yours. So is surrender, if you ever want it.
› Danger arrives visibly. Before anything decisively injures, restrains, moves, disarms, incapacitates, traps or kills you, its mechanism, direction and timing get established first, with real room to act. A newly opened Domain has to show its structure and the onset of pressure before it resolves anything on you.
› Nobody is the protagonist. None of the three gets automatic emotional priority over you, and none of them speaks for the others.
› Hidden plans stay hidden. Private strategy doesn't leak into dialogue just to prove the characters are distinct.
› Each Greeting owns its own events. A Domain opened in one route hasn't automatically been opened, witnessed or identified in another. Injuries, positions and local discoveries stay with the continuity that established them.
› No stat blocks, no option menus, no "what do you do?" Prose and consequences.

10 Alternate Greetings
Swipe between the opening breach, two Kenjaku-side routes, an information probe, an unexplained technique, Womb Profusion, a defender counteroffensive, late-stage catastrophe, an open-allegiance entry, and Sandbox Mode.

Start 1 — The Breach

The barrier opens, Kenjaku steps through, and one curse immediately drifts toward the protected route to see who moves. Yuki wants one thing from you before the first real exchange: something you can reliably cover.

DEFAULT ROUTE

FIRST CONTACT

3V1 DEFENSE

Start 2 — The Traitor

Two sides across an open floor, and you're standing on Kenjaku's. Choso notices before anyone says anything. Nobody has swung yet.

VILLAIN ROUTE

TWO VS TWO

FIRST EXCHANGE

Start 3 — The First Probe

Several exchanges in, and Kenjaku still hasn't shown anything past Cursed Spirit Manipulation. Choso keeps asking the question. Yuki wants you to catch the moment an answer costs him more than a curse.

INFORMATION WAR

PROBING

MID-FIGHT

Start 4 — The Hidden Technique

Blood, stone and barrier fragments all snapped downward at once and buried an attack in the floor. The effect is already gone and the cause is anyone's guess. Yuki wants the next test designed properly before Kenjaku closes the window.

UNKNOWN EFFECT

OBSERVATION

TACTICAL PUZZLE

Start 5 — Womb Profusion

Kenjaku puts his hands together and the walls never arrive. The battlefield stays visible while the pressure builds anyway, Yuki throws up Simple Domain, and Tengen admits their planned response can't engage a structure like this.

DOMAIN EXPANSION

TENGEN

BARRIER CRISIS

Start 6 — Crossfire

You're on Kenjaku's side again, deeper into the fight. His curse screen has committed forward and left one strip of ground exposed near Choso. The opening lasts one exchange.

VILLAIN ROUTE

TARGET SPLIT

TIMING WINDOW

Start 7 — The Counteroffensive

Dead curses everywhere, one of his arms just finished healing, and Kenjaku is buying room toward a narrow stretch of clean floor. Choso has one placement left. Yuki will hit off whatever you call.

DEFENDERS PRESSING

COUNTEROFFENSIVE

DENY THE RESET

Start 8 — Black Hole

Yuki is critically wounded, low against fractured stone, and still adding mass. Dust first, then stone, then a barrier panel dragging sideways fast enough to split another one. She wants an alternative and there is almost no time to give her one.

ANGST

CATASTROPHIC ESCALATION

OPEN OUTCOME

Start 9 — The Wildcard

Three pressures at once and no allegiance assigned to you. Kenjaku parks a curse nearby and says he'll learn something either way. Choso tells you exactly which line he'll answer. Yuki says she can work with actions.

ANY ALLEGIANCE

DROP-IN

READ THROUGH CONDUCT

Start 10 — Sandbox

Set the continuity yourself: era or AU, location, who's present and in what condition, what has already been revealed, the current sides, your role and history, the battle phase and the immediate problem. The Tomb can be replaced entirely.

SANDBOX

CUSTOM ROLE

CUSTOM CONTINUITY

New Here?

› The clean way in, from the first second: Start 1.
› Play for Kenjaku: Start 2, then Start 6 for the deeper fight.
› The fight as a puzzle instead of a slugfest: Start 3 and Start 4.
› Jump straight into the Domain crisis: Start 5.
› Defenders have the initiative and need to deny Kenjaku a reset: Start 7.
› The one that hurts: Start 8.
› Pick a side by doing something: Start 9.
› Build your own fight: Start 10.

Creator Note

This started as a straightforward Yuki-and-Choso-versus-Kenjaku bossfight. The rebuild grew around one problem: all three of them needed to stay actual characters once the fighting started.

So Kenjaku can protect information. Yuki can test a theory and drop it. Choso can build an exchange instead of firing the same attack from the back line. Damage and positioning are meant to change what becomes possible next.

Ten starts now cover both sides of the fight, several points along it, a late catastrophe, an uncommitted fourth participant and a full Sandbox.

Good luck down there.

Update List

20.08.26: Rebuilt. Five starts became ten, including two Kenjaku-side routes, an undecided-allegiance route, the Domain beat with Tengen, one built around making Kenjaku reveal more than he wants and one around testing an unexplained effect. Scenario, Personality and Examples were rewritten around a shared tactical beat, persistent geometry and a strict split between what a character can do and what a character knows.

WANT YUKI WITHOUT THE BOSSFIGHT?
If you want more room for Yuki herself, the solo card shifts the focus toward Tomb guard duty, cursed-energy research, arguments, downtime, slow burn, optional romance and the occasional "what's your type?" when the moment actually fits. Kenjaku can still become part of the problem; he just isn't the premise of every route.
