Jujutsu School Final Boss Guide: Bell, Geto Fight & Ending

Quick answer

The final encounter hits at the end of the night-shift sequence at Jujutsu High, after you've spent the shift inspecting visitors and stamping permits. Before it starts, Gojo warns that the cursed energy around the school is abnormal and hands you a bell. The survival rule that decides the fight: ring the bell the moment anything resembling Suguru Geto appears — it disrupts the entity's cursed energy and stuns it long enough for you to make it out alive.

• Access: the encounter sits at the end of the shift progression. Full-game runs are currently labeled SHIFT 1-8 or SHIFT 1-12, so check the shift count in your own game to know how close you are.
• Required item: Gojo's bell, given to you with the warning to ring it immediately if anything out there resembles Geto.
• Goal: stun the entity with the bell and survive. Runs end either in escape or with the entity defeated — the bell is your survival tool either way.

The intruder that looks like Geto

The final threat is an anomaly that resembles Suguru Geto — the game frames it as a mimic or monster, not the anime character himself, so don't go in expecting a standard anime-faithful duel. It appears near your booth, announcing "there are a few cursed objects here that require my attention," and openly mocks the bell in your hand. The resemblance itself is your trigger: the moment a figure that looks like Geto shows up, that's your cue to ring. Its exact in-game name isn't confirmed; walkthroughs call it Geto, or more carefully a Geto-resembling anomaly.

The survival rule: ring the bell, then keep ringing it

Ring the bell on sight. It disrupts the entity's cursed energy and stuns it, creating the window you need to make it out alive. The entity taunts that "a mere bell won't be enough to save you," and gameplay footage backs that up — it can regain its shield or recover between stuns. The most common way to lose is treating the bell as a one-time answer: it's a survival tool you use every time the entity presses in, not a one-hit kill. How the fight finally resolves is currently inconsistent between runs — escape after a stun in some, a full defeat in others — so plan around the stun window rather than expecting any single ring to end things. No detailed phase-by-phase attack breakdown is documented; the repeatable plan is bell on sight, every time.

Winning and what comes after

Winning means the Geto-resembling entity is destroyed. Playthroughs describe Geto evaporating, along with Seeker, and the game then presents a true ending before dropping you into an overtime state — "so, this is after again." That ending label and overtime transition are the whole documented aftermath; no separate reward screen or unlock list has been shown. The same applies to access: the encounter's only stated requirement is reaching the end of the shift progression.
