Jujutsu School Permit Stamping Guide: Exact-Grade Stamp Rule
Jujutsu School (Anomaly) permit stamping: apply the stamp matching the visitor's exact grade, reject anything that feels off by closing the shutter door, and see what a wrong stamp costs.
Quick answer
Read the grade the visitor claims or shows on their documents, then apply the one stamp that matches it exactly — the game requires you to “apply the corresponding stamp for their exact grade.”
- The stamp system activates after the first quiet night: “Night one is clear. Students from various sorcerer grades will now be arriving.”
- Exact matching matters because it “optimizes the barrier to handle their cursed energy capacity.”
- An in-game tutorial prompt repeats the rule during play: “Use a stamp that corresponds to visitor's grade.”
Approve: stamp verified visitors through
Approval is the final action after a visitor passes inspection — the night-shift job is “checking their IDs and stamping their permit papers” so real visitors can pass the cursed barrier. Visitors ask for it directly: the first-shift teacher says, “I need my entry pass stamped. I'm a teacher, not a student,” and Gojo says, “Anyway, stamp me through.” Once the visitor checks out as real and their grade or status is known, apply the matching stamp and admit them; the stamp itself is what lets them pass.
One exception: the very first visitor, the teacher on the opening shift, only needs an entry pass stamped — the exact-grade rule is not introduced until after that first quiet night.
Reject: shut the shutter on anything that feels off
The briefing defines the rejection action: “If someone approaches and something feels off, do not let them in. Close the shutter door immediately and stay completely still.” The threat is explicit — curses “categorized as Anomalies trying to get into the school” — but the rule cuts both ways: “do not mistakenly reject an actual student. We need every single one of them for a highly classified operation.” A clean rejection logs a “Visitor rejected.” message; rejection is a shutter decision, not a stamped outcome. The game describes rejecting as not letting the visitor in and closing the shutter rather than naming a dedicated reject button.
One player checked an ID badge, saw that “her head was moving like this, man,” refused the visitor, and later confirmed the call: “Oh, thank god I rejected that girl.”
What a wrong stamp costs
The penalty is a double hit: “Using the wrong stamp will ruin both their performance and your shift performance,” with the briefing adding, “We cannot afford errors tonight.” A wrong-grade stamp also produces on-screen feedback reading “Wrong grade zero.” The message itself does not explain what the “zero” refers to or the scoring behind it, so treat the ruined visitor performance plus ruined shift performance as the concrete cost. Some players have guessed that repeated mistakes make an anomaly more likely to appear, but that remains unconfirmed player theory, not stated game behavior.
Keep the line moving
Stamping decisions are meant to be quick. The briefing pairs verification with pace — “Keep the line moving, but do not drop your guard” — and Gojo warns that hesitation carries its own risk: “while you're staring at that paper, a curse could be sneaking up right behind you.” Decide, stamp or shut the door, and move on; lingering over the paperwork leaves the booth exposed.
Visitors observed in play
Comparison
| Visitor | What They State Or Show | Stamping Decision Observed |
|---|---|---|
| Teacher (first shift) | “I'm a teacher, not a student” | Entry pass stamped before the grade-stamp rule is introduced |
| Panda | “I'm a secondyear student. Don't worry. Principal Yaga signed off on this.” | Checked and stamped through |
| Gojo | Identified as “your special grade” | Stamped through; players ask “Use any stamp for special grade?” — currently unresolved |
| Various students | Grades stated during play, e.g. “You are a grade four.” and “I already knew he was grade one too.” | Stamped per the exact-grade rule |
Two gaps to keep in mind: only grade four, grade one, and special grade stamps have been observed in play so far, plus Panda's self-described second-year status, so a full stamp-to-grade table is not possible yet. Special grade is also unresolved — the briefing demands the exact-grade stamp for every visitor, but players ask whether a special-grade visitor accepts any stamp. Check the stamp tray against the visitor's stated grade in-game rather than assuming either way.
The game “is currently a work in progress and in alpha phase,” so recheck stamp options, feedback messages, and rejection behavior after mechanic updates.
