Keep the Door Locked Ending 4: Katana Visitor Route

What Ending 4 actually confirms

ENDING 4 was added around August 7, 2026. Its official badge text is unusually specific: Trust a man with his katana. But something was already standing there, watching you, waiting to run. That sentence is the entire verified route clue. It confirms a katana-carrying visitor, a trust decision, and a second threat or presence that is already inside or near the room when the trust moment happens.

Public award counts for Ending 4 are extremely low compared with Ending 1. Treat the route as rare and incompletely documented. Do not invent a day number, dialogue script, or guaranteed spawn timer. Use this page to preserve a clean attempt: recognize the visitor, decide deliberately, and watch the room for the “already standing there” beat instead of celebrating the trust choice alone.

How I Got ENDING 4 in Keep the Door Locked

Prepare before you chase the katana

Build a stable night loop first. Read How to Play, practice Camera and Door Decisions, and know how to survive Door Breaker and Shadow Figure pressure. Ending 4 is a poor first-session goal. A player who cannot finish a calm camera check will not separate a katana visitor from a deadly lookalike.

Keep the run clean. Do not mix this attempt with Blood Money grinding, Dream Room tourism, or random Easter-egg hunting. One ending question per session keeps your notes interpretable. Log progress in the Ending Tracker and compare sibling routes in All Endings.

Recognize the trust decision

When a man with a katana appears at the door, slow down. Use cameras and the peephole or door view if available. Confirm the weapon, posture, and any mismatch between what he says and what the hallway shows. The badge requires trust, so the route likely fails if you refuse the interaction, slam the door prematurely, or treat him as a generic anomaly without reading the prompt.

Trust does not mean abandon observation. The second half of the badge warns that something is already present and waiting to run. After you accept or assist the katana visitor, immediately re-scan the room: corners, beds, bathroom, window stages, and any shadow or hider state. A successful trust choice can still fail if the pre-existing presence is ignored.

Room vigilance after the choice

The “already standing there” line is the unique Ending 4 risk. Other endings focus on survival length, a skeleton discovery, or a grandma key. This one ties a visitor decision to a concurrent room threat. After the trust moment:

1. Recheck cameras before celebrating.
2. Sweep the room for a hider, shadow, or silent watcher.
3. Do not turn your back on the doorway while the visitor event resolves.
4. Note whether something flees, attacks, or simply reveals itself.

Use Room Hider, Shadow Figure, and the anomaly checklist if the second presence matches a known threat family. If it does not match, write the raw observation instead of forcing a label.

Separate Ending 4 from similar visitors

Kindness, grandma, pizza rat, Juan, and the dog are different badge leads. A man with a blade is not automatically Ending 4 unless the trust choice and the watching presence line up with the badge wording. Compare encounters in the Visitors Guide and keep Ending 3’s Grandma Key route on a different research day.

If the katana visitor never appears, do not fill the gap with a fabricated spawn schedule. Rotate calm observation runs, keep rules intact, and treat rarity as a reason for patience. Low award counts mean false guides spread quickly — reject any claim that requires an executor, paid key, or account login outside Roblox.

After you earn or miss the badge

If ENDING 4 unlocks, record the visitor details, trust choice, and what was already in the room. If it fails, record which half broke: the trust decision, the room scan, or an unrelated anomaly kill. Update Badge Tracker only when the badge actually awards.

Ending 4 expands the story space of Keep the Door Locked without replacing the ten-day baseline. Master cameras first, then hunt the katana route with deliberate notes. Trust the man when the evidence supports it — and assume something else may already be watching.
