Red Chat Ritual Ending 404: How to Get It

What is End 404 in Red Chat Ritual?

End 404 is the ninth numbered-style ending achievement on Steam for Red Chat Ritual – TSUMIMI TIME (alongside End 1 through End 8). The trophy is not hidden in the HTML snapshot taken on 2026-10-24.

See how End 404 fits the completion set at /endings/all-endings/ or the full achievement roster at /guides/achievements/.

What do community guides say triggers End 404?

Official materials reviewed on 2026-10-24 do not publish a step-by-step script for End 404 beyond the achievement string. Two independent community ending write-ups agree on a final deduction fail:

Community maps Chapter 3 to roughly Days 12–15 in walkthrough tables (Guidexon walkthrough); that day range is not an official menu label.

End 4 variant (related final deduction): Guidexon and Treyexgaming also report that one specific swapped entry at the same final deduction, with the other entries mostly correct, leads to End 4 instead of End 404. That branch is summarized on /endings/all-endings/ because it shares the final gate; the entry itself is folded there.

Is End 404 intended or a secret true ending?

Unknown from official text. The Steam store lists multiple endings but never ranks one as “true.” The End 404 name and description are flavor only; they do not state developer intent. Community guides treat End 404 as a failure or joke route you can trigger on the last deduction, not as proof of a hidden canon ending.

If you are completion hunting, End 404 still counts toward All Endings Completed on Steam like any other End N trophy.

What should you do before the final deduction?

Practical steps that are official or generic:

• Create a home-screen save before the last stream or deduction block, matching FAQ advice to save before streams (official FAQ EN).
• Keep one slot for a clean finish and another if you want to test End 404 or End 4 branches without replaying from Day 1.
• Read /guides/save-and-fast-forward/ for Ver.1.0.1 Ctrl skip behavior on replays.

This wiki has not independently confirmed which blank fields appear on the final deduction screen; only the fail condition above is two-source.
