Sister Other Paranoia Launch Times
Convert the official unlock clock across regions—and why Steam still says August 14.
One unlock moment, many calendar days
Sister Other Paranoia (Steam app 4240150) is a dark visual novel from HazeDenki, with scenario and direction by nyalra, published worldwide by Serenity Forge. Steam storefront calendars often show a planned release date of August 14, 2026. Official timing reported through regional launch coverage—summarized in Game8’s release-time table—places the unlock at August 14, 8:00 PM Pacific Time / 11:00 PM Eastern Time, which is the same instant as August 15, 3:00 AM UTC and August 15, 12:00 PM Japan Standard Time.
That single moment is why friends argue about “the 14th versus the 15th.” They are usually describing the same Steam unlock with different local clocks. This page is the conversion sheet. For the broader “planned versus final” Steam wording, keep Release Date open beside it.
Official-style regional launch table
Use the following as orientation for the reported worldwide unlock. Always re-check Steam app 4240150 in the final days if the store countdown moves.

|---|---|
| United States (Pacific) | Friday, August 14, 2026, 8:00 p.m. |
| United States (Eastern) | Friday, August 14, 2026, 11:00 p.m. |
| Universal Time (UTC) | Saturday, August 15, 2026, 3:00 a.m. |
| United Kingdom | Saturday, August 15, 2026, 4:00 a.m. |
| Central Europe | Saturday, August 15, 2026, 5:00 a.m. |
| South Africa | Saturday, August 15, 2026, 5:00 a.m. |

If your city sits outside those labels—for example India Standard Time, Korea, or a U.S. Mountain/Central zone—convert from the UTC row rather than guessing from a neighbor’s screenshot.
How to convert without getting lost
- Anchor on August 15, 2026, 03:00 UTC (or the matching PT/ET pair above).
- Open any trustworthy timezone converter and enter that UTC stamp.
- Note whether your result lands on Friday the 14th or Saturday the 15th locally.
- Set a personal alarm a few minutes early so Steam client refresh lag does not ruin the first click.
- On unlock day, open the official product page—not a search snippet—and confirm the buy button for app 4240150.
Daylight-saving quirks matter less for this particular window than simply knowing which calendar date your city prints. Pacific and Eastern U.S. players still see August 14 evening; Japan, Australia, and most of Europe see August 15.
Steam unlock versus calendar-date confusion
Steam’s product header can keep showing August 14, 2026 while press and regional tables describe an unlock that is already Saturday morning in UTC and JST. Both can be honest:
- The store date chip often follows a publisher-facing or U.S.-friendly calendar day.
- The clock time is a worldwide simultaneous unlock expressed in local zones.
- A late-night Americas evening is mathematically the next morning in UTC and East Asia.
Do not treat “August 14 on Steam” and “August 15 noon in Japan” as two competing release schedules unless the store itself changes. Treat them as two labels for one moment until Serenity Forge or HazeDenki posts a revision.
Price, platforms, and what unlock actually means
Public coverage places the launch price around $9.99 USD. Regional taxes and currency conversion appear at checkout. Platforms named for this Steam window are Windows and macOS; see Platforms and System Requirements if hardware is your open question.
Unlock means the Steam purchase and download path becomes available for that app ID. It does not mean every mirror, news post, or wishlist email arrives in the same second. It also does not invent console ports, cloud exclusives, or mobile builds.
Demo, Discord, and launch-week habits
A free demo has been discussed through the HazeDenki Discord community often nicknamed around “Don’t tuch grass” / Don’t touch grass messaging. Demo availability can differ from the full-game unlock clock. Bug reports for pre-release builds also belong on that Discord, not in invented wiki issue trackers.
Practical launch-week habits:
- Wishlist early so Steam can mail availability alerts.
- Confirm disk space and OS notes on system requirements.
- Read How to Buy before gray-market key shops look tempting.
- Use Getting Started for first-session orientation after install.
- If you stream or upload, Steam’s page text allows streaming and uploads—including spoilers—and monetization without prior permission, but your audience’s comfort with mature themes still matters.

Tone check before you stay up for the unlock:
What this page will not invent
We will not invent staggered region locks, secret early-access tiers, console timed exclusives, or minute-by-minute store CDN delays. We will not invent endings, route maps, or “best time to buy for a hidden scene.” Sister Other Paranoia’s marketing leaves the sibling future for players to witness; launch times only tell you when the Steam door opens.
If the planned stamp moves, trust Steam and official HazeDenki / Serenity Forge posts first, then re-convert from the new UTC anchor. Until then, set your alarm from the table above and stop arguing about the calendar label.
Frequently Asked Questions
Quick answers to the most common questions.
What is the exact Sister Other Paranoia launch time?
Reported official timing is August 14, 2026 at 8:00 PM PT / 11:00 PM ET, equal to August 15, 2026 at 3:00 AM UTC and 12:00 PM JST. Re-check Steam if the planned date changes.
Why does Steam say August 14 if Japan sees August 15?

How do I find my local unlock time?
Convert August 15, 2026, 3:00 AM UTC with a timezone tool, or use the regional table on this page, then confirm on Steam near launch.

Wishlist on Steam, then use How to Buy and Getting Started for purchase and first-session steps. Release Date explains the planned-date wording.
