The Island Suspense event in the game Tears of Themis introduces a unique twist, distinguishing itself from previous special events throughout its five-year journey. Unlike its forerunners, this event not only extends the narrative beyond the Gladiolus Valley arc but is also integrated into the main storyline. This means that it will remain accessible indefinitely, ensuring that newcomers and players catching up on the plot won’t miss essential elements of the game.
Tears of Themis: Exploring Island Suspense Encryption Ciphers
The event features a total of 90 entries in the Clue Collection under the Encryption category. Of these, 69 can be accessed by inputting specific cipher texts into the Deciphering menu. As of now, players have uncovered 47 of these codes, and while we provide a list below, we encourage players to explore the game to find the remaining 21 entries for a complete Encryption codex by the event’s conclusion.
Unlocking all 69 ciphers fulfills the “Painstaking Investigator” task, which rewards participants with 10, 000 Stellin. Importantly, there is no rush to finish the decryptions before the October 17, 2025 deadline; as long as the Tears of Themis servers remain active, players can continue to enter these codes into the Deciphering device for rewards.

Decoding the Encrypted Messages in Tears of Themis: Island Suspense
To start your journey in decrypting codes, navigate to the Island Suspense event page within Tears of Themis. During the initial event period, you can access this page via the icon on the main screen, but it will later be permanently located under X-Note > Events.
Upon reaching the event page, click on the Terminal icon located at the bottom left of the screen.
From there, select the Deciphering option from the menu and input your cipher text into the text box. Click Decrypt to unveil the message.
If you encounter challenges getting a cipher to register, retyping it may help as copy-pasting can sometimes lead to errors in recognition by the game.
(Note: On Android devices, the system may confuse these ciphers as passwords, which can be bothersome, but you can ignore that feature.)
