Tears of Themis Episode 15 Guide: Sin and Retribution Walkthrough

In contrast to other titles within HoYoverse’s live service lineup, which receive updates consistently every six to eight weeks, major updates for Tears of Themis are far less frequent, occurring only three or four times annually. This sporadic release schedule, compounded by the fact that international players remain one year behind the domestic launches in China, creates a unique situation where fans have insight into upcoming content yet remain uncertain about the timing of its global debut.

However, there is exciting news: Tears of Themis Episode 15: Sin and Retribution was globally launched in late August 2025, much to the delight of fans. This latest installment, the sixth chapter of the Gladiolus Valley arc and part of the series’ second main story arc, does not tie up loose ends just yet. Instead, it leaves players with intriguing lore hints, continuing from Episode 14, which was released in two parts earlier this year between January and April.
