Fans of the gripping supernatural mystery Hikaru ga Shinda Natsu, known in English as The Summer Hikaru Died, have reason to celebrate. It has been officially confirmed that a second season is now in active production. This thrilling announcement follows the critically acclaimed first season, which captivated audiences worldwide after its premiere on July 6, 2025. Distributed globally via Netflix with multi-language subtitles, the series quickly garnered a dedicated international fanbase, drawn to its unique blend of haunting supernatural elements and profound psychological drama.

Based on Mokumokuren's original manga, which has been serialized since August 2021 on Kadokawa Shoten's Young Ace UP website, the anime delves into the unsettling narrative of protagonist Yoshiki and the enigmatic entity impersonating his friend, Hikaru. The series expertly crafts an atmosphere of suspense, exploring complex themes of identity, loss, and existential dread through its intricate storytelling and distinctive hand-drawn animation.

The original manga continues to thrive, reaching its seventh volume as of July 4, 2025. Yen Press skillfully handles the English licensing for both the manga and its expanding light novel adaptation. Authored by Mio Nukaga, the light novel series, which debuted in December 2023, has further broadened the franchise's appeal, cementing its status as a multi-platform phenomenon.

Production Details

Behind the scenes, the visionary Ryōhei Takeshita leads the production as director and series composer. He also contributes to character design alongside Yuichi Takahashi, with additional animation expertise from Masanobu Hiraoka. The first season's memorable opening and ending themes, 'Saikai' by Vaundy and 'Anata wa Kaibutsu' by Tooboe, respectively, perfectly encapsulated the series' eerie and suspenseful essence.
