A new promotional video for The Summer Hikaru Died Season 2 has been released, offering the first glimpse into the continuation of the unsettling supernatural mystery. The trailer, published on YouTube, confirms that CygamesPictures, the studio behind the first season, will return to animate the upcoming 12-episode run, set for a Summer 2025 premiere.

The series, adapted from Kakeru Sumida's manga of the same name, plunges viewers into a rural Japanese town where Yoshiki Tsujinaka grapples with the horrifying reality that his best friend, Hikaru Indou, is no longer human after a mysterious disappearance. The trailer teases the deepening psychological and cosmic horror as Yoshiki navigates his complex relationship with the monstrous, yet seemingly innocent, Hikaru, who desperately wishes to avoid harming his friend.

Season 1 concluded with Yoshiki accepting the monstrous Hikaru's plea for secrecy, setting the stage for a narrative that explores themes of tragedy, unrequited love, and the philosophical implications of coexistence between humans and otherworldly beings. The new PV hints at the escalating stakes and the potential for further body horror and mythological elements, aligning with the manga's exploration of curses and darker folklore.

With a MyAnimeList score of 8.02 from over 106,000 voters, The Summer Hikaru Died has already established a strong following for its unique blend of BL undertones, intense psychological dread, and striking visual design. CygamesPictures' previous work, including Princess Connect! Re:Dive and The Idolmaster Cinderella Girls, showcases their ability to handle both character-driven narratives and fantastical elements, making them a suitable choice to continue this disturbing tale.
