The Summer Hikaru Died

The Summer Hikaru Died is a dark, supernatural mystery TV anime with BL elements, set in a modern backdrop and produced by CygamesPictures. The series is directed and series-composed by Ryohei Takeshita, adapting the manga by モクモクれん. Centered on Hikaru Indou and Yoshiki Tsujinaka, the series delivers a distinctly atmospheric blend of suspense and dark aesthetics, marking a compelling entry in the supernatural BL anime genre.

Set in a quiet, isolated village nestled in rural Japan, The Summer Hikaru Died follows the story of two childhood best friends, Yoshiki Tsujinaka and Hikaru Indou, whose bond has been the cornerstone of their entire lives. Growing up side by side in this remote community, the two were virtually inseparable — until one summer changes everything. After Hikaru ventures into the mountains alone and returns, Yoshiki can't shake the unsettling feeling that something is deeply, fundamentally wrong. The person standing before him looks like Hikaru, speaks like Hikaru, and carries all of Hikaru's memories — yet something indefinable feels off. Is it simply Yoshiki's imagination running wild, or has something unknown quietly slipped into the place where his closest friend used to be? Blending supernatural unease with the tender ache of human connection, this story explores what it truly means to know someone — and what happens when that certainty begins to crumble.
