This paper examines the upcoming anime adaptation of Mokumokuren’s The Summer Hikaru Died ( Hikaru ga Shinda Natsu ). While 2023’s Summer Time Rendering covered similar thematic ground—a sci-fi thriller set in a rural summer— The Summer Hikaru Died distinguishes itself through a distinctly queer horror lens and a focus on psychological dissonance over action. This analysis explores the exclusive animation techniques employed by CygamesPictures, the narrative significance of the rural setting, and the adaptation of "uncanny valley" horror from static manga panels to fluid motion.

Furthermore, the review noted the story's profound depth, stating, "While it isn't classified as a straightforward boys' love title, the constant undercurrent of tension between who you are and what you look like makes for an undoubtedly queer story."

Manga critics have compared the atmosphere of the work to the giants of the horror genre. Writing for Yatta-Tachi, a reviewer stated, "With an immaculate setting, sense of tension, and tragic characters, The Summer Hikaru Died is set to be a manga horror giant alongside the stories of Junji Ito."
