The Summer Hikaru Died / HikaNatsu’s anime was conceptualized around Ryohei Takeshita’s adventurous direction, but without losing sight of the author’s core ideas. With a sequel on the horizon, it’s time to learn more about a fascinating production. In the industry, artists often use evocative terminology like sakuga, layout anime, or bijutsu anime to highlight the core centerpiece of an experience. Right from the inception of The Summer Hikaru Died, series director Ryohei Takeshita had something clear: it was going to be an enshutsu anime—a show emphasizing the immediate experience through tricky mise-en-scène and unique tools, where the sensorial aspect becomes the undeniable centerpiece.
In interviews with outlets like Anime Corner, CyberAgent producer Manami Kabashima and Kadokawa producers Chiaki Kurakane and Toshinori Fujiwara detailed how they settled on Takeshita and Cygames Pictures. Takeshita’s clear vision gave producers confidence. Rather than seeking a meek director who’d bend to their choices, they understood that capturing HikaNatsu’s appeal relies on intangibles best left up to a brilliant creator. Takeshita wasn't just series director; he also took on series composition and wrote half the scripts, ensuring a tight grip on the narrative’s thematic core.
The premise is chillingly simple: in an isolated rural village, a high school boy named Yoshiki notices that his best friend Hikaru went missing during a secret village ritual and returned... changed. Whatever inhabits his skin now is an eldritch supernatural entity with no human morality. This direct reenactment of the Swampman thought experiment forces characters and readers to ponder what truly makes a person. As author Mokumokuren has emphasized, the series is a non-romantic queer story that rejects normative tropes, celebrating the allure of the abnormal and monstrous rather than "de-monstering" the entity.
A massive part of HikaNatsu’s dread comes from its sound design, spearheaded by legendary sound designer Kouji Kasamatsu under the non-standard credit of ongaku enshutsu. From the incessant chirping of cicadas to jarring clangs and distorted onomatopoeia, sound acts as an oppressive physical weight. Similarly, Masanobu Hiraoka brought his mastery of morphing dorodoro animation to life, giving "Hikaru" a mesmerizing, gooey, cellular horror aesthetic that keeps both Yoshiki and viewers spellbound.
The supporting staff delivered stellar atmospheric episodes. From Mitsuhiro Oosako’s textural meat motifs in episode #02 to Asaka Yokoyama’s chilling pacing in episode #03, and contributions from directors like Wang Chihsia, Ryouta Kawahara, Ryo Ando, and studio NUT, the production maintained a cohesive, suffocating unease. Despite schedule strains, Takeshita’s hands-on approach in the finale solidified HikaNatsu as a landmark horror adaptation. With a sequel officially announced, fans can eagerly await the continuation of this bewitching and deadly tale.
