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.
Right from the inception of the project, series director Ryohei Takeshita envisioned HikaNatsu as an 'enshutsu anime'—a show where the immediate sensorial experience, mise-en-scène, and unique atmospheric tools take center stage. Produced at CygamesPictures, the adaptation translates original author Mokumokuren’s chilling rural horror into an audiovisual nightmare. Sound plays a monumental role, orchestrated by legendary sound designer Kouji Kasamatsu, who uses oppressive ambient noises, cicadas, and diegetic sound effects to mirror the psychological suffocation of protagonist Yoshiki.
Alongside 'dorodoro' creature animation by Masanobu Hiraoka and a narrative that balances uncanny body horror with a non-romantic queer core, the anime has captivated audiences worldwide. With a second season officially announced, the creative team continues to redefine the boundaries of modern television horror.
