A Dazzling Neon Collection for The Summer Hikaru Died: Where Anime World Meets Street Fashion!

Mokumokuren’s globally acclaimed work The Summer Hikaru Died (Hikaru ga Shinda Natsu), which left its mark on screens with its anime adaptation last year, has signed a new collaboration that will excite its fans. The series has joined forces with the popular design brand neneon to prepare a special product collection where neon colors and modern aesthetics take center stage. Opened for pre-order via the ANIMATION ADDICT STORE as of May 14, this collection blends the series' dark atmosphere with vibrant colors.

Among the most striking pieces in the collection are acrylic keychains that reflect the supernatural and uncanny sides of the characters.
