Haikyu!! - Ore to Osananajimi no Shoya ni Matsuwaru Arekore (Doujinshi)

This work is a doujinshi, or self-published fan manga, centered on the characters from Haruichi Furudate’s popular volleyball series Haikyu!!. It was created by the artist known as Sum-Lie (Samula), an individual contributor within the Japanese dōjin circle community who produces unofficial stories expanding on the interpersonal dynamics of the series' cast. Like much of the content produced in this space, the volume was developed to explore specific character relationships outside of the original canon, catering to fans who engage with fan fiction as a primary mode of community participation.

The publication follows the tradition of Japanese independent manga, where fans translate their creative interpretations into small-run print formats. These works are typically distributed at specialized events like Comiket or through niche secondary markets like Mandarake or Toranoana. While the design and narrative direction are entirely independent of the official Haikyu!! production, they represent the vast secondary ecosystem of fan-led character studies that define the long-term cultural longevity of major shonen franchises.
