Karneval - Koi ga Ai ni Kawaru Toki (Doujinshi)

This doujinshi, titled Karneval - Koi ga Ai ni Kawaru Toki, is a fan-created work centered on the popular manga and anime franchise Karneval, originally created by Touya Mikanagi. Doujinshi like this represent the long-standing tradition of Japanese fan culture, where creators produce independent, non-official publications to explore side stories, romantic pairings, or character studies that fall outside the narrative scope of the source material.

The volume was authored by the artist known as Ume. The work focuses on the established character dynamics of the Karneval series, aiming to deepen the emotional connection between characters through a stylized, expressive art format typical of the circle's aesthetic. Like many works in this niche, it was primarily distributed at events such as Comiket, serving as a medium for dedicated fans to engage with the series' lore through an alternative, artistic lens.
