Aku no Meshitsukai

Aku no Meshitsukai, also known as The Servant of Evil, originated as a seminal Vocaloid song released by mothy, also known as Akuno-P, in 2008. It serves as a core entry in the Story of Evil series, a complex narrative project that utilizes the Vocaloid software to explore themes of power, tragedy, and consequence. The song's composition and lyrics were designed to provide a melancholic perspective on the life of a loyal servant to a cruel princess, intentionally evoking a sense of dramatic irony that resonated deeply with the early Vocaloid community.

The popularity of the song inspired an extensive multimedia expansion, including a dedicated light novel series authored by mothy himself. These volumes flesh out the lore established in the musical compositions, providing historical context and psychological depth to the characters. The design and presentation of the printed volumes, often featuring illustrations by artists such as Ichika, were created to match the gothic and baroque aesthetic established by the music, solidifying the series as a landmark work in the niche of fan-originated transmedia storytelling.
