Blood Stain Child is a Japanese metal band that merges melodic death metal with electronic music and features a notable rhythm influenced by European bands within the same genre. They were formed in the city of Osaka in 2000, and over the years, they've gained recognition for their unique blend of styles, often referred to as “melodeath” or “electro-metal,” and have also integrated elements of trance and Eurobeat into their sound. The band has seen some lineup changes since its inception, but they've maintained a consistent energy and approach to their music.

Their discography includes a progression from the early works like “Mystic Your Heart” and “Idolator,” which helped establish their presence in the metal scene, to the later albums “Mozaiq” and “Epsilon,” which pushed them further into a fusion of genres, cementing their distinct sound. With the releases of "TRANCE DEAD KINGDOM" and "gaia evolution," Blood Stain Child has continued to evolve, delving into more lyrical themes about humanity's future and existential musings, often reflected in their futuristic soundscapes. Their 2019 album "AMATERAS" and single "2045" outline their affinity for conceptual themes, often drawing inspiration from visions of the future and science fiction elements, alongside their powerful metal roots.
