Formed in 2008 in Helsinki by guitarists Anton Kabanen and Juuso Soino and drummer Pyry Vikki, the project is the follow-up to 2013's self-titled album.

Kabanen sees Unholy Savior as a step forward for himself and the group, and he says the album's theme continues his fascination with manga series Berserk.

He says: "I thirst to go further as a human being and the music on this album represents a part of the ongoing spiritual journey - that's what I tend to I call it - which is my road onward. Music-wise the songs have been expanded to a wider area as an effort to call out emotions close to those I myself had during the times of birth of these songs."
