Uberich: Advent Sinners is an ambitious visual novel that combines an enormous, vividly realized world with cinematic battle sequences and a layered mystery. The story kicks off when Joe and his ex-girlfriend Raina are rescued by the Hartson sisters after a violent alley attack, only to be drawn into a deeper conspiracy involving shadowy assailants, secret labs, religious conflict, and a spacefaring blockade. What begins as a small, intimate incident soon unravels into a globe‑-and even cosmos‑spanning narrative.
