Father Owen shepherds a band of orphaned children through the chaos of a fractured, lawless Tokyo, reshaped by catastrophic earthquakes. Within the crumbling walls of a struggling parish, he partners with Sister Saeko to shield their vulnerable charges from the city’s rampant violence. His past as a hardened military colonel and mercenary surfaces in relentless clashes against the Koryukai syndicate, where he leverages tactical acumen and weapon proficiency to dismantle the gang’s operations. This journey from battlefield command to spiritual guardianship underscores a stark yet unexplained pivot from soldier to spiritual guardian, driven by an unspoken resolve to defend the dispossessed.
