Olivia's God Hand

Olivia, a descendant of the protective clan, is attacked by demons.
Gene saves her, but loses his own arm in the process.
Olivia implants God Hand's divine arm into Gene, making him the new wielder of that power.
They unite to confront evil and prevent the return of Angra, which is orchestrated by the "Four Devas". After that day, Gene and Olivia decide to stay in a hotel in the middle of the city. In a fantasy setting, Gene is with the Hand of God, which Olivia... Although she carries an axe (which she mainly uses to encourage, or sometimes threaten, Gene to fight), she has little combat skill and is frequently kidnapped by the villains, serving as a plot device that motivates Gene to move forward. Olivia always taunts Gene with her axe, trying to get Gene to fight.

The story begins when Gene, a drifter, tries to save a woman named Olivia from a group of bandits who are actually demons in disguise. During the confrontation, Gene loses his right arm. In a desperate act to save him, Olivia (who is a descendant of the protector clan) bestows upon him the legendary "Arm of God" that was in her possession. With this power, Gene easily defeats the attackers.
After receiving the divine arm, Gene and Olivia travel through a desolate land, facing hordes of demons and other bizarre beings. The main objective is to prevent Angra and his generals (including Elvis, Shannon, and Azel, who possesses the "Devil's Arm") from fully awakening and dominating the world. Olivia's appearance: Olivia is a 19-year-old girl with short red hair. She is most often seen wearing a light blue minidress and a darker blue short-sleeved jacket, a brown belt, and brown knee-high boots. Olivia's eyes in the game God Hand are green.
