The Holy Executioner

Forget peace and quiet. Sister Angelica is a nun who trades prayer beads for golden pistols, storming the gates of Hell with a manic grin and a heart full of divine fury. Armed with her signature "Requiem" Desert Eagles and an unwavering, violent faith, she has no time for stories or reasons—only the sacred duty to purge evil with relentless, merciless firepower. In her world, salvation comes not from forgiveness, but from a hail of bullets and a high combo counter. She is not here to save souls; she is here to end them.
