Ippan Seija no Conquista

Overview

Jitarou is summoned to another world as one of the heroes. He is given the cheat-level recovery skill "Heal," which can cure any serious injury or curse. Jitarou uses the skill "Heal" to remove the curse "Absolute Obedience Mark" that controls the hero as a tool of war, but his desperate situation remains unchanged. However, the goddess Astrea suddenly appears and saves him from his predicament, and he is ordered to restore the goddess's faith and save the heroes who were summoned with the guidance of the evil god. Thus, Jitarou becomes an apostle of God and sets out on a missionary journey... but for some reason, he is worshipped instead of the goddess!? (Source: Kadokawa, translated)
