Shoka serves as a vampire hunter for the Vampire Hunters' Guild, adopting a firefighting motif in his operations. He wields high-pressure water streams as his main weapon during confrontations with vampires. His standard partner is Medoki, a fellow guild member. Their collaboration formed naturally over time, influenced by Medoki's inherently supportive and attentive disposition and their common age group. Before joining the guild, Shoka pursued firefighting as a profession. His fascination with vampire hunter films sparked his career shift away from firefighting.
