Shoka is a vampire hunter operating within the Vampire Hunters' Guild as part of Ronaldo's professional network. He combats vampires using specialized equipment adapted from his former career as a firefighter, primarily wielding high-pressure water streams as weaponry.

He maintains an unbreakable partnership with fellow hunter Medoki, a professional relationship formed unconsciously due to Medoki's helpful and caring nature. Their shared age further reinforces their effective collaboration.

Shoka transitioned to vampire hunting after developing a strong interest in vampire hunter films, leaving behind his previous work as a firefighter.

Within the guild structure, Shoka operates alongside numerous other hunters, including Satetsu, Shot, Maria, Ta Chan, and Homerun Batter. The guild operates under Master (Gōsetsu), who assigns hunting jobs from his bar establishment.

One noted personal characteristic is his preference regarding physical attributes, specifically that he considers hiplines essential standards for women.
