Jujuku "Juju" Shunamur (also romanized Shunamul) hails from a hometown where she served in a religious role, wielding a portable altar as her primary mystical implement. This altar served both as her spellcasting focus and a scrying tool for long-distance targeting. She left her community following a specific event: a statue of another town's mayor fell from the sky and danced uncontrollably, leading her church and townspeople to venerate it as divine. Disillusioned, she abandoned her home to join Nike and Kukuri on their journey.

Juju exhibits a contrasting duality in temperament. She typically presents a gentle demeanor that abruptly shifts when using her powers against adversaries, revealing a more forceful and intense side. This earned her the description of embodying "Cute and Psycho" traits in combat. Her capabilities firmly establish her as formidable despite her appearance; she once effortlessly incapacitated three guards holding her captive in a tower. This prompted Kukuri to question the logic of a hostage overpowering captors, while Nike noted its effect on their perceived role.

Her combat style involves improbable applications of the portable altar. Beyond spellcasting and observation, she manifests a sword composed entirely of water, indicating hydrokinetic manipulation. She also employs divine petitions to summon lightning strikes against opponents, merging her spiritual background with offensive power. Her approach to conflict is direct and decisive, often opting for confrontational resolution.

A notable behavioral trait involves engaging in non sequitur writing during inactivity or boredom. She habitually inscribes arbitrary or disconnected phrases onto sheets of paper without apparent context to ongoing events, representing a distinct facet of her personality outside combat or mystical contexts.
