Iczel Black, alias Nami Shiina, performs as a rock singer and rave dancer by night, seamlessly transforming into the Black Iczelion by merging with her specialized combat unit. Confident and decisive, she wields unmatched combat prowess among her peers, prioritizing efficiency in battle.

Her gravity-manipulating abilities anchor her combat style, paired with dual beam swords and an impervious defensive barrier renowned as her squad’s sturdiest. She excels in close-quarters combat, combining precision swordplay with audacious tactics, such as funneling her suit’s full energy into a single Gravity Slash—a devastating strike designed to pierce fortified armor.

When Geas forces invade, she strategically intervenes across dimensions, safeguarding civilians and fellow Iczelions with calculated maneuvers. Though she chastises allies for tactical missteps mid-conflict, her focus remains unyielding against adversaries like the Geas’s elite Voids.

Her background remains undisclosed in official media, with no details on her past before becoming an Iczelion or developments beyond the OVA events. The radio drama continuity connects earlier Iczer series narratives but does not expand her role or history.
