Nikki Hanada

Nikki Hanada is a modern-era survivor revived by the Tsukasa Empire after millennia of petrification, originally honed as a competitive judo practitioner. Initially deployed to covertly surveil Taiju and Yuzuriha on behalf of the Empire, her allegiance shifted dramatically when Senku promised to preserve the final recorded song of her beloved idol, Lillian. This heartfelt pledge was enough to bring Nikki firmly into the Science Kingdom's ranks. Combining raw physical prowess with an unyielding sense of justice, she voluntarily took on the role of self-appointed disciplinarian, keeping reckless members in line through sheer force when necessary. Her contributions span both operational management and frontline combat strength.
