A Goddess Candidate of Lastation and the little tsun to Noire’s big tsundere. Uni's a hard working girl who loves guns.

Like Nepgear, she was trapped in a sleep capsule for several years and now joins her friend’s quest to retake Planeptune.

Uni loves her sister, but Noire’s seemingly indifferent attitude to her return has left her feeling disillusioned and forgotten.

When she uses her Goddess Transformation, she becomes Black Sister.
