Hikari, the First Queen, stands as the primary antagonist in the second season narrative. She asserts herself as the true Queen of the Universe and wields power sufficient to annihilate planets, posing a grave threat to the galactic order. Historically, her reign marked an age of fear, embodying the archetype of a malevolent ruler.

Her background involves imprisonment and expulsion by the royal family, fueling deep resentment and driving her quest to reclaim the throne. This quest centers on gathering three sacred royal regalia: the sword, mirror, and bead, essential for legitimizing her rule yet deviating from traditional interpretations of these objects.

Hikari employs direct body possession, notably taking control of Mutsuki's form midway through the story. She also utilizes brainwashing techniques, transforming individuals into loyal minions via physical kisses or blown kisses. This ability affects key figures like Mitsukuni and members of La Résistance.

Narratively framed as a physical god-like entity, Hikari possesses the capacity to create and destroy worlds, impacting significant portions of the universe. Her ultimate defeat results in the dissolution of the galactic monarchy, paving the way for a democratic system.
