Aun Freya, daughter of a village chief on Sandy Planet, frequently disrupts her community. Her impulsive actions include becoming infatuated with musician Laman and immediately departing for his hometown Peperon to declare her love, taking her village's revered sacred artifact, a waterproof marker. After disappointment with Laman, she promptly pursues the next handsome, wealthy man.

She wields Aho energy to generate stasis fields that immobilize targets. Paradoxically, she lacks immunity to her own power and can become trapped within these fields. Only Photon Earth remains unaffected by her stasis fields; he must physically disrupt the field by striking her head to free her. She resents relying on Photon for rescue and exploits his naivete to avoid returning to the village, sometimes using force. She often manipulates situations to her advantage by exploiting her brother's trust.

Her personality is erratic, wacky, and domineering, marked by a brash, authoritarian demeanor enabling control over figures like Papacharino Nanadan. She maintains a contentious relationship with Keyne Acqua, engaging in perpetual arguments primarily centered around Photon. She rejects the accidental marriage between Photon and Keyne, refusing to accept Photon as a suitable partner.

Aun frequently displays jealousy regarding physical appearance, particularly envious of Keyne's breast size. Both women are later astonished by Princess Lashara Moon's larger bust during a hot spring visit. She habitually denies any romantic association with Photon despite evidence of their complex interdependence.
