Towa and Mira are key figures in Bardock's narrative. Towa augments Bardock's power through scientific modification, turning him into the Masked Saiyan. She also harnesses energy from Bardock to empower Mira. Mira participates in battles and gains strength from Towa's energy. Their shared objective is to merge the Demon Realm with the Universe, forming Towa's envisioned 'garden of evil'.
