Wako is a member of the Midnight Flight drama club. She is one of the "Shrine Maidens" whose powers prevent Cybodies from being activated outside of Zero Time. Her powers and existence creates a seal, the Southern Maiden Seal, that guards the secrets of the island. As long as the seal is intact, she, a maiden, is forbidden from leaving the island. If the seal breaks, the Cybodies would be able to leave the island as well. Her grandmother was meant to tell her about being a Maiden when she entered middle school, but she apprivoised on her own when she was in elementary school, granting her access of all memories stored in the Cybody she was in. She once aspired to become a singer; as a child she wanted to go to Tokyo to seek that dream, but her status as a Maiden barred her from doing so. She has been engaged to Sugata due to his family tradition since childhood.
