Erio Touwa

Erio Touwa is the mysterious cousin of Makoto Niwa in Ground Control to Psychoelectric Girl. After disappearing for six months, she returns wrapped in a futon and claims to be an alien.

Erio Touwa behind the alien claim

Dreamy, withdrawn, and socially vulnerable, Erio uses the alien story to avoid confronting trauma and missing memories. Makoto's refusal to indulge or abandon her helps her return to ordinary life.

Memory loss, social recovery, and her bond with Makoto

Erio has no confirmed extraterrestrial powers; her significance comes from unreliable belief, emotional recovery, and the show's uncertain supernatural atmosphere. Her relationship with Makoto and mother Meme gradually reconnects her with school, work, and other people.
