Rinon is an extraterrestrial being brought to Earth by Kazuka, disguised as an ordinary pet while secretly operating as the organic computing core of a spacecraft. Equipped with advanced capabilities including medical healing, spatial teleportation, and mechanical control—demonstrated when healing the injured Kaito—Rinon remained on Earth after Kazuka's departure.
