Photon the Idiot Adventures, 1 layer, A2, no sketch, no background, OVA
While Koro takes a shine to Photon, ultimately, it is Keyne’s computer pet. The creature is also the computer control system for her ship. A Koro is rare in the time of Photon, but in the OVA series Tenchi Muyo! The War on Genmar, they are plentiful.
