Kio Kakazu is at a memorial service for a family ancestor when a girl with cat ears appears out of nowhere and introduces herself as Eris, an alien from a planet he's never heard of. She moves in without much explanation, and this ordinary teenager living in Okinawa suddenly finds his routine upended by an extraterrestrial roommate with feline instincts and zero grasp of human boundaries. This manga adapts the Asobi ni Iku yo! light novels, released overseas as Cat Planet Cuties.
