Cat Planet Cuties
Cat Planet Cuties is a twelve episode (plus OVA) anime series based on the Japanese light novel series Asobi ni Iku yo! (あそびにいくヨ!?, lit. "Let's Go Play!") by Okina Kamino with illustrations by Hōden Eizō and Nishieda. The series is of furry interest because of the amount of Kemonomimi characters.
Human protagonist Kio Kakazu is attending a memorial service for his ancestors when he encounters a girl with cat ears and tail named Eris who claims she's a Catian, a felinealien race. She is soon targeted by various agencies, and Kio finds himself protecting her from harm. Two of Kio's friends, Manami Kinjou and Aoi Futaba, turn out to be operatives for two of the agencies. Kio's home is soon designated as the provisional embassy for the Catian race, and Manami and Aoi become its security force.
