The story centers around Kio Kakazu , a high school freshman living in Okinawa. During a memorial service for one of his family ancestors. A mysterious girl with cat ears appears before him indroducing herself as Eris and claiming that she is an alien. However She be more troubling than he first realizes.
there's a lot of cute characters here. the animation is excellent and the story is quite simple but if you like fanservice this will really satisfy your cravings. i'm specially interested in the assistaroids and their individual abilities too bad their is only a handful of them. the weapons are also quite interesting however, due to this there is lack in the action department, but the humor and ecchi factor is just enough to make this anime a real fun to watch.
