It happened – at the beginning of the 21st century, finally, brothers of intellect arrived to us! Only the message that their elusive ships transmitted put Earth"s brightest minds in a deadlock, because it was very simple: "Let"s play!" While the powerful searched for hidden meaning in those words, and scientists checked the correctness of the decoding, on sunny Okinawa a 16‑year‑old Kio Kakazu one fine summer morning found in his bed an attractive girl with cat ears and a tail. Eris, as the guest introduced herself, was an envoy from the distant planet Kyatia, who had come for cultural exchange and to establish e‑e… personal contacts. Oh, that"s how they do it! Unexpectedly, the poor boy"s house turned into an alien embassy, and the boy himself, living without parents, became a reluctant diplomat. Naturally, serious organizations did not view the first contact so lightly and hurried to correct the situation. In the end, the main character, whose name by the way means "wonderful world," quickly realized that the real world is organized much more complexly. A cheerful childhood friend suddenly turned out to be a rookie CIA agent, a strict teacher – a member of a secret order, and the modest girl in glasses, with whom Kio felt a kinship, was actually a contract killer with an international reputation. In short, life became more fun, but you can"t strike in the mud – we need cat‑girls!
