Cha·pi is a cute spheroid with skinny legs and bold arms, plus a couple of cootie white wings. S/he's asexuated, and s/he's basically the mascotte of Hachiko. S/he lives along with him in the prefectur of Yokohama, Tokyô. S/he was carried away from his/her planet to Earth, thank to Unchiko's "Transfer Machine", along with his/her friend/master Hachi Inu Chin Irozu and the younger brother of the latter, Nyan Neko Chin Irozu. Like his/her master, Cha·pi is cute, and naïve. His/her fav. hobbies are talk and dance with his/her friends, read, and eat plastic or sily stuff (his/her fav. food are condomms [^^;;;;] and Kotaru's underwears, and sometime s/he eat 'em even when the latter is wearing them). S/he can turn into another thing : s/he can become whatever s/he wants, and s/he become the perfect clone of the person/thing s/he turned into. The only difference between the original and the fake is that, for the things, the copy speaks and got two cute dotties as eyes, and for the people, that the copy got a strange little voice and spells phrases bad. This skill often made Cha·pi to be abused by the various boys from the serie, but of course also by girls...^^;;;. However, when Cha·pi turns into a woman or a girl, s/he got a big gummy cock(^^;). It must also be noted, that s/he ends up all of his phrases with the honomatopeic "cya cya", and sometimes s/he make wordplays messing it up!
