Chii

The main series character, the Persocom 'Chii". Chii is one of the custom made characters, Hideki found her in the trash, he liked her so he took her with him to his house.  Chii is also one of the cutest Persocoms! first she couldn't say anything, just saying "Chii", also she couldn't do any good thing, just doing the same what Hideki does. But then, Hideki could let her learn so quickly, and he lets her go out with her self [but of course, first he let someone go with her].
