comment #27118 I have yet to meet someone that actually watched the show, because they say about 100 times in there "Only the person she loves can touch her there." Meaning its an on only switch, flipout if its not her lover switch, and have sex with if it is her lover switch.
I never saw the end of the anime, but I know the "switch" stuff is in the manga. At the end, Hideki is all "I love her, so I'll stay with her even if we can't have sex," and the woman who created Chii is all happy with that. I imagined an extended ending where it's a week later and the woman who made Chii sees her and she's back to just saying "chii" instead of all the words she learned. Hideki just has a sorta sheepish grin on his face and he shrugs at the woman. THEN the story ends.
