These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: A.I. Love You
Creator's Pet: Cindy. Akamatsu says as much in that volume's interviews, and visually, she's even more of a proto-Naru than Saati is.
The Scrappy: Forty. Does he/she have any sense of reason? (This childishness gets worse over the course of the series, even visually — toward the end, the female Forty looks about six years old.)
