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: Nyan Koi!
Woolseyism: Before the series was licensed, the subbing groups worked in their own functional Wooseysism. The small Show Within a Show at the end of every episode, Nyankoma ("nyan" being the Japanese onomatopoeia for "meow," and "koma" being a kind of comic strip), is Woolseyed into "Mew View."
Otaku USA (a magazine) notes that Kanako calls Junpei "Kou-sucka" which pretty much fits actually with "Kou-baka". Almost has the same insult meaning.
