You had to have seen that joke coming. (If you’re not sure, that’s the Codec frequency Solid Snake uses to contact Otacon in Metal Gear Solid. Yeah, gamer joke.)

Episode 7 of Card Captor Sakura, “Sakura’s First Attempt as a Thief?!”, apart from being punctuated, deals mainly with Sakura and Tomoyo infiltrating an art gallery to, as usual, capture a card. There’s a lot of use of the word “kaitou” here, which is often translated to “phantom thief”. (Literally, the kanji are “strange/mysterious/suspicious” and “thief/robber”.) I would assume that this refers to the sort of gentleman thief who uses smarts and tricks and illusions to effect near-magical getaways, and which seem to be a fairly popular anime trope, on both sides of the protagonist/antagonist line.

The kaitou in Yoshinaga-sanchi no Gargoyle, Hyakushiki, states (whether he personally believes it or not) that the duty of thieves such as himself is to “liberate” various valuable items and put them “where they belong”. I suppose in this case, it kind of fits.
