Original sentence: ADV's translation notes do (in order to note the original Japanese version of a particular joke, which hinged on knowing the honorific's meaning) mention that it is a type of affectionate, cutesy affixation for the end of names, though they do not refer to "rin" as an honorific.In ADV's translations, however, they use "Kaorin" rather than "Kao-rin", the latter being a more traditional way to denote an honorific.Kaorin's surname is speculated to be Aida, judging from a panel in volume one of the manga, however this is still unconfirmed.This takes the first part of her name, "Kao", and adds the cutesy honorific "rin" to it ("rin" is a cute form of the "chan" honorific and is used in many anime/manga titles)
Edited sentence: Because of ADV's policy to not use any honorifics in the subtitles save for "chan," they attempt to hide the fact that this is an honorific by using "Kaorin" rather than "Kao-rin.Kaorin's surname is speculated to be Aida, judging from a panel in volume one of the manga.This takes the first part of her name "Kao" and adds the cutesy honorific "rin" to it ("rin" is a cute form of the "chan" honorific and is used in many anime/manga titles)
