sidenote: Azumi Kagamihara from the #ZX series (both #ZXIgnition and #ZXCodeReunion) has one of the longer #Japanese surnames (at least in Romaji character count) that I've run into
but then we have Nadeshiko Kagamihara from #YuruCamp
that name takes the cake as the longest normal-sounding Japanese name (by "normal" I'm excluding such nonsense as that one meme where two characters have the same absurdly long name)
