Well I choose my username because it was supposed to mean blue cat in japanese.
Blue because it's my favourite colour and cats because they're kawaii and the name for them awesome in japanese.
I choose to write it in japanese because i learn it as a language and the have a great pop culture but I asked my sister what blue was in japanese(hadn't learnt it yet) and she said it was ao.
I later learnt that it was aoi by reading manga(LOL) but it dosen't really bother me because it just means it's more individual plus it has a better ring to it.
