Re: So I'm curious...
Most of mine are really, really dull, just direct lifts from canon (winter_sleep is the name of a Trapnest song, littlespring is the (ironic in context) translation of Risa's name, firstchildren is Rei's title in NERV, odetojoy is a major arc song in the anime and appears in the manga), but I went for a different tactic this time because... well, I couldn't find anything catchy enough in canon for Nakama.
I chose agoodfamily because that's really what her whole arc is about - what constitutes a good family? Who's got the better "family" - the girl who ostensibly has both parents, stably employed, but is filled with messages of hatred and bigotry and the value of publicly belittling and ostracising those you don't agree with by her mother? Or the one whose mother is a prostitute, who has no idea who her father is, but is filled with messages of self-reliance and acceptance and seeing the best in people? It sounds a bit trite when boiled down to something so simple, but the manga asks the question really well, and doesn't get heavy-handed with its version of the answer.
