I don’t think there’s been a thread like this. It’s a simple one, I’ve seen plenty of unique usernames on this site, probably not originating from Gundam, and if you feel like sharing your story on that, please do.
The “shin” in my name comes from my eventual selection of a name in a 16-bit RPG, that only allowed 4 characters to be selected for a character name. “star” comes from my love for science fiction, and “lord” is a homage to a strong mage, also in an RPG.
I suppose even if your username is about Gundam, then you should share it to. It doesn’t matter if it’s crazy unique
