Heheh, plenty of room. Sorry dude, I wasn't complaining about there being spoilers, those seemed pretty easy to avoid really, but thank you regardless. Meant to imply I was excited about joining the conversation once I had actually watched/simulwatched the show.
As always, good to have some Japanese language insight from our resident expert! Based on the doubling up, I'm glad they didn't go with FranXXBranXX or something...In the show, both the singular and the plural are "FranXX", so you get your wish, buddy!
Japanese plurals are quite different from ours in English. They're sometimes formed by doubling the word. For example, "person" is hito, and "people" is hitobito. There's a phonetic change there on what should be the second h; that's a typical quirk of linking words together in Japanese.
