I'm still a bit torn on L'arc.
(Or "La•ru•cu," since we cannot leave out even the most obviously unnecessary Hiragana vowel sounds when translating into Romaji, it seems...)
I know the obsession with the name L'arc comes from "l'arc en ciel," and I can respect that it looks cool; I loved the name "D'arcy," just because it had an apostrophe in it.
I get it, and I do NOT think ill of it.
K?
That said, every single time I read a Main Character with the name "L'arc," my brain farts with laughter about their name being "Rainbow."
