Archer, Assassin, and RP Saber, being Servants, have a backup translator doohickey through Holy Grail summoning BS.
But if those also failed, Archer would default to Japanese (but know English, somewhat), Saber would default to Old English (which is what FG Arturia would also speak), and Assassin would speak a language that I will not disclose because that would provide a hint to her country of origin, and thus her True Name.
Miyu would alternate between Japanese and German.
Clarice would speak English, but be somewhat fluent in Japanese.
Sibyl is a natural-learned omniglot.
Takanuva would be speaking straight-up Matoran.
Gilles would be French as fuck.

Jack would speak some kind of 51st Century variant of English, I'd say. I have no idea what that would look or sound like.
What if there’s no better word than just not saying anything?they were not set in japan, they were set somewhere based in japan
then unova was based in america, and it was shit
then kalos was based in europe, and it was good
coincidence?

"I like girls, but now, it's about justice."Leo would probably be speaking a more Germanic form of English that would probably have a lot of Gaelic and Celtic influence. There wouldn't be too much Latin in it, but he'd certainly know Latin.
Though by this point his accent is not at all a regional kind. He'd also be fluent in Irish.
1.5 imperial gallons of tea were consumed during the writing of this postayyy
del, claire, and the twins would be speaking this odd version of english where
it kinda sounds like english but like kinda italian at the same time
there's a reason for that but im tired so piss off
both vonkats are speaking a mix of serbian and russian
I live in a constant state of fear and misery.

Shit, I should totally work this into a plot somehow
Everyone, forget I said anything so I can do it later and you can all be surprised.
Unless someone else does it first in which case I will be the one who is surprised.
