it's also a bit of a relic of an earlier version of the story, from what utsumi's said (that he was originally going to be stranded in japan alone and trying to earn money to move back to canada), but it's interesting that part of what drives langa into the S community is being Othered in this way

there's really no way to translate it but langa doing the nookling speech quirk and repeating just the last couple syllables of what reki says (particularly when he's asking someone a favor or thanking them) is so moe
