hiya folks! hopefully this is the right category to post this in.
I’ve been playing the video game Xenoblade Chronicles 2 lately (it’s a lot of fun!) using Japanese audio and English subtitles. however, quite annoyingly, not all of the audio is translated - only the main cutscene stuff is, leaving a lot of interstitial dialogue making little to no sense to me. I can still only pick up on certain words or phrases 
I’m curious about a certain line that one of the characters says when you have them do a specific action in the game. to me, it sounds like:
“mutaimeiwa!
runrunhatarun
de iko ne”
or maybe, " むたいめいわ！るんるんはたるん。で、いこね！"
for context, the character says this when you send them off on what’s called a “mercenary mission” - they say it regardless of whether they’re going alone or with a small team of people.
I really have no idea how close or far off I might be on that transcription, but I’d love to find out what this could possibly mean. thanks!
