Pretty sure Yuya and Ruri had the most chill introduction out of all the counterparts.
It seriously went like this:
“HI, I’m Yuya”
“Now lets get out of here”
“Sure thing person I just met”
Ok not really but it was probably the quickest first meeting with little amount of drama, before the parasite factor, I’ve yet to see.
I was impressed how quick they were to get with the program. I’m sure if that doctor wasn’t around Ruri would have aligned with the Lancers quicker than Serena did.
If you check under the cut, I have a bunch of examples of counterparts meeting for the first time.
