I managed to pull off a 189-hit combo completely by accident with Yuri, I actually had no idea how I did it at the time but looking at the post above I guess it was because the Tension skills activated (I actually had not read carefully what they did
). I just started pretty much spamming my artes with reckless abandon and that's what I ended up with, didn't even use a Burst or Mystic. My skill and arte setups were pretty much the same as the post above though, so yeah, I can also vouch that this definitely works.
