Party Finder
Log into Masamune during Prime hours and you will find roughly 30 parties in the PF looking for members.
"But Mysha thats a great thing! your server is alive and running content"
Only if your client is in Japanese or your skills at typing in Japanese appear to be native, 70% of the parties in PF have "JP Only" in their comment section, yes even for brayflox speed runs, if you join one, god forbid you do, and the leader searches your information you will either get an instant kick (due to Client language being E ) or later in the run itself you will be booted for harassment/afk

Duty Finder
Duty finder is basically the same as PF, just the other day i tried to help a friend do levi extreme only to get booted from the group because i said the word "黒魔道士"[BlackMage] (Jp players shorten it to the word "黒", Fail on my part)
