for rank 5? sorta.
it only took a few hours for me, a silly 23 rdm, a 60 drk, and a 42 whm to do it.
You have to goto all 3 places, sign up for tenshodo, get quests, do quests, wait for some nm, navigate through the 60ish mobs areas, its difficult but not too hard, just takes patience really. The best thing to have is sneak and invisible. without that it will take plenty of 50-60+ people and more time.
