Part One
Head to Norg and as a Samurai, talk to Jaucribaix (K-8) who will mention that a sacred ritual to guide the lost spirits of the dead is needed, but that he's missing a feather from a special bird, found only in the Labyrinth of Onzozo.
Speak with Washu at (J-8) who will tell you to bring her a piece of Giant Sheep Meat, a Frost Turnip, a Bastore Sardine, and a Hecteyes Eye if you want the KeyItemWashu's Tasty Wurst that is needed to lure the bird out.
After obtaining KeyItemWashu's Tasty Wurst, head to Buburimu Peninsula and enter the Labyrinth of Onzozo.
Stick to the left wall all the way until you see a hut with a ??? at (F-8).
Click the ??? and choose to lay down the KeyItemWashu's Tasty Wurst to spawn a Notorious Monster Roc, Ubume.
Be prepared for AoE Sleep from Horde Lullaby about every 30 seconds.
Ubume can be silenced.
You do not need to have Samurai as your main job to kill Ubume
Defeat Ubume and re-examine the ??? to obtain the KeyItemYomotsu Feather.
Return to Norg with the feather and speak with Jaucribaix (Samurai as main job not needed).
Part Two
Exit and re-enter Norg and speak with Jaucribaix again, and he will say that he has finally forged the katana, which he named the Yomotsu Hirasaka.

part1 i was finished it
Exit and re-enter Norg and speak with Jaucribaix again
“do not rush me! this job requires extreme concentration. think of the consequences if i were to hurry through my work! ” Jaucribaix has been repeating this sentence.
here I would like to ask my friend, how can I do, how to save themselves?
