Turns out Pencilgon did a lot of things off-screen:
- check out her loot
- equip Inventoria
- hide the other two in the Scale
- pass the Scale to Sunraku
All before walking out of the cave. It seems she was prepared to get rid of her PK status beforehand.
I have wondered what Psyger-100 meant by laundering in ep 19, and we got the explanation this time. (Still unsure how that would be relevant to a negotiation though.)
The Tomb of Truth Pencilgon got was the same as Sunraku's, so there wasn't additional lore.
How is hunting unique monsters a profitable enterprise? Pencilgon specifically said it in the monetary sense, but she spent a ton of mahni fighting Wethermon and hasn't got any back yet. Perhaps we'll see how she turns a profit in a future episode?
Wolfgang is a German male given name traditionally popular in Germany, Austria and Switzerland. The name is a combination of the Old High German words wolf, meaning "wolf", and gang, meaning "path", "journey", "travel". (Wikipedia)
This matches the kanji name 旅狼, travelling wolves, and also the title of this chapter revealed last episode: "Venturing Wolves, Be Ambitious."
