Ok, so discussion for this chapter as a whole:
i understand that Canary dedicated small taskforces of S and A rank adventurers to the other 2 armies because both they are smaller armies, and more capable combatants overal, so i get why theres 6 people assisting in the manga (budget) and 10,000 in the books.
What i dont get is why Shirley is the Supreme Commander of the Beowulf Extermination Force, or how Canary knows about the limits of The Ambitions of the Lost Empire (The Katanas of Space and Time as ive mentioned). Yes Shirley needs to be there so the army can win, but i feel like Canary could have rented a Royal General and it would make more sense in this story.
