Okay, to explain Doriri. Dororo craves attention and doesn't get it, but Doriri gets attention she really doesn't want. Also, she wears her mask not because she's afraid of germs, but because it helps her to blend in with the background, because it's the same color as the walls of their building.
At Around The Same Time… Elsewhere
"Gertrude! Put down the sword! It's just me!" Kerora exclaimed, startled by the lethal weapon aimed at her face. Gertrude sighed with a mixture of relief and annoyance, putting down the half-sharpened sword she had been sharpening.
"What do you want, Kerora?" Gertrude asked irritably, not really caring. Kerora, although relatively efficient, was most definitely not Gertrude's favorite person. She had a tendency of getting on Gertrude's nerves.
"Just came to tell you that you need to pack," Kerora said defensively, noting the irritation evident in Gertrude's voice. "We leave for Pekopon tomorrow."
"Heh. They finally realized the ARMPIT Platoon is useless, eh?" Gertrude chuckled, shaking her head. She'd never seen any pictures of their predecessors, but she's heard some things. Their weapons expert had fallen in love! The idiot…
"Yeah, I guess," Kerora said, shrugging. "Speaking of the ARMPIT Platoon, I wonder why the five of us seem to be the only ones who don't know what they look like." Gertrude nodded thoughtfully. She'd always thought it was strange.
"Maybe they're intimidating and they don't want us scared, or they look stupid and they don't want us getting overconfident, or…" Gertrude said, trailing off. Kerora sighed. Maybe it was for no reason at all, but the way the military guarded their secrets, they might not know until they were face-to-face. She hoped that they wouldn't get violent when they learned that the girls were taking over.
"Well, anyway, Gertrude, you should start packing," Kerora said, and ran off to finally start the packing of her own.
