“Whoa! We talked about this! Why do you keep ending up in that bathing suit thing when you turn into a child?”
Flat hastily covered the girl in a nearby bed sheet.
“It just always happens,” Berserker replied. “I find being this girl kind of reassuring. I also end up wanting to dissect things, though, so I think it’s a bad idea.”
