"This is an ARMS band, it can hold just about anything I can pick up. The shop doesn't let everyone buy them anymore... but they're very handy! I let Devero store things in it, too."

"Isn't it neat? I originally just bought it so I wouldn't have to carry a backpack full of camping equipment on missions, since before I met Devero, I preferred to wander alone on them. But it's come in useful for a lot more than that."
