Mono would absolutely let her play with this one, though he truly didn’t realize yet how fragile they might be. He had only gotten it out of an odd, internal nagging that he should get one should Six ever arrive. Something to give her… But as yet, she hadn’t appeared and so he simply enjoyed it once in a while himself, when the odd sounds of the gray building when he was alone needed to be covered by something prettier.

The boy was glad that she seemed rather excited about making a game out of their practicing. Though his expression turned slightly serious as she asked about being eaten, it was a concern that Mono took rather seriously, after all. With the way his world was… It seemed like a valid fear to have. If anything, he wanted to make sure she stayed safe and this would make sure she didn’t have to worry about being eaten or hurt. “No, you won’t get eaten. I won’t let anything bad like that happen. This’ll make it even safer and harder for anyone to catch you if they try!” His quiet tone was stronger for a moment, sounding like both a promise and a reassurance.
