["Missing an arm" seems like a drastic comparison to make though Naoto shouldn't be surprised. She herself feels naked without her gun, and she's spent the months she couldn't summon her Persona feeling like there's a hole in her head. She still feels that way in some manner, when she still cant summon him the way she's gotten accustomed to in the Midnight Channel. If Yamato Takeru were to disappear from her mind completely, Naoto has no doubt she would be feeling worse than carrying a hole in her head.

So in a way, Naoto thinks, she doesn't fault the boy for his comparison.]

I believe I understand. [She shifts her weight from one foot to the other, crossing her arms over her chest.]

If you don't mind me saying... [How to word this?] I'm not sure there would be battles any time soon for such support to be needed. Though I wont fault you for preferring to keep it close.

[Says the human with her gun holster still visible.]
