And I don't think Mary had any reason to associate Reisen with guns, Kilga :V

Okay, I'm probably overcomplicating things, but I have approached a possible dilemma regarding the ring situation.
1. Both Mary and Renko need one.
2. It would be best if those two matched, both visually and in use - the Ring of Rhythm is cute, but probably not nearly as useful as whatever Marisa makes (in general), and very unlikely to look similar.
3. There'd be a touch of romanticism to it if both of the set went unworn until presenting Renko hers as well.
Optimum solution I can see with that set of ideas in mind - get whatever Marisa makes today, but try to avoid using/wearing it unless an emergency comes up. If Marisa seemed to enjoy making it, try asking in a day or two if she'd be willing to make a matching one for Renko.
Problem being, of course, whether Marisa would still be friendly after the SDM invasion (ambiguous, perhaps somewhat unlikely) and that she might want Mary to try it out as soon as it's done to make sure it works.
... and of course explaining the need to visit Marisa for breakfast without giving away any of this. Though I guess saying that you'd/we'd like what Marisa made to be a surprise might be enough.
