"Hello! I have set up something called an arcade. It's less a series of puzzles and more like... challenging and hopefully fun games to play. And they give coins called eikos as prizes, which can be exchanged for magical items. So, any one of these that someone wants to play can get them whatever magical item they want, if they do it enough. Or they can vary it up. I've started moving into working on stuff that will help with practical skills, I'm working on an, er," they will probably not have the term 'shooting', "archery range thing, for practicing aim. Kose was trying out the one for reflexes against projectiles."
Kose has, in her frankly insanely impressive efforts, earned herself five eikos. This is enough to buy two communication pendants (2 each), or one set of either magic or night seeing glasses (5 each, but if she adds a 6th she can get customization options like different colors).
