You already have a Koshi chime and do not know which one?
We can help.
Please take a look at your Koshi chime.
You will find the word Koshi on the side of the chime.
You can see that in the word Koshi, the letter O is filled with a color.
This color code tells you which Koshi you already have:
red = Fire / Koshi Ignis
blue = Water / Koshi Aqua
yellow = Air / Koshi Aria
green = Earth / Koshi Terra
