Random question but how the hell do you come up with the name "Matcha Green Tea" for your oc???
To make a long answer short; Matcha is an Herbkin, a species based on the "vegetable lamb of tartary" cryptid.
The basic gist of Herbkin is that each of them is based off of a different Herb/plant that can be brewed into tea and their naming convention is based off of the type of tea they are.
Matcha is named "Matcha Green Tea" because that's their flavor/type of tea!
Here are some examples of more herbkin with this naming convention (they are all different types of green tea):
