On a separate note...
Having just now caught up on my backlog on this title, I can say with certainty that I'm glad that "Talt" is now "Tarte". "Talt" didn't come off as sounding like a proper name.
But now "Matcha" is "Maha"? Why? Because when you take "Tarte" into consideration, then it only makes sense that the author would keep up with the theme in names and use "Matcha", which is a popular green tea flavor for sweets like matcha cake. (Cake and Tartes. Get it? They're supposed to be Lugh's "deserts".)
