You probably all know about the Best Wishes beta art, but by looking at it closely, I have attempted to decypher and translate the name of the Mijumaru evolution.....
Here it is circled:
Now with the characters matched up with the characters they resemble the most
ラコノスア
Rakonosua
As you can see, I have decyphered the Mijumaru evolutions name as "Rakonosua", it may be wrong though, but I did the best I could to translate it.....
I will probably do the Tsutaja evolution later.....
