Above is the word "tomodachi", which means friends and by each girl is their own name in Japanese.
I used Google translation because I was a bit off in trying to figure out how to write each one's name.
I think the two have an interesting friendship, and I.m especially glad neither girl is dumb while the other is completely smart; that's a cliche.
