I had to check the raws and there's only one thing to mention:
update: ch14 realeased by rycolaa - check the artwork in the beginning where they are cleaning the pool : 2 new characters coming?
just on a side note: This mangaka, Miki Yoshikawa, was the apprentice of Hiro Mashima, creator of RAVE and Fairy Tail therefor the resemblance in the drawings. Now according to ch13-news on rycolaa YTM currently is Hiro Mashimas favorite manga.
