When will the next vol be released??

Hopefully soon! I speak a bit of Japanese so I bought the raws on QPA, and Megumi and Tsugumi 6 is already finished, and it has been for a while. I'm pretty sure it's in the process of getting translated! The author uploads a new chapter for the 7th book on QPA as well, and it'll be turned into the complete 7th book (in Japanese) in November, and be translated after that :)
