The 25 chapters you just read is fan translated work.
11 volumes is the number of latest published volume in Japan. So, it's not translated yet.
so there isnt any official translations?
If you are referring to English translation, unfortunately no official translation at the moment.
sad, but isnt it kinda weird that theres dubbed anime episodes nad not even an official english translation?
Hmm.. It's actually common for a well-received anime to get English dub, but no manga release :)
Shounen manga from major publication is usually the only type that always have its manga officially published long before the anime even announced.
