While details are light, the first volume will see its release in Japan 04 April 2016 for ¥400 + tax.
AnimeLand had initially reported this information 14 January 2016, though no concrete source was provided beyond a note about Shueisha’s plans for booksellers.
The ninth chapter of the Dragon Ball Super manga adaptation will see its release in the April 2016 issue of V-Jump this weekend in Japan. By the collected volume’s release in April, one more chapter will have been serialized in V-Jump. Beyond this normal serialization, a two-page bonus chapter was published within the Jump Victory Carnival 2015 event’s official guide book.
In comparison, Dragon Ball SD collected volumes tend to contain ten chapters plus any relevant or timely bonus material. This appears to line up well with the amount of Toyotarō’s Dragon Ball Super material at this point in time.
