The scanlation of this great series has unfortunately been dead for the past half year, so that's a thing we're doing now. Just in time for the start of HXB 2 too! Chapter 60 marks the end of volume 10 and there are 8 more to go. The first 6 volumes are collected in two cheap-as-dirt omnibuses you may want to pick up instead of the 5-year-old scanlations on mangatraders et al.
