Tsubasa and HOLiC cross over at least once a volume, and if you're soley reading BWYS releases of HOLiC and Tsubasa, us releasing them timed together will make the story make more sense to you. But most people probably don't solely read BWYS releases. So, should we bother to keep this up?
Since there are less HOLiC chapters than Tsubasa, and the staff for HOLiC are more regular than Tsubasa, so we are usually actually up to date with Japan on HOLiC. However, we hold back HOLiC releases because chapter XX crosses over with chapter YY in Tsubasa, so that we can release them at the same time. Should we stop doing this and focus on catching up with Japan on HOLiC?
