The team responsible for scanning and translating are doing a lot of manga. If you go to their website you see all the other series they are also translating and scanning. As you see it is not easy for them to translate all the series they have picked up. The team are also in need of donates since it is difficult to fund them in order to continue what they are doing. They are also looking for other people who want to join their group and help them
Exactly because of this? I mean, most scanlators don't want to work in licensed titles.
I already saw a manga of vol. 6 at the store English subtitles.... why it's not still published in any manga sites?
