Color pages in the back? Yup. We simply follow the Japanese editions. Nihei wanted them there, so we complied. What else should have done?
Regarding the length of Sidonia…Well, sure it is a concern. Length is always an issue even for hit titles. Honestly, I cannot predict the future so I don’t want to even speculate cause it might be misinterpreted as fact (which is something that happens a lot on the net these days).
