I've not seen any of these translated since I scanned 1 and 4 a year or so ago so figured I'd do some, so here's the bonus manga that came with volume 1 of the BDs, I'll do the others as and when. Excuse the slightly shitty scans and typestting etc, translation is the only part of manga scanlation I've got any experience in at all.
