For the bilingual folks who are interested in completing your collection, I've posted a number of Spanish translations of manga volumes. They're all published by Grupo Editorial Vid, which for some reason is not in the PBS system so they don't have ISBNs and won't come up on your wishlist. You can see the complete list here or by just going to my shelf and filtering it for "Comics & Graphic Novels."

These can also be combined with other books on my shelf at 3 books for 2 credits; PM if interested in doing that.
