[CENTER]Currently I have not found a better way to deal with manga and comic books.
I first download the manga/comic book (will refer to book from this point on) using Hakuneko
https://hakuneko.download now when I download the ebooks I go into the settings and change the download method from cbs to folder with images as HakuNeko downloads manga in chapters and not volumes after I download in folders I then go and sort them by volumes for manga and I just zip the comics up, once the books are sorted to the proper method and named properly I zip up the manga after the books are zipped up I change the .zip to .cbz (cbz is for zip and car is for rar) now I import to calibre and use the comic vine plugin to find the meta data now on my iPad I have a separate app for manga and comics so I don't convert them I just get the covers and metadata. for the ones using kindle convert them to azw3 and boom they work perfect you can also find very good manga using nyaa.si /CENTER]
