A compilation of differents artist's works on the Devilman universe. These stories are not canon nor important to the series, so you can read them whenever you want (of course, first having read the original Devilman).
Most of the little stories presented in this compilation are either unintelligible, boring or down right bad.
While this is a fast read (only 18 chapters) I would only reccommend this to Devilman Fanatics, and even for them this one should be hard to swallow. Bored me to death, maybe only 2 or 3 stories were interesting. There's also a few stories made by Nagai Go (the original creator of Devilman) so you might want to read them, they're not that great but they were made by the man himself, so... overall, unless you're a hardcore fan, avoid this. Truly a waste of time.
