Some might disagree that this is a complete set, as it doesn't include the comic version. Also, based on my personal opinion, it's too difficult to connect Genma Taisen DNA with Wolf Guy, so I consider it part of the Genma Taisen series. One book has graffiti on the cover. Otherwise, the first series of NON books shows some sun-fading on the spines due to age, but there's no significant damage, and they are in good condition.
