Starting with the second Zerozaki novel, each book in the series came with six cards from a fake/parody collectible card game.
Each card has an affiliation in the upper right hand corner; three stats (Life in green, Attack in red, and Defense in Blue); and a unique trait.
These cards did get shuffled once, but I think I've got them matched to the novel they came with.
Zerozaki Kishishiki's Human Knock
Zerozaki Hitoshiki
Psycho
"Migiwame Toshiki"
One turn in three: Unable to attack.
[This particular card and novel feature a young Hitoshiki, one still using his original name from before he 'awakened' and joined the Zerozaki family.]
Zerozaki Kishishiki
Psycho
"Folly's Praise."
If there are cards placed on both sides, attack is halved.
[Zerozaki characters often share a nickname with their signature weapon, and these nicknames are a translator's nightmare; the kanji and the rubi being unrelated. For example, the kanji here are a reference to In Praise of Folly, but the rubi are katakana -- a cryptic English nickname. In this case, Seamless Bias. (Probably.) The cards, fortunately, do not have any rubi, so I don't have to deal with this here.]
Zerozaki Soushiki
Psycho
"Suicidal Tendencies"
If the card being fought is female or a boy, all stats are tripled.
[Since I just did the research, I did find a Japanese reader's theory that Soushiki's alternate nickname is a reference to German philosopher Philipp Mainländer.]
