A book of hitogata would be extraordinarily rare (likely nobody has ever gotten one), very very expensive, and practically useless. There are only 2 drops in the game for it, Blueful Ultimate Indi Belra 1/22,003 (0.004545 %) and Viridia Ultimate Del Lily 1/28,289 (0.003535 %). It is not obtainable in black paper deal (despite what the quest drops page says, it just drops regular hitogata instead). Dancing Hitogata is also nothing more than a novelty, it takes several seconds for each extra card to appear, and when you attack it immediately sends all cards outwards in every direction, they cards cannot be launched at a single enemy and most likely won't even hit 2+ enemies unless you are purposefully getting surrounded. It would prob be expensive only because it's drop difficulty is on par with sjs, but has no practical use to make it actually worth buying. You'll prob have more luck trying to get one off the donation list for 25 (that is, if you have literally everything else and still have cash to burn) than try to trade for one.
