Specific once c*ually be found in

1) Fuku (sometimes)

2) Treasure of Sage

3) Super Cheap Shopping (i ve seen some scrolls in the past few days in this event).

But getting the specific ones...for black tiger, the deer or the monkey, it will cost you several thousand cps / ingots.

There are no katsuya contract scrolls imo.

You must mix this up with her Mystery Stones.
