[Spoilers] Which branch to choose?

You were never much of a waiting person Generally ends up with Kantor becoming submissive to Marty - willingly or unwillingly.
Wait for a right moment to attack Is the dominant Kantor branch in which she enslaves Monika and then tries to conquer the world. Also, turns into a futa. Currently on hiatus, but next in line to revive :)
Wait for a better opportunity - Same as "A man". Currently on hiatus with no plans to continue in a near future.
