Kuroshinri Kanojo ga Oshieru Kindan no Shinrijutsu (2021)

"I only ever notice it after-the-fact... but it's always what she wanted in the first place!" Ever get that feeling?

The forbidden technique of "Dark Shinri-Jutsu" (aka "Dark Psychology") is a method of using casual conversation, hints, words and behaviour to manipulate the thoughts and emotions of others to control them as you wish whether that be to good and innocent ends or to satisfy even the darkest desires of the heart.
