These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: In the first 10 minutes it is established that Scythe Master used a combination of drugs and hypnosis to erase the main character's memories just because he wanted to test a new theory. He then leaves the main character to train for months in the Mojave desert with no contact from the outside world. This was the second experiment. The first person he experimented on he rapes, brainwashes, trains as a serial killer and treats like property, oh and the girl was twelve when he started this. A third person he experiments on he doesn't drug or rape, but he does basically lie to her about events, encourages her growing hatred and turns her full Yandere just to mess with the main character. Oh and while he is doing this with her, he is repeating his first experiment, six times over, just in case.
