Monster / Visual Novels

"You will watch and you will learn what happens when I am displeased!"

"Sakuma was a monster who gained the power of mind control and enjoyed it to the fullest. He only played at being a good doctor. Sakuma once saw me using packing tapes to treat an injury and laughed. 'Not bad,' he said. I didn't know what he meant. Do you remember the second murder? When Takayanagi, the street musician, was killed? Her stomach was cut open and a speaker was put inside. She was mind-controlled into using packing tape to stop the bleeding. When I saw him make her use her packing tape, I asked him why he was making her do that. And this is what he said. 'She's just like you, right? A doll. Isn't that funny?'... He's not normal. They talk about people who get pleasure from killing, but he's not even that. All he cares about is whether or not he finds something entertaining... and it doesn't have to be murder."

— Serika Onoe explaining to Takuru Miyashiro the true nature of the latter's adoptive father Wataru Sakuma, Chaos;Child (SciADV Series)

In Sasami's route, he goes as far as to attempt to rape her, and in the bad endings of both routes, he would succeed and begin forcing the women under him through "inspection". Sleazy and despicable, Oda is a chilling reflection of how horrible a human being can be in the idol industry.
  • Haruka Enokida is an idol who will do whatever dirty deed to get to the top. Cruel and sadistic, Haruka wears the mask of a sweet girl before striking. Luring other girls into her posse, she uses them to bully and humiliate her competition to permanently scare them from the industry, like stripping Mariya naked with scissors and suffocating her with a bag of feces when she was in Quasar or belittling Kana into a mental breakdown. At Aki's and Sasami's route, she shows the full extent of cruelty by attempting to run over Kamijou after her sex scandal was exposed and was fired in Aki's route, and in Sasami's route she assists Kenjiro Oda in his hostile takeover of Quasar. While letting Oda assault Sasami, Haruka goes on to rape her two group mates, Kaori and Stella, cutting them, taking snuff photos and brutally violating them with a dildo, and using it as blackmail to force them to leave the industry, with the intent of doing this to future competitors. Ruthless to the core, Haruka will stop at nothing, even rape and murder, to be the top idol.

After Masamune realizes that Mary was responsible, she explains her sadistic lust and transforms into a horrific monster before trying to kill him.

For no reason other than their own amusement, they attempt to instigate a war between the bull and lizard tribes by kidnapping their children and framing the other for it, and depending upon Eyvind's actions, one of their villages can be wiped out and everyone in it killed. When Thane manages to track the kids down, the chameleon will attack and nearly kill him, and should Eyvind retrace his footsteps, he'll hear their cries and find them all in cages, with one skin and bones and barely hanging on. The chameleon will then approach Eyvind, disguised as Thane, to get Eyvind to drop their guard to attack him when his back is turned, at which point they'll reveal their true self and sadistically tell Eyvind that once they've killed him, they're going to do the same to all his friends while wearing his face. If he should lose to them in the ensuing battle, the chameleon will rape him, then use their blood to painfully twist his bones and contort his body into a different form before cutting out his tongue. Then, out of pure sadism, after disguising themself as him, they will kill Eyvind in front of his friends, having fooled them into believing he's a monster.
• Tokyo Dark has these two men who are responsible for warping Reina/"Ruby" into the twisted spirit she is in the game:
  • Eiichi Higashi, as the president of the sketchy talent agency Omega, had numerous young girls taken from the streets to be pimped out, sold, and exploited by himself and his clients. One of these girls was Reina, who had an innate talent as singer, and good looks, which he abused by trying to manipulate her and force her to do dirty deeds for potential associates. Whenever Reina resisted or had an emotional breakdown, Higashi would worsen his abuse, yelling and beating her down. This eventually drove Reina to suicide, which he tried to take advantage of for publicity. By the time Reina's spirit came back and killed him, Higashi had done this to dozens of other girls.
  • Shinji "Tokimassa" Umezawa was the leader of the second Kamenkai cult. A madman who despised humanity for their sins, Tokimassa created the Kamenkai cult in the Suicide Forest and indoctrinated Reina and her family into it. Seeking to reach the land of the gods, Tokimassa eventually carried out a ritual mass Murder-Suicide, killing him and most of his followers, after carving a symbol into Reina to use her blood, forcing her to watch. Tokimassa's actions ultimately helped unleash the Dark upon humanity, threatening to destroy them all, an outcome that Tokimassa actively relished and desired.
• XBlaze duology: The twisted SS-class criminal only known by the moniker Ripper is a sadistic Serial Killer who, by his own admission, stirs chaos solely to alleviate his boredom. Infamous for dozens of grisly murders in the past, Ripper was eventually apprehended for his carelessness but awakened to his Drive during transport. Massacring all but one of his captors, Ripper fled the scene and attempted to take shelter from his pursuer, consequently orphaning and traumatizing Yuki Himezuru after murdering her parents. Continuing his killings for over a decade, Ripper develops a personal interest in Touya Kagari's latent Grimoire powers and attempts to break him into unleashing his potential so he can have a good fight; this includes torturing his friend Hinata and cruelly relaying the story of what he did to his guardian, Yuki. Although Ripper is slain when he pushes Touya too far, death was not the end for him. Returning in Lost: Memories under the new designation Freaks, a moniker he proudly embraces, Ripper was accidentally resurrected when the Magic Guild researched his Seithr-laden corpse and split his consciousness between himself and an amnesiac, Kiri. Subtly manipulating Kiri to regain full control of his body, Freaks is driven by nothing but his suppressed bloodlust and all-consuming desire for revenge against Touya and his friends.
• Your Turn to Die: The real Sou Hiyori—also known as Midori—is a sadistic member of ASU-NARO who manipulated each of the candidates into signing the consent forms for the Death Game. Midori grew up with a fascination for humans and would enjoy torturing them physically and/or mentally until he'd broken them. Before his alleged death at the hands of Alice, Midori and Shin Tsukimi had been friends, but Midori would enjoy doing things to freak Shin out and seeing his reaction to the point that Shin looks almost ill having to recall it. Prior to the game, Midori manipulated Keiji into killing his childhood hero by accident, scarring him for life. Midori enjoys tormenting the participants with an innocent smile on his face, especially the Dummies. This includes gaslighting Sara into believing she's a Manipulative Bitch who's willing to let the other participants die to win the game; replacing Mai's arms with his own severed arms; and turning Maple—who he had configured to love him—into a deformed killing machine.
