This guy is from the Manga series MW by Osamu Tezuka, easily his darkest work, and he's a nasty piece of work. He's been compared to Johan from Monster, and rumors exist that he was the inspiration that have never been substantiated.
== History ==
Michio Yuki was once a shy and intelligent 4th grader, who was kidnapped by a gang of hooligans during a family boating trip onto an island that was secretly used as a testing facility for a chemical warfare gas by the US government. Michio, and his kidnapee Garai, were the only two survivors, due to hiding in a cave overnight as the bombs went off. Michio, however, was exposed to just a small fragment of the gas, which lead to him developing a slow and grave illness and having his mind warped to remove all sense of conscious, only worsened by his sexual assualt from Garai the previous night.
In the current setting of the story of the 1970's, Michio is a respected investment banker in his early-to mid twenties who secretly moonlights as a serial killer and rapist of all types. He has developed a twisted relationship with Garai, who has reformed into a priest following his realization of the horror of his actions, and uses his guilt to lead him along on his heinous actions. Michio eventually reveals that his murders are for the grand purpose of getting a case of MW so that he can manufacture it all around the world and unleash it to annihilate mankind.
At the end of the story Garai decides to plummet with the MW casket into the ocean while on a plane to his death to prevent Michio from being able to manufacture the gas. His near-identical older brother was on the plane with him and was deliberately imitating his appearance, and he pretends to be him so that his brother is shot and killed instead of him, with Michio continuing to imitate him. (He's still dying though).
== How evil they stand out ==
In the first chapter alone, he kidnaps a man's son and then kills him while pretending the son is still alive to extort money, and then runs the man over with a boat, a tactic he repeats with his boss. He sleeps with and poisons his bosses daughter and performs this tactic again, going as far as imitating her voice. He later ambushes the man and gloats towards his murder before kicking him off a ledge. He attempts to out several people as gay (This is more heinous than it seems since it was the 1970's) for his schemes. He rapes a woman so hard he cripples her and emotionally manipulates her into falling in love with him so much that she tries to marry him, and tries to get another woman to marry him which he then kills. He emotionally gaslights and abuses his boyfriend Garai, and is implied to commit bestiality with his guard dog.
His crowning crime is to attempt to destroy the human race with the MW gas, which he nearly succeeds in, taking numerous children hostage and threatening to kill them, as well as manipulating his brother to be mistaken for him and killed.
== How severe is the prevention ==
As awful as he is, he has a few preventions that stop him from being Pure Evil. For one, he has agency issues as a result of turning evil in the first place due to brain damage from chemical exposure, and being a victim of rape also compounds this and creates some sympathy for him. (Similar to the disqualification of PE of Vittoria from Red Robin). However, he's demonstrated to be aware of his evil nature so this is a minor prevention. Secondly, he cries genuine tears when Garai sacrifices himself and refuses to kill him, demonstrating he cares about him on some level despite his continuous abuse.
== Verdict ==
Near Pure Evil.
