Kaname Asagiri

Kaname Asagiri is a one of the three secondary antagonists (along with his father, and formerly Sarina) of the psychological horror magical girl manga, Magical Girl Site along with its anime adaptation of the same name. He is introduced as the cruel and abusive brother of Aya Asagiri, the series' main protagonist, whom he has a pleasure torturing and beating her own sister as his “stress relief” in order to get away from his father's so-called "expectations" from his studies and is proud of it.

Unable to continue torturing Aya, he discovers the Magical Girl Site in whom his sister was doing to bestow a magic stick and now tries to use all of them to keep her and the other magical girls out of trouble.

Why He's Intentionally a Scumbag
Note: This characterization was likely done on purpose.
 * 1) To get the cat out of the room, Kaname is depicted as a sadistic torturer, and the abusive brother of the protagonist Aya who kidnaps and constantly beats up his sister for reasons by their father's so called "expectations" of his studies while pretending to act like a kind boy to his parents. After failing to have Aya to continue "helping" him relieve his stress when Yatsumura was in his home with Aya, Kaname often discovers the Magical Girl Site and seeks to manipulate some of Aya's friends like Nijimi Anazawa.
 * 2) * Despite being the villain in a Magical Girl series, he is WAY too dark to fit in this genre while not feeling like Magical Girl-like villain and feels like a Batman, or a Berserk villain.
 * 3) * Speaking of living up to his father's "high expectations", it is revealed that his father was a domestic abuser just like him who only pushes him too hard in his studies.
 * 4) ** If Kaname doesn't get a perfect high score (of 100%) or get an average score or low from his school exams, his father would beat him up if he doesn't meet expectations so that he won't be able to have his son be accepted to Tokyo University.
 * 5) ** To that point, it makes him much sympathetic despite his evil deeds, while having no right for his father to hit him.
 * 6) He is often one of the worst examples of an “abusive sibling” trope which makes him nothing more than an unsympathetic antagonist.
 * 7) He may be a villain, but he is by far one of the worst, yet insufferable characters as he gets plenty of appearances (mentioned above and below)
 * 8) Just like his father, Jiro, he is extremely sexist over hating women besides his mother.
 * 9) As mentioned in WHAS #1.1 of being like a Batman villain, he feels way to similar to the Joker, Two Face, and the Riddler combined while having similar egotisms for following reasons:
 * 10) The Joker is laughing stocker who cares more about bringing chaos to other cities and worlds, and has no qualms other to abuse his comrades (like Harley Quinn).
 * 11) Two Face has a split personality with one being normal, while another being a heartless criminal because half of his face was scarred.
 * 12) The Riddler is also more of an egotist with reliance of wanting to riddles and questions to solve his problems.
 * 13) When Aya made friends with Tsuyuno Yatsumura, Nijimi Anazawa, and Rina Shioi, he barely has any reason to possibly hate them or goad them whatsoever and would kill them in self defense.
 * 14) He also lacks no friends at all because of his father's abuse (when he was at his classroom not even talking to his classmates,  in favor of just thinking about how his “life” really “sucks”).
 * 15) * When he discovered the Magical Girl Site, he uses Nijimi's "magic stick" (which was panties that has the power to control people's minds and body movements) and tries to steal the magic sticks from Aya and her friends and nothing else, just for his cruel, sadistic amusement to have "good fun" ruining Aya's life even when he becomes much more unlikeable when he kills Nijimi without any remorse or sympathy.
 * 16) ** After stealing Nijimi’s panties, he had Keisuke to commit suicide when he tried to kill Kaname for “dating” Nijimi in front of him and just taunts him about how he’s a loser before his death.
 * 17) ** After killing Nijimi, he doesn't get punished for his murderous actions instead he is captured and tortured by Detective Kichiro Misumi, who investigated his crimes and covered it up with his parents.
 * 18) He is in fact a rip off of other anime/manga/visual novel characters like Light Yagami from Death Note, Shinji Mato from the Fate series, and Lelouch Vi Brittania from the Code Geass franchise, who also have pretty childish motivations for their delusional evil deeds and wanting to be like “gods”.
 * 19) Speaking of being mean-spirited, he is also extremely annoying when it comes to creeping and luring Aya, nonstop and won't stop thinking about his abusive father and pushing him into education.
 * 20) In the Seven Seas Entertainment translation and the fan-made translation, he completely swears way too much whenever he taunts Aya and describing his father even in the standards of the company's 16+ rating (older teen).
 * 21) His “fighting skills” are just kicking, jumping, punching, and holding the palm of his hand (whenever he uses Nijimi’s panties) whenever he commits crimes or someone foiling his plans.
 * 22) His blue hair color in the anime version looks way too similar to Shinpei Sakamoto from My First Girlfriend Is a Gal with the same hairstyle, intelligenece, and rectangle-esque glasses contrast to the manga's hair color being just black and gray (or white) on top of the black hair color.
 * 23) His dialogue is incredibly painful and repetitively uses “Scum”, “Idiot”, or “big brother”.
 * 24) He with Sarina and her friends are the sole reason why Aya was one of the most misfortunate girls and was to become a magical girl in this world, which doesn't make them as memorable villains or being her “archnemeses”.
 * 25) Despite being unlikable, Kaname gets much screen time in both the manga and the anime and what’s baffling is that he gets no character development at all, but cares about his evil plans.
 * 26) His goal of wanting just to use Aya as his stress slave, and steal the magic sticks, makes absolutely no sense. How on earth can he do that on torturing Aya and it’s very uncertain if she died or killed by him, while also unclear how he will use all the magic sticks for is not explained at all (but as to just torture or kill his father for all the abuse he did to him is the closest to his real plan).
 * 27) * When Nijimi slit his throat with a shattered bottle, he starts crawling, and monologues about how he is "not going to lose" against Aya and the girls, but thinks God is his "savior.
 * 28) ** Aya tries telling Kaname to open his eyes so nobody will be sad even if he keeps doing this and she questions what is the point of doing all of this and making everyone sad. Kaname doesn't care about her for disobeying him and seems like Aya doesn't have enough from him, once he proceeds to continue having Aya as a stress reliever, just why?!
 * 29) He even never learns about his ungrateful actions whatsoever and never gets arrested or punished for his misdeeds, even when Kichiro Misumi captured him.
 * 30) Just like other people who were abused by other abusers, Kaname barely tries to arrest his father (that way how would arresting him would affect him wanting to abuse his sister), instead he just wants him dead because of the abuse.
 * 31) He is often utterly heartless, cruel, and the embodiment of pure evil which makes him much eviler than the main villains, the King, and the Site Administrators, who are supposed to be twisted and evil with no redeeming qualities.
 * 32) He is fact over-the-time like using disturbingly creepy faces and acts like a wild circus-sociopathic child that will also get on your nerve whenever his father beats him up out of failure which was the cause for his breakdown.
 * 33) Hypocrisy: Since being beaten by his father left Kaname to be consumed by hatred from him, but considers all humans as "scums" and full of "brainless meatbags". He even described them as epitomes of the worse-ness that only validates their own lives through others like his abusive father, who Kaname thinks about him as a "real" scum to him. Thus making him less of an unsympathetic antagonist and a one-dimensional Alpha Bastard.
 * 34) Of course, he spends entirely monologuing about God, torturing Aya and others, getting away from his father is repetitive and will get you on your last nerve.
 * 35) Speaking of his father and verbal abuse towards the way he hits him because of said studying, Kaname described him as a real scum to him because he would be disgraceful in his life for not getting into Tokyo University. He believed that his father “forces his ideals” to him so that he won't tread the same path that his father did. He also described his father as "the king of losers", who has no interest in Aya, her daughter, as a "worthless kid" and a "brat living in a carefree life”.
 * 36) He is honestly no better in the second half of the manga after he was able to escape from Kichiro Misumi's house and was taken to the hospital.
 * 37) He told the investigators about what happened to Misumi but covered all the incidents that happen to him (in reality, he slit Misumi's throat and nearly killed him along with his burning house), making him a pathetic liar.
 * 38) He later helps one of the site admins, Nana, who tells her all about the Magical Girl Site and Tempest.
 * 39) * In response, after his abusive father died using Nijimi's panties, he thought he could finally start living his own life and consider that everything "sucks".
 * 40) * As Aya tried to leave, Kaname taunts her again about not being his real family and Tsuyuno Yatsumura's demise nor her friends, but tells her much of how Nana is using him for something that would destroy the King.
 * 41) He barely even mentions Aya when his father punched him for not coming home in a month.
 * 42) He doesn't care if he's a liar, evil, or has any remorse since Aya wanted him to realize all the cruel things he's done and wanted him to be happy. As much as he's like it or not, Kaname feels very "sorry" for killing Nijimi and can't have Aya just have that one slide.
 * 43) He is still unlikable when he joins Aya and her group to stop the site admins that's because he is only unheroic. Since so, Kaname is still useless and is unable to use a magic stick since Aya took his lifespan from him to stop him from using magic sticks.
 * 44) After his father died of the lifespan while he was using Nijimi's panties, he beat his father for all the pain he caused him and tries to take the panties for himself until Aya teleported it away (so he won't do anything bad). In the hospital after his father truly died, Kaname feels like he is over his father's death and taunts Aya that Kaname's father wasn't her actual father. After all this time, Kaname thinks Aya really had no idea that she and Kaname weren't related to each other, no matter how neither he nor his father ever treated you like a family, and though it's "hilarious".
 * 45) When his father died from using the magic stick (which meant that men don’t fade away and become site admins or not), Kaname “guessed” his mother whom “did very sincerely” as a good parent to Aya and now thinks since his father is finally dead he can now just acts like a laidback without him and it’s never been specific of what he is going to do about himself without his father.
 * 46) When his lifespan was taken by Aya and revealed that she was trying to protect him, he later hollers in confusion by telling her about "pitying" him and thinks that has no right for Aya to protect him or the family tearing apart.

Redeeming Qualities

 * 1) Being abused by his father for not having high efforts for his studies was well-reasonable but you should or shouldn't feel sorry for his actions.
 * 2) Being kidnapped, sodomized, and tortured by Detective Kichiro Misumi was well-deserving as a comeuppance for all the abuse he did to Aya, despite being pointless.
 * 3) He is supposed to be hated for that, no question.
 * 4) Since being sadistic and cruel, he is better off a coward and a poor fighter compared to Keisuke Naoto for all the troubles he had caused.
 * 5) He used to be good "friends" with Keisuke and a "nicer" person to Nijimi, before he double-crossed and killed them.
 * 6) He also used to be nicer to Aya and their parents, despite hiding his true nature.
 * 7) His voice actor, Nobuhiko Okamoto who voiced Bakugo Katsuki from My Hero Acadamia does a good job voicing the character.
 * 8) His character design is handsome and well-made despite being a jerk that he is.
 * 9) Kaname beating up his father's corpse is sometimes satisfying for all the abuse he did to him despite his evil plans being confusing.
 * 10) In the manga, he is actually good at basketball, and being nicer to his school’s female students and his teacher.
 * 11) When Aya took his lifespan from him in a way to keep him away from using magic sticks as mentioned in WHAS #18.7, Kaname realizes by his sister that she was protecting him from his abusive father and his aggressive tutoring of gifted students. Aya knows this when he lamented inside his room about failing an exam and his father yelling at him, and thus led Kaname to use Aya as a stress relief to solve his problem. If Aya disappears, he will tear the family apart, if he endures this.
 * 12) As a result, he does help Aya and the magical girls defeat the King and her remaining Site Admins and then used Nijimi's panties by casting Aya back to the past so that she would not be misfortunate again and prevent people from despair.
 * 13) He became better in the final chapter since he became a more thoughtful and genuinely kind boy as he got over his father's high expectations and verbal abuse with beatings. But now, Kaname even went to the beach with his former sodomize-er, Kichiro, Aya, and her friends as well, which means that his relationship with his adopted sister started to improve.

Trivia

 * He is presumed to be the evilest of Magical Girl Site unlike the King and the Site Administrators and also along with Erika Kajima/Kashima (because of the similarities unlike Sarina), probably.
 * In the manga, his hair color was originally black while gray/white on the top of the black hair color.
 * He is one of the only antagonists (including his father, Erika Kajima, Shota Arai, Nijimi’s family’s loan sharks, Kiyoharu’s bullies, Mellisa Maina Matsumoto, May and Ray Atsue, Gordon, Asahi’s father, Soji Udano, Rina’s bullies from her school (not Aya’s), Kayo’s sister’s 3 killers, Mikari’s parents’ killer, Reiko Meguchi, and Kuraki) to not cry or shed a tear.
 * Kaname can be compared with Light Yagami, the main protagonist villain of the Shōnen Jump manga/anime series Death Note.
 * 1) Both have god-complex to themselves and manipulate people that trust them and try getting away scot-free.
 * 2) Both are supposed to be very unlikeable egotists that wanted to be worshipped as gods.
 * 3) There's a difference that Light is a savior who wants to rid the world of crime and injustice by protecting innocent people from enduring punishment, while Kaname is a delusional hypocrite who wants to spread his hatred on the human race and hopes they suffer his own stress in order to get away from his father's grueling educating studies for "gifted" students.
 * 4) There's a reason that Kaname is different from Light, only because he became a sadistic torturer because his father was abusive just like him, pressuring him to study hard in a way to have his scores very perfect when he accepts going to college while Light is a egotist who wants people like criminals, terrorists, and etc. to be punished or die from their cause.
 * 5) Both go too far as murderers by killing people who think their actions are wrong or remorselessly evil.
 * 6) Even so, Light often cares about the sense of peace and justice by using the Death Note to write people's names and they die as well, often to the point of being willing to kill his family members if they are liable, making him a much more of a crazy serial killer just like Kaname's.
 * 7) * Speaking of Kaname, he cares more about watching Aya and others in pain and is willing to only kill his father, who is much of a domestic abuser just like him and pushed him into studying so hard for that.
 * 8) Both their sadism and murderous nature make them even more unsympathetic, like when Light used the Death Note to kill Naomi Misora into committing suicide similar to Kaname using Nijimi's panties to threaten Keisuke Naoto to commit suicide from using his kitchen knife to kill him for smittening Nijimi.
 * 9) Both characterizations are portrayed as delusional, sadistic, and murderous god-wannabes, as the series progresses. They often even really cared or even sympathized about their fathers' deaths (even Kaname did not even care about his own father, who often abuses him and made his life a living hell).
 * 10) Both do a good job concealing their true nature and don't get punished for their actions, whatsoever.
 * 11) There's even a difference that Kaname has a dysfunctional family where his father never cared about them, while Light does not somehow.
 * 12) Unlike Light who is far less evil and sees evil people at death's door, Kaname himself is extremely a sociopath being a victim of his father's beatings and considering Aya and other girls as harmless weaklings.
 * Kaname can also be compared with Jae Galhwa from web manhwa The Devil's Boy.
 * 1) Both are sadistic torturers that are cruel and ruthless and enjoy beating up people that are weaker.
 * 2) Both have abusive fathers who are just greedy educators pressuring them so hard.
 * 3) They are often unsympathetic and nobodies.
 * 4) They are both sexist towards women besides their loving, caring mothers.
 * 5) They get away from their actions scot-free.
 * 6) There's a difference that Jae Galhwa is a delinquent/bully whose disciplining father pushes him into studying lessons and keeps his mother and friends away because of it, while Kaname is a torturer and a humanitarian who gets pushed too hard from studying by his father.
 * 7) There's even a difference that Jae Galhwa often has friends and treats them poorly, while Kaname lacks any friends.
