Magical Girl Site Sept

Magical Girl Site Sept is a Japanese psychological horror magical girl manga series written by Kentarō Satō and illustrated by Toshinori Sogabe. It is a spin-off/prequel of Magical Girl Site. It was serialized on Akita Shoten's Champion Tap! website from December 2017 to October 2018.

Synopsis
Tsurara Takahashi is a middle school student who plays with the Shinzen tennis club by her friend Hyoka Nagatsuki‎. However, she carries a great misfortune that she can not confess to her friends: she discovers the mysterious Magical Girl Site and was given a magic stick in the shape of an electric drill, which led her to have deadly consequences.

Bad Qualities

 * 1) Speaking of the tennis coach, Kuraki, he is also a full-blown pedophile notable for having sex with Tsurara (who is 13-14), in order to blackmailed and embarrassed her along with making her life a living hell after Tsurara killed him with a driller magic stick by site admin Juroku.
 * 2) * Also, he's even a more dreadful rehash of Kaname Asagiri, whom him and Kuraki hide their personalities a secret but never get punished for their actions to put the cat out of the room.
 * 3) It tries so hard to be too disturbing for a dark magical girl series compared to Magical Girl Site.
 * 4) The subplot about Tsurara's whereabouts with Kuraki is just pointless and nothing to do with the main plot of the story.
 * 5) Hyoka just lets Kuraki's corpse destroyed so that no one would witness that, and uses Tsurara's driller stick to do something that she was not meant to be.
 * 6) Reiko Maguchi is a very sadistic teacher and lover of Kuraki, who humiliates Tsurara by putting embarrassing photographs so her classmates will laugh at her even with Akai to turn on him for making out with Kuraki.
 * 7) Akai, her boyfriend turns on Tsurara when he realized the embarassing photos of her and Kuraki making out.
 * 8) Tsurara's classmates act very out of character, hysterically by laughing at Tsurara for said embarrassing photos, and forced her to commit suicide for that.
 * 9) Some of the side characters barely get any character development and have nothing to do with the story at all.
 * 10) It tries very hard to be a serious story in horror series standards.
 * 11) Some of the site admins like Juroku do not show up in person.
 * 12) The fight with Reiko Maguchi was anti-climatic and rushed.
 * 13) Before losing lifespan, Hyoka must decide whether that she will destroy the Magical Girl Site's system, but is completely forgotten after she loses lifespan and brainwashed as a site admin revealed to be none other than Nana.
 * 14) To rub salt to the wound, when Aya went back in time to save people from misfortunate in the end of Magical Girl Site, we do not get to see whether the misfortunes of Tsurara and Hyoka were undone. But, it's likely while Nana (who is Hyoka Nogatsuki) is now the earth's new god, so Aya didn't prevent their misfortune.

Good Qualities

 * 1) Hyoka and Tsurara are likeable.
 * 2) The artwork is good and different from Kentaro Sato's.
 * 3) Unlike Aya, Tsurara doesn't have another problem for her misfortune.
 * 4) It doesn't focused too much on the bullying and abuse.
 * 5) Tsurara's pregnancy was never shown after she commited suicide.
 * 6) Reiko does get her comeuppance where Hyoka easily disintegrated her, so that she will no longer cause trouble to the school or Tsurara.
 * 7) It's very sad to see how Hyoka lost Tsurara from falling to the ground to the school building.
 * 8) It was revealed that as mentioned in later chapters of Magical Girl Site when Sept was ongoing, where it was how Nana was Hyoka Nogatsuki (mentioned in WIS #6).
