WARNING: SOME IMAGES IN SACHIKO'S GALLERY HAS BLOOD/GORE. IF YOU HATE THAT KIND OF STUFF, THEN VIEW THE GALLERY WITH CAUTION.
Sachiko Shinozaki is the antagonist of many of the Corpse Party installments. The gang's version of Sachiko is the one that appears in Corpse Party: Blood Covered...Repeated Fear and Corpse Party: Book of Shadows (game). The story of how she is in the gang is a mystery, since at the end of Corpse Party: Blood Covered...Repeated Fear, she was appeased and moved on to the afterlife. It is possible Marci, another member of Prank's gang, had a hand in bringing her into the SAMB.
Sachiko is a young girl with long black hair and bangs that cover her face. Her eyes are black, but when she's angry it appears that her eyes go blank (at least that's what they look like when her avatar is angry). Her skin looks grey, but there has been few times where her skin turned a glowing blue like the other spirits of Heavenly Host. She wears a tattered red dress, but remains barefoot.
Just like in Corpse Party, Sachiko is very sinister and torturing. But this is due to becoming a vengeful spirit after the cruel death of her and her mother, Yoshie Shinozaki, at the hands of her principal, Takamine Yanagihori.
Sometimes, she likes to play with her victims by helping them and acting as their friend, only the kill them afterward. Two great examples of this is in Corpse Party: Book of Shadows. In chapter one, Sachiko gives advice to Naomi Nakashima to save her friend Seiko Shinohara, but at the end appears before Naomi to explain to her that no matter what, Seiko was destined to die. She then goes on to taunt Naomi and wonder what other kinds of horrible deaths Seiko could have. In chapter six, Sachiko appears before Yuka Mochida and acts like a "little sister" towards her. At the end of the chapter, though, Sachiko asks for Yuka's life, and then takes a picture of her corpse to show to Satoshi Mochida, Yuka's older brother.
Due to her close bond with her mother, Sachiko at first trapped children in Heavenly Host in order to please her. At some point, in ended up becoming merely a source of amusement to her. Physically and mentally torturing others is fun and joyful for her. Because of her mother's death, she can become saddened, and sometimes angered, at the mentioning of mothers.
Powers and Abilities Edit
Like all ghosts, Sachiko can become transparent to go through objects. She can also use possession or haunt others. As seen in Corpse Party: Book of Shadows, Sachiko can also be good at deception and acting, as multiple times she pretended to be innocent to gain the trust of others. Sachiko also appears to have knowledge in torture skills.
Some "non-canon" powers Sachiko has are similar to what Marci has. Why she has them on the SAMB when they aren't present in Corpse Party is a mystery, but just like her being in the gang, it could be the result of interference by Marci. On the SAMB, she has the ability to make portals.
The only notable thing that is seen as her weakness is the mentioning of mothers. This is due to her strong bond with her own mother. In Corpse Party: Book of Shadows, when Yuka mentions her own mother, Sachiko can be seen visually saddened. However, another weakness could be using up her spiritual energy. In Corpse Party: Blood Drive, she cast a powerful spell that used up her energy, causing her to "die".
Just like with her non-canon abilities, she shares some of her non-canon weaknesses with Marci. A notable one is being sprayed with holy water, which appears to burn her upon contact. Whether this weakness could actually be canon is unknown, as other spirits in Corpse Party were harmed by holy water, yet it was never tried on Sachiko. Another is being attacked with Maria's "Demon Slayer" weapons, as they are designed to harm and kill the dead.
Sachiko is really good friends with Marci, an OC of Prank's that is in the gang. They have much in common, being young vengeful spirits who love to torture and murder others. In the Imagination Saga RPs, it's said that Marci and Sachiko knew each other for a long time and were in a rivalry. During the course of the RPs, this changes into a friendship. In other RPs and stories, it also hints that they've known each other for a long time. However, in actual Corpse Party canon, this is not really the case, as Marci is just an OC and Sachiko rarely ever leaves Heavenly Host. But in "Prank's Gang Canon", they have known each other and other characters for a long time. It often to see Marci and Sachiko team up to do evil plots on the SAMB. This is usually just to annoy others, but in some cases it was to cause evil. Together, along with Ellen, they are known as the "Trio of Trouble".
Just like with Marci, in Prank's Gang Canon, Sachiko has known Ellen for a long time and the two get along well. Together, along with Marci, they are known as the "Trio of Trouble".
Yoshikazu Yanagihori Edit
Yoshikazu's father was the murderer of Sachiko and her mother, Yoshie Shinozaki. Due to the murder, Yoshie cursed his bloodline and Yoshikazu's mental stability and free will was chipped away. He now takes orders from Sachiko, and even after death still serves her.
Yuki Kanno, Ryou Yoshizawa, and Tokiko Tsuji Edit
Yuki, Ryou, and Tokiko are three notable victims of Sachiko. They serve under Sachiko as vengeful spirits. On the SAMB, they look to her as their leader out of fear. Sachiko seems to look down on them as just minions, but there was once a time where it hinted that was just an act.
Other Members of Prank's Gang Edit
Sachiko knows many of the "horror" genre characters. It's explained in some posts that the characters would sometimes hang out outside of their fandoms. She appears to be on good terms with Moge-ko and Mary. Other characters she merely interacts with well.
Sachiko, like lots of the "trouble-makers" of the gang, likes to mess around with other members. She usually targets Arbiter, Maria, Marial, and other "leaders" of the gang.
Other than that, Sachiko doesn't interact often with specific gang members.
Other Gangs Edit
Like with Prank's Gang, Sachiko sometimes enjoys annoying other gangs.
Outside of her gang, she appears to be on good terms with "the Dakkus", horror genre villains, and any who appear as mischievous and/or sadistic.
In AR and Louie's gang are the main characters of Corpse Party. Though they interact very little, it is safe to assume that Sachiko enjoys to torment them and remind them of the events of their franchise.
(The parts that apply to Sachiko being in the gang are in italics and are not canon)
In life, Sachiko was the daughter of Yoshie and Seiji Shinozaki. While she was being born, her older twin sister Sachi Shinozaki died in the womb, causing Sachiko to absorb her. Years later, Sachiko's father died due to the curse on the Shinozaki bloodline, in which the Shinozaki Family is unable to produce male heirs and thus adopts male heirs into the family through marriage. But it comes with the price of each and every male dying a few years after their child (in this case Sachiko) is born.
Later on her 7th birthday, while Sachiko is in elementary school, she witnesses her mother fall down some stairs at school and dies. Down the stairs comes her principal, who is realized to have been chasing Yoshie. In order to keep the truth from getting out, he kills Sachiko and says Yoshie Shinozaki's death had been an accident.
After she died, she got revenge on the teacher after framing his son for murder of Yuki Kanno, Ryou Yoshizawa, Tokiko Tsuji, and herself. The school ended up getting closed down, Yoshikazu (the principal's son) was driven mad and committed suicide, and the spirits of the dead children were brought into the Heavenly Host Elementary School Closed Spaces. The Heavenly Host Elementary in the afterlife, or Nirvana, was born out of a spell Yoshie Shinozaki cast to prevent Seiji from dying, but thus failed. After Sachiko died, she took control of the school and started trapping and killing students in it. Later, the main characters of the series are trapped in the school, and the survivors succeed in appeasing Sachiko and the other ghost children and returning home. In the events of Corpse Party: Blood Drive, Sachiko returns once again to aid the survivors after they return to "Nirvana" to fully break the curse. However, this causes her to use up all of her power, and she loses her physical form and "dies".
Arrival on SAMB Edit
Due to Marci's fourth-wall breaking abilities, Sachiko meets her and characters, sometime before the actual events of Corpse Party: Blood Covered...Repeated Fear. After Sachiko is appeased by the surviving Kisaragi Academy students, Marci appears before her after the students escape. Marci tells the other ghost about the SAMB and Prank's Gang, suggesting Sachiko joins her. Sachiko agrees, which causes an alternate universe to be created in which Sachiko goes with Marci instead of moving on. In the SAMB, Sachiko returns to her normal ways of being a sadist little girl. Later on, she goes back and convinces Yuki, Ryou, Tokiko, and Yoshikazu to join her in the gang.
"Be careful. You're about to fall into the valley of past and future memories."
"Isn't it horrible? Don't you just hate us? Wouldn't you just loooooove to kill us?"
"This school is just getting livelier all the time!"
"You're so cute. I just want to mess you right up..."
"Once someone's fate passes through these walls, it locks in place forever."
"Daddy's not breathing..."
