A tranquil secondary school young lady named Mitsuko survives a whirlwind which cuts through her school transport, bisecting every other person on board. She figures out how to get away from the whirlwind, which pursues her and murders the various young ladies she comes into contact with. Disoriented, and encompassed by various dead secondary school young ladies, she wipes herself off and changes into another schoolgirl's uniform and falters onto an alternate secondary school grounds. She is welcomed by young ladies named Aki, Sur (another way to say "Strange") and Taeko. Not knowing their identity, Mitsuko admits to Aki that she can't recollect on the off chance that she at any point went to this school and trusts that she had a bad dream about young ladies being slaughtered by a whirlwind. Aki consoles her that it was only a bad dream and recommends that they all slice class and go to the forested areas to brighten her up.
In the forested areas, the young ladies muse about whether fate is genuinely foreordained and whether there are numerous substances with different forms of themselves. Sur delineates destiny with a white plume, expressing that it would mean the time it takes for the quill to fall and where it will arrive are altogether chosen as of now. Mitsuko thinks about whether there is nothing she can do to escape fate, yet Sur recommends that destiny can be deceived by essentially accomplishing something one could never regularly do, in this way changing the result. The young ladies cheerfully come back to class. Aki and Mitsuko's homeroom instructor starts class, however abruptly wields an automatic rifle and starts shooting, murdering every one of the young ladies aside from Mitsuko. Before she can fire another round, Sur and Taeko burst in, get Mitsuko, and the three stow away. Another homeroom educator, who has quite recently executed her own whole class, finds and slaughters Taeko and Sur. Mitsuko and the rest of the young ladies escape the grounds, running for their lives as they are gunned down. One of the young ladies perceives Mitsuko and argues for her to accomplish something and consider why this is going on. The rest of the young ladies are then cut separated by a whirlwind.
Mitsuko keeps on running, and afterward ends up in progressively strange circumstances where her personality and appearance change: in the first place, as a lady of the hour named Keiko on her big day, who is compelled to wed a bizarre prepare with a pig's head while her visitors (all young ladies from the past school) scoff at her, at that point later as an understudy named Izumi amidst a marathon, flanked by her companions and well wishers (once more, made up of the young ladies from the school and wedding service). In every situation, she is bolstered by a variant of her companion Aki, who either prepares her for battle or occupies her aggressors, made up of the prep and the two homeroom educators from previously. In each situation, she should escape while the encompassing young ladies are butchered in different ways.
Subsequent to experiencing a gathering of revenant young ladies who attempt to execute her in the wake of expressing that inasmuch as she lives, they all will keep on dieing, she is indeed saved by Aki. Aki advises her to center and recollect that in spite of the fact that she is both Keiko and Izumi in these situations, she is eventually Mitsuko. In the wake of coming back to her unique appearance as Mitsuko, Aki discloses to her that both of them and every one of the young ladies are in an anecdotal world being seen by "somebody" and that they will keep on hunting Mitsuko down and endeavor to execute her while butchering alternate young ladies unless Mitsuko, as the "primary character", accomplishes a remark it. Every one of the situations she experienced is an alternate world, and to achieve the last one, Aki reveals to her that Mitsuko should severely murder her. Encouraged on by Aki, Mitsuko reluctantly murders her and a gateway opens up before her.
She ends up in a lustful, soiled city called "Men's World" loaded with just men who pervertedly appreciate a publication notice for an "amazing" savage 3D survival frightfulness computer game called "Tag", portraying Mitsuko, Keiko, and Izumi as playable characters. She goes out and stirs in a sanctuary where every one of the young ladies from the different situations are exhibited like mannequins. She touches base at a room where an incapacitated old man is playing the diversion on his TV, demonstrating the different trials she experienced. Mitsuko is astonished to see full size models of herself, Keiko, Izumi, Aki, Sur, and Taeko behind a glass show case. The man reveals to her that she is later on and that 150 years prior, she was a young lady he had appreciated as a kindred understudy. When she passed on, he figured out how to take her DNA and that of every one of her companions and make clones for his 3D amusement. A more youthful form of the old man shows up close to a quaint little inn down, enticing her to come to bed with him. The old man reveals to her that the last stage is the satisfaction of his most profound wish and he advises her to capitulate to her fate. Rather, Mitsuko assaults the more youthful man, shouting at him to quit playing with young ladies like toys. She tears one of the pads, giving the room quills. Recalling what Sur said in regards to deceiving destiny, she at that point confers suicide by cutting herself, to the stun of both the old man and his more youthful self. Getting herself indeed in the start of every one of the three diversion situations, she all the while confers suicide on the transport, at the wedding church, and amid the marathon before any of the vicious situations can start. Mitsuko at that point stirs alone in a field of white snow, gets up, and flees, understanding that "it's over at this point."
