Myślę, że bardzo ciekawie film zinterpretował użytkownik 'Content Deleted' na YT. Polecam przeczytać wszystkim tym, którzy podsumowują całe dzieło w "wiele wątków, wydłużonych ujęć, wiele krwi i to wszystko co można o tym filmie powiedzieć".
---------------
The first killing scene at the Bus symbolizes the girl's childhood, they are pure, happy, and free of worries. But before she realized it, it is all gone with a violent wind (first reality check). A person's innocence suddenly became tainted with the first taste of real world (everyone on the bus symbolize her innocence and they all got cut into half with blood spewing all over her). The main character then started running, trying to get the childhood that she lost back. Along the way, she found some Innocent bystander (her innocence) and tried to save as many as she can, but the world is cruel and they all get blown away with the violent wind.

The scene move onto when she is on her way to school, she looked very confused, unsure why she is even here. This symbolize her school life. She doesnt know why she even wants to be there nor what is she gonna do there. As the movie showed she is completely clueless in classroom. But her courage (Aki, Sur) brought her to move on with her childhood and keep moving forward, yet, School life is what we call a preliminary reality check. You get a B it's a death sentence, you skip class, it's a death sentence, you do anything wrong, it's a death sentence (teacher killing everyone with machine guns). She doesn't even understand why it has to be this way, and they were all thrown out of school without a single hesitation (graduation), on her way out, her courage (Sur) tells herself "Life is surreal, don't get consumed by it". The girl then started running again toward the path of relentless life.

Next scene, the girl finally escaped school life and is now in her twenties, finally thought to have some freedom for herself. She started to have to do everything on her own, all the chores, adulting, all the tedious life tasks makes her feel she is a completely different person (Keiko). She is then immediately pushed into marriage by social pressure (hence all the people laughing at her while she sat in the patrol car). Before she realized it (again, just like the childhood) she gets pushed into a marriage with a person she completely disgusts. As she step forward on the red carpet, unsure if she really wants to be married, yet she also thinks there is no way back (all those fake friends in the back kept on pushing her wanting to see her suffer, wanting to see her walk the same path of suffering that they all went through). However, she mustered whatever courage she can put out again (Aki showed up again) and she fought, yet the biggest social pressure is her parents (two black suited nemesis women). However, she fought and ran, she ran forward again toward the path in life.

Next Scene, life is like a marathon. She kept on running forward. With all the experiences she gained as she becomes more mature in this marathon called life, she felt she had become another different person again (Izumi). Luckily sometimes she still gets to meet those who are positive in her life and guide and encourages her to never stop running (Her runner friends), and it reminded of her wonderful times of her life (positive memories) and it kept her running and she tells herself to never give up. But no matter how fast she runs, her parents and those who wants to possess her kept on chasing her(black suit nemesis women and pig headed groom). At this time again, her courage (Aki) showed up again and tells her to keep running and take another route (focus on her own career), and before she jumps on (literally jumps on to a diffrerent path), her courage reminded her again "Life is surreal, dont get consumed by it", and as the crowd cheers on, she runs and runs and the road on career is a lonely one.

Next scene, she runs into the cave, where countless work and pressure suffocates her as if they are trying to kill her. (The dead innocence taunts her, because of who she is now, they are all dead) She is again not sure why she is on this path where the priority is not sorted right (losing innocence and herself for the sake of career). and her courage showed up again, and she took the road to life and started running again. As they kept on running, her courage wanted make damn sure that she does not forget who she is and made her scream her name and lets her know don't ever lose her identity. Don't ever forget what it is that she really wants. The girl suddenly feels she has returned to her innocent days (As her shape returned back to Mitsuko)

Next scene, she escaped her suffocating career and met a man, she thought this is the person she loves. However ultimately she realized that her marriage is nothing but a scam to get her to bear child for somebody that she end up doesn't really know. Then suddenly she got it, as her courage in her youth reminded her "if you don't want to be controlled by your fate, you must do something completely sporadic and spontaneous so that it will catch fate off guard". She refuses to let her fate (The old man that's been controlling her the whole time using the joystick) be this way. She finally understood why so many people suicides, but that is not the way to go. Instead of take life by surprise and suicides, she must do so by readjusting her view on life, not ending it.

The scene moves to the final scene, where she lies down on the snow. This part symbolizes the ultimate message of the whole movie. Just when you thought that she had finally given up and lay down on the snow (usually laying down on the snow in this fashion means killing yourself), but she spontaneously got up and ran, and she continues to leave foot prints down in this cold relentless world as a sign of her innocence and that she once lived proudly.
