Sister and the black-haired girl are the same person.The entire game is a dream of Sabitsuki's as she lingers on life-support. The rooftop ending (keeping the effects) is Sabitsuki holding onto the last shreds of herself and leaving on her own terms before.It wants to wait until Sabitsuki/Rust is ready to go outside to look at the world one last time, delivering the crushing blow just before she's ready to let go for good. flow is only just waiting to unleash itself onto the real world to finish Sabitsuki/Rust off for good. flow taking over, influencing her to surrender all of her effects - everything that made her Sabitsuki - as she reaches the end of her life, thus giving up what little strength she had and causing her to lose sight of herself, simply becoming "Rust.". flow telling Sabitsuki that she is, effectively, trapped and cannot escape no matter what. The prison could represent a feeling of entrapment due to Sabitsuki's illness, perhaps meaning that her hospital stay felt more like a prison sentance could be a reminder of some past crime (possibly committed with a handgun or steel pipe.) that she may or may not have been caught for or it could be.The industrial maze and the rusted picture world are meant to be confusing and claustrophobic, as well as dangerous due to the plethora of hostile Kaibutsu, weakening Sabitsuki's resolve and instilling feelings of despair and fear. flow taunting Sabitsuki, saying that that's where she's going to go when she dies. Eventually, the red demons break out into other areas, diminishing the last of Sabitsuki's health. The microscopic world is a look at the ill but strangely serene state of her cells as they succumb to the illness. flow showing Sabitsuki the state of her own body corrupted with germs (red demons) and with a weakened immune system (the black-haired girls dying off). The famicom world is based on her memories of video games she played as a child, and still plays to pass the time to this day.There are also lonely city streets, dark alleys, dingy apartment buildings, creepy overgrown gardens (possibly hospital courtyards, given the presence of sick children in some of them), bars, sewers, nightclubs, piers and the ocean, and cold snowy factory areas - all places in or near Sabitsuki's town. The school was where Sabitsuki used to hang out with her friends until she became too ill to go anymore. Most prominent are the hospitals, bringing to the forefront Sabitsuki's illness and a traumatic childhood of seeing many other children die around her. The worlds are more reminders of her past.Should Sabitsuki attack the Kaibutsu in an attempt to deny what's happening to her, they retaliate, so as to crush her spirit even further (sealing her in a room) and tell her that her fate's been sealed (killing her). flow's way of showing what eventually happens to anyone who interacts with it. Some, like Oreko, are the few that Sabitsuki is managing to keep mostly intact. The doctor and nurse were the ones who oversaw her hospital stay, while the maids may represent other caretakers, wearing gas masks (medical masks in Sabitsuki's real memories) to keep themselves from becoming infected. Characters like Smile are memories of former classmates, horribly twisted by.A few, like the cat, ghost and broom, let Sabitsuki travel through her mind more efficiently, inadvertently letting.flow ultimately wants her to give them up. They could be considered a symbol of her remaining mental strength, as. The effects are representations of Sabitsuki's inner self, and reminders of her past (the uniform and black hood, and possibly the steel pipe, handgun, and whistle), fears for her own future (the ghost, viscera, corpse, tumbling doll, gas mask, and possibly the dress), things she enjoys (the cat, broom, headphones, and possibly the diving helmet), or simply random moments of make-believe (most other effects).Furthermore, the user will always feel compelled to return, their will to leave their homes weakened by their disease and. It is able to draw the user into a trance, and opens up their mind to explore their pasts and fears, the whole experience coming off as a really strange and disturbing dream. flow (though this may not be its real name) is actually an intangible demon or monster that is drawn to humans that have Sabitsuki's illness and interacts with them through their favorite pastimes - a computer in Sabitsuki's case. Does she doze off? Space out while browsing? Surf really disturbing websites? Or perhaps it's something much more sinister. What happens when Sabitsuki sits down at her computer.
