Life Reading

    1. Shounen (both Kaburaki and Hokuto) sees the abnormality of the life reading in both perspectives.
    2. The life reading, in both perspectives, oscillates between 5 and 7.
    3. The reading then stabilizes at 6
    4. In Coco's path, Hokuto tells others of Sora being RSD image, number drops to 5 after the searching in same day.
    5. The position tracker shows no sign of irregularity.

    Let's see who are the people in both timelines:

    2017: You'haru, Takeshi, Ryogo, Coco, Tsugumi, (Sora), (Pipi), (Chami)
    2034: You'aki, Ryogo, Hokuto, Sara, Tsugumi, (Chami?) (it is unsure whether Tsugumi brought Chami with her in 2034)

    Also in 2017, Yoichi, You'haru's father is down in either IBF or HIMMEL.  I think if a person is in HIMMEL, he or she should be detected by LeMMIH's bio scan, since HIMMEL is technically a part of LeMU (Sora's mainframe/memory is there).  But 12 hours is needed to undergo decompression if one is to go from IBF to decompressed LeMU, Yoichi should not be in HIMMEL by that time.  Also, Sora would more likely to notice that from the position tracker that a person is down in HIMMEL (thus telling others).  Therefore, it is unlikely Yoichi has anything to do with this in 2017.

    What about Pipi and Chami?  Pipi is a robotic dog, therefore it is very unlikely to be counted as a heat source.  Chami on the other hand, may cause some trouble.  Chami is always with Tsugumi until she's injured in the warehouse, and the bio scan is most likely to register Chami and Tsugumi as one heat source--that is if Chami stays in Tsugumi's chest.  It is possible that Tsugumi lets the hamster run free for a while, but the position tracker, which proves to be usable to track down Chami later on, does not show sign of extra dots.  There is a possibility of Chami being small, LeMU forbids visitors to bring pets (I guess robotic ones are excluded from this rule), the life scan gets confused with the weak signal of Chami.  BUT, since even without Chami in picture, and assumed Sora is being counted, the counter cannot go down to five.  It is safe to say this possibility is eliminated.

    An important concept with the bio scan is... Whether the position tracker and the life reading are dependent of each other.  In a most logical sense, they should be.  Therefore it is utterly unreasonable to see difference between the outcomes from either part of the system.

    There is no evidence support that Blick Winkel itself can be detected by the heat sensor.  Blick Winkel is not a 3D entity thus it has no body heat.  It did something, however, to cause the oscillation of numbers (explained later)

    Sora is not a heat source, but, it is probable for her to be counted both on the life reading and the position tracker.  In the first four scenarios, Sora's illusive nature is not revealed until later.  She accepts the number "6" at this point, while others think she is human.  It is most likely that Sora is default count as a human in the system settings. Think about it.  Sora has plenty of opportunities to tell others about what she really is, but not only she chooses not to, she also doesn't want to.  (Such as Takeshi offered her drink several time yet Sora only politely refuse him without telling him she's an image only.) In Coco's path, You'aki explains the reason for covering for Sora: she things it is the best for Sora to tell the truth herself.  You'aki's attitude may also be the case for You'haru in 2017, where she knows Sora probably just wants to enjoy being human, and does not care about the "6".

    Another proof on Sora wants to hide her identity: in 2017, Takeshi goes to Security Room, Sora is doing something weird and failed to generate an image of herself.  Takeshi thinks she's in a corner, and attempts to go look for her.  Sora stops him right away.  She's trying hard to pretend to be human; it would only make sense that the life reading doesn't leak the news.

    What's the probability of Sora's being counted?  Sora is more reliable than You on terms of faithfully report the status of a situation.  I think You also knows about it because it is unlikely for her to not raise up and ask questions.

    In Kid's perspective, Hokuto goes back and see the life reading is 5 after the searching from the first day.  Also, it seems that in Coco's arc, when Hokuto tells everyone Sora isn't a real person, she was not counted in the life counter (info will be confirmed shortly).

    What's left is why the number is always changing between 6+-1.  Without other forms of explanation, the culprit has to be Blick Winkel... just as we contribute other things that are ordinarily unexplainable in Ever 17.  The important assumption here is, Blick Winkel's conscious affects the outcome of life reading.  There are other situations can be explained with this assumption. In the four normal scenarios, nobody knows Sora is an image until later in the story, therefore the number 6 has to be the truth to Blick Winkel (with Sora counted as a person).  Whether the player takes on Takeshi or the Kid's perspective, both Sara and Coco are in the May 1st prologue.  So the number "7" is probably when BW thinks that both Sara and Coco are stuck in LeMU at the same time. As the moment of Blick Winkel starts to doubt Coco and Sara's existence (taken accounted that they cannot exist together?), the number goes back to 5.

    At last, regarding the meaning of "Life Reading: 1" in the ending clip for first four scenarios... My interpretation is either because 1) it is Sora, she cannot leave LeMU or, 2) still the work of mind of Blick Winkel: as the company is away from  LeMU when it implodes, the only one *may* left there would be Coco (if you in Kid's perspective in 2034) or Sara (if you in Takeshi's perspective in 2017), since BW doesn't see those two girls exist side by side.  Both of them are equally valid (or invalid), yet neither is overwhelmingly convincing to drop the other possibility.  Even Sora is still being counted as a person after the implosion (yes, I think Sora would turn the setting of herself being counted as a human off after she revealed her true self), it is unlikely that she is still operating when LeMU is completely flooded.  Perhaps when the player leaves LeMU, Blick Winkel is still suspicious of "why Coco/Sara isn't here?", thus leaving the "1" on screen.    After all, maybe it is just a suspender and a way to tell the player that, "you have not solved all problems and the game is not ended yet!".
    It most likely something surreal since... well... LeMU was to implode... yet the Control Room is not even scratched and still having electricity and sensors?
