I wonder what the specific dates in Ciconia are there for.
In Vier's backstory it is mentioned that she goes missing in Oslo in December 9th and her (fake) charred body is found in an incinerator of December 11th. Of course this is just a reference to Takano's death, but it is interesting if we put together a timeline of these events.
Another thing to note, in the Siblings' Day data fragment, it is mentioned that the last sunday of every month is sibling's day. Since the story ends on December 25th, we know that this siblings' day takes place in the past since if the last day (December 31st) was saturday (if it was sunday, it would be impossible since Gunhild is already dead) then December 25th would be sunday which also conflicts with what was happening in the world and that Gunhild is dead by that point I believe. The main takeaway is that in that data fragment, Miyao is completely alone and has no siblings of his own (Gunhild mentions this) which means Meow probably does not exist yet. That just lends creedence to the idea that she is implanted.
