this is somewhat a major spoiler, but this thread is here for that :
this is correct.
like i said, takano's main purpose is to glorify her grandfather and herself.
she just doesn't give any damn thing about the hinamizawa syndrome, the people or her faction. at all.
several facts prove it :
1) she is really excited about any sign of congratulation from her superiors (i.e her "second" grandpa, Koizumi :
Routine Audit (Piece #19) )
2) she prepared the dreadful disaster plan.
3) if you pay attention to the role of the group, irie, tomitake and takano have the duty to determine what is really the hinamizawa syndrome and how to cure it.
so here is the question : how can they let the "queen" die like that? how can a random culprit kill rika, while the governement trained soldiers are supposed to protect her? in fact, aren't they the real culprit as mentionned several times? you know what i meant :p
4) dispite takano's comedy, tomitake discovered her real intentions, that's why he gets killed.
her whole mental state is kinda screwed, but she has a strong will (if you read the minagoroshi prologue, you will understand what i said with the "rules X, Y, Z" ).
in fact, i suspect that takano brought the whole "queen theory" to irie and the others to justify any "big mess if furude rika is killed". i'm pretty sure the queen theory is messed up just because of watanagashi-hen.
i'm just wondering one thing : the TIPS aren't mentionning anything about a huge mess / killing frenzy around hinamizawa in watanagashi-hen / meakashi-hen dispite rika's death. and as i could read with irie theory,
"all the infected populace will yield into the terminal stages within 48 hours of the main carrier's death."
this proves that the "queen theory" is kinda a big excuse, since there wasn't any mass L5 state after watanagashi and meakashi hen
(this event couldn't be ignored as a TIPS if it has really happened, like the disaster was described to have happened after tsumihoroboshi-hen))
my guess : wouldn't be possible that takano couldn't activate her emergency plan in Watanagashi/meakashi because she couldn't find rika under the 48 hours? (if they aren't able to put the village under a possible mental disorder under the 48 hours, there is no "valid excuse" for takano, so no disaster :p)
if she can't find rika (or her corpse) within the 48 hours, this will make the queen theory null and void.
