The entire game canonically takes place over two-three months.
Huh that's interesting since my fastest Nine-Tail Kiyoko save was around 10X-11X in-game days, which is almost 4 in-game months (I had an obsession of making new run repeatedly and finish it in one go), mathematically 96+1+2 days at best.(still more than 3 months plus missing the Kinu weapon suggestion/sick/recovery scene and other holidays scenes as well)
As hilarious as flooding Komari's den with kits while freeing Kiyoko is, I guess that never really happened canonically I suppose? (Despite full dialogue variant from Kinu-Siblings and Kiyoko-Children(General) only fully accessible around that time, though I noticed that the requirement is actually less than 32 though I am not aware its exact number, I guess it is for gaming purpose/grind reward for the player)
PS: Funny that one of the last variant of Children(General) dialogue from Kiyoko, PC noted that they may had over 75 kits or more despite the requirement for it to happen are way lower, I guess in terms of kit count (not necessarily happened inside the orb) that still happened canonically my guess were.
As for ethic concerns (subjectively) that PC are supposed to save Kiyoko as fast as possible though I find it a lil conflicting given the timing of the orb siblings content only accessible after a significant time has passed. (Though in-universe PC was never supposed to figure out the most optimised route so it sort of explainable for it to be implemented canonically)
Also noted that Kiyoko use of the terms 'soul', one is from the physicality being ripped off dialogue and another is from the "Floof Flood" scene from Kinu's play with Mother options as far as I am aware of, despite the nature of kitsune itself, citing the floof god himself, "dead inside". (Just a minor nitpick though
)
While I can't fully agree with the direction Kinu is heading towards (Inari route specifically, can't bring myself to pick the options for Hime route so haven't red it, one day perhaps), I suppose that is the intention behind the writing is it not, and it is far too early for me to judge the content as it is for obvious reason (I definitely would like to know thoughts behind her characters obviously if Tob is willing to bring it up). Also props to Tob for making a wood like me to feel emotionally attached for fiction characters which I haven't been able to for a long while (given that I still enjoyed the Helia/Helspawn content for what it is back then and it was even more fleshed out in CoC2 with Kiyoko, geez these gushing are started to get out of hand...or tails I guess), good work.
