>>713383523>All things point to Kanako still being aliveAlive, yes, but only technically. Ceroba outright states that Kanako's fallen down, which is the state a monster takes on shortly before dying. This is part of why she gave Kanako to Alphys for her experiment, which we see in-game. Based on this, and based on the events of Undertale which shouldn't be excluded since UTY is meant as a prequel to UT, we can pretty safely conclude that Kanako is just going to end up like the rest of the monsters given to Alphys' experiment, and we all know how that turned out.
>Ceroba outright says she can feel Kanako is aliveIIRC she says that before leaving with Clover for the Steamworks, and we see in-game that basically everything she says to Starlo and Clover around then is just a massive lie to get Clover by themselves so she can steal their soul for Chujin's serum. Ceroba isn't a boss monster in the final version of UTY, so it's not like she can feel Kanako draining away her soul energy as she ages, she's just bullshitting there. As for detecting Clover's "purity", I'm not sure how much stock I put in that being something you can actually "feel". Sure, you can measure whether or not a soul is "pure" by seeing how much EXP and LV it has, but the only person we've seen who can actually do that reliably is Sans, and he's a special case. Plus, even is this ability isn't exclusive to Sans for whatever reason, I'm not convinced Ceroba is a good enough judge of character to be able to sense Clover's EXP and LV either. I mean, she seems basically clueless as to what happens to Starlo when you kill him in a neutral route, only abandoning you after realizing you're "impure" later on, so I'm pretty sure she's going off a vibe more than anything, like how Sans can vaguely tell how many times you've died to him based off Frisk's facial expression, but isn't able to tell after a while.
