>>23083108kronii hasn't died yet so it hasn't happened yet. Kronii doesn't know about it. It will happen though.
alternative headcanon: there have actually been billions of kronii reincarnations. Though the earth is only 65 billion years according ot humans with our sense of time conceptualizing near the beginning of the universes creation. Each Kronii lives for a billion year and then passes away into nothingness with the accompanying boros taking kronii's form and becoming kronii. Thus why kronii retains some snake like features. Each Kronii has no memory of this process and instinctually goes to a "divine" forest to collect the next boros. This is also why kronii claims to be 60 years old becuase to her each billion years and reincarnation seems to her as another passing year.
