Derank to Death

When someone dies on Betajam Island, their Cyn loses a bit of progress to the next rank. When a Cyn dies in human form, they still lose the same amount of progress to the next rank as if they were in Cyn form. If a Cyn is near zero progress to the next rank, death brings them below zero progress and causes a derank. However, if a Cyn does this at the bottom of Space rank, they die and lose their Cyn form. For dying in human form, this means they lose their ability to turn into Cyn form. However, if they die in Cyn form, they don't vanish from existence. Instead, they Derank to Death.

When a Cyn deranks to death, their Cyn form gets separated from them. However, before it can vanish, the Cyn form actually fuses with the human form to create a human-Cyn hybrid. Each hybrid has a slightly different appearance: Any humans sent into Forced Rebirth will be able to get a Cyn again, but according to the rules of Forced Rebirth. However, if it is opposite ends of the Cyn Clock, then a strange occurrence happens. The Cyn in this case failsafes to cat, which is the only way to legitimately get a cat Cyn.
