In The Lucifer and Biscuit Hammer there is a character, Inachika Akitani, who dies without appearing outside of flashbacks. He is stated to have lived for five hundred years and had amazing levels of psychic ability, especially precognition, based on a connection to the Akashic Records. He loses those abilities about the time the series begins, with no explaination until the characters and reader find out the the Big Bad's motive for destroying the world is to move back in time - meaning he has already destroyed the future world. -skyfell
...which seems to be the full story until Animus mentions seeing his next life in the far past while dying, and that it would take about 500 years of life to redeem his karma...
