Does bakura die? - Answers

No but part of his soul has been transferred into the millennium puzzle. It is not clearly shown whether Bakura died or not. In the real past, Zorc, who had been controlling Bakura, was transferred into the Millennium Ring like the Pharaoh was transferred into the Millennium Puzzle. The real Bakura may have died long ago while Zorc and the Pharaoh stayed in their Millennium Items until the modern time and in the Memory world.
