Comparing an unborn baby as parasitic worms? LOL.
Parasitic worms never will grow up to be someone who's potentially smart and and such. Y'know, I'll post this again. Yes, it's a doujin page, but as far as I'm concern, it's a CANON doujin page.
Naomi lives. In death, Raye Pember saves her life by giving her the life of a child in her womb. Naomi lives on as a single mom, i.e. MILF, with the knowledge that Light Yagami is Kira, but choosing to not come forward with this knowledge for fear of dying for real and leaving her only child alone in the world.
So, Naomi Misora is the only character in Death Note with a happy ending.
