I like this theory because it would mean that Dr. D. Light isn't dead

My statement is actually not fictitious, it seems you haven't looked it up. It isn't that common to see those people because their parents usually choose their genders but it is a real thing

I think the ending is good like this because then people can make their own theories. They wanna theorize Dr. D. Light is still alive? They can. They wanna theorize the monster isn't real? They can. They wanna picture the monster to be a demon? They can. It's perfect for fan interaction.

I really want a spinoff about Dr. D. Light, he's too great to not have one-

You DO realize that there are people who are born with no or both genders, right? It's rare but it is real so they/them is real. Look it up, these people exist.
