This is confusing me half to death!!!!!!
Okay, so alot of people have been wondering what happend to his mom. Well, there are 2 answers to that.
In the manga, it said if you want to see your mom you have to go to the other side, which means she's probably dead.
But on the wiki, it says something about Kid being apart of Lord Death and when he became powerful enough, he detached and became the next LD.
WHICH ONE IS RIGHT?!?!?!?!
