What I Don't Understand About Soul Eater

1) Whose Crona's father?
2) Does Soul have parents?
3) What does Lord Death actually look like?
4) How does Soul play the piano so good?
5) Why is Soul named, "Soul"?
6) What do Souls feel like eating them?

2)-> I don't exactly know, but his grandmother is mentioned a couple of times and he has a brother.

3)

4) Soul actually comes from a family of rich musicians. When he found out that he was a death weapon he left him family to become a Death Scythe instead of a musician.

6) Hmmm, something tasteless with irresistible texture... almost sounds like eating something like are but with the texture of gum that you jus kind of want to eat. ♠

Hope these helped.

Oh my gosh how do you know this stuff!

Well I knew 3 & 6 from the anime.
The others, I had the help of wikia because it's in the manga that I don't have with me.
