All I know is it's a Anime.
This anime/manga is partly about a girl name Maka and she tries to make her scythe, Soul into a death scythe which is like the most powerful weapon. Inorder to turn into a death scythe, Soul and Maka have to capture 99kieshian egg souls and 1 witch soul. In the first ep. they already have 99 kieshian souls but then they didn't eat a witch's soul instead, they ate a cat's soul. But the real story line is for them to defeat the witch's Arachne, Medusa, and the kieshian, Asura. It is a great and funny anime/manga.
Hmm aren't there soul eaters in Bleach? Or is it a different one? If it's something else I have no clue sorry ^-^
