Both ver. no diff actually in terms of story. The only thing is it just got some extra commentary by the Shinikami ...

The series is being made into an anime and air on April 7th 2008. It is broadcast Mondays at 6 pm on TV Tokyo. The series is animated by Bones.[1] The opening theme song is sung by T.M.Revolution, and is called 'Resonance'. The official Japanese website of the Soul Eater anime series has announced that each episode will air in two different versions: the regular Monday 6:00 p.m. version and a late-night "Soul Eater Late Show" version with added special footage. The dual broadcast of this supernatural action series is being billed as the "world's first evening and late-night resonance broadcast." The "resonance" term refers to a story concept in which the characters, such as the heroine Maka and her living weapon partner Soul Eater, achieve maximum power by synchronizing their souls.[2]
