Split it into two sheets for Meisters and Weapons

[u]Meister[/u]

Nickname:

[u]Weapon[/u]

...Something like that. Class would be either EAT/Especially Advanced Talent (Soul Eater) or NOT/Normally Overcome Target (Soul Eater NOT), Abilities for Meisters would be stuff like Soul Menace or special traits, everything else is easily explained.

As for a plot... [s]Soul Eater 1964[/s] I got no serious ideas at the moment.
