Roma is a mysterious girl that is on a mission to collect “human greed” through the use of various magical objects that have unique powers. When humans use these magical items to satisfy their own personal emotions, such as love, their greed level increases and Roma is able to steal their excess greed.

The people that use Roma’s objects seem to always let their greed destroy themselves, putting themselves in a worse situation than before. 

Kenn's Comment: This one is pretty interesting. Human vices are one of the most important things in this one. Driven by desires, humans use the items that Roma gives to them - magical items that help them achieve their immediate desires. It almost always ends badly, with badly not being that bad. Often, the 'bad end' is good end. Most of the focus characters are blinded by desire and often need a sobering slap of reality, in this case, the traveling magic peddler Roma.

If the series took a darker route, Roma would be a demon who exchanges magical items for human souls. It'd kind of be like Faust in a way.

Anywho, each chapter pretty much standalone, with Roma being the only permanent character. It's a pretty good read and the art is superb.
