Death the Kid

Death the Kid is a Grim Reaper and the son of the God of Death, so he possesses a unique power from the Soul Eater series known as 'Soul Perception'. This power allows him to see the souls of others.

Here is the Wiki page for the power.

The importance of this is that it allows Kid to see certain information about an individual. Mostly, it gives Kid the impression of certain dominant personality qualities, a general and vague idea of the individual's strength, and often an idea of the individual's species. This is not perfect, however, as it hardly gives anywhere near an absolute description of the individual's personality and can be interfered with by powers and magic--Witches in canon are able to use a spell to make their soul appear to be that of a human's.

Here are a few examples of souls:

Franken Stein, Justin Law, Maka Albarn.

Basically, this is a permission post asking what Kid would see if he looked for your character's soul.

1. Do they HAVE a soul? 2. A VERY BRIEF description of their core personality/most notable qualities, about a sentence. 3. Anything WEIRD, such as but not limited to: being non-human, being CORRUPT/EVIL, being reincarnated, etc. Whatever you think might have something to do with their soul. 4. Size: (most people's souls are about the size of a soccer ball, while very strong individuals have souls that encapsulate their entire body, and Gods have souls the size of cities or more) 5. Appearance: (This is basically for fun and flavor--souls tend to show notable physical features (Kid's three hair stripes, Stein's screw) or hidden qualities (Maka has the soul of an angel, hence her 'wings').)
