Aura Detection Explanation Post

In Change Guy, when people get an aura strong enough, they can see other people's aura's. It's never full explained because nothing in Change Guy is, but as far as my head canon goes, it follows stages like this:

Stage one:
Seeing Aura with one's eyes.
Jin-Ho has achieved & mastered this. He can see people's life energy, chi, chakra, soul wavelength etc automatically, with no effort. In fact, he couldn't even turn it off if he tried.

Stage two:
Feeling Aura with a sixth sense.
Jin-Ho has achieved and mastered this. He can feel the aura of anyone in his range, and even track people by the aura. In fac1, this requires some small effort, but normally, it is automatic and can't be turned off.

Stage three:
Reading Aura to feel what people will do.
Jin-Ho has achieved this. With some focus, he can see what people will do (in a manner akin to Nude Descending a Staircase, that is to say, he sees all the motions within the next few seconds at once. In fac1, this is pretty hard to do, normally it would be a lot easier, but it is never automatic.

Stage four:
Seeing a detailed aura.
Jin-Ho has achieved He is able to see what would essentially be a visual metaphor for a person's personality and their current mood. In fac1, this would take the same amount of effort as stage two, but would be automatic and stuck on otherwise, until Jin-Ho learns HOW to turn it off.

Stage five:
Reading damage.
Jin-Ho is far from this. This is the ability to read a person's aura and see exactly how damaged they are-even being able to tell broken bones, internal damage, etc, and how long it will take to heal. It will take about the same effort as stage three.

Stage six:
Reading power.
Jin-Ho is far from this. This is the ability to see exactly how powerful someone is, and combined with stage four, allow him to get a good grasp on the level of skill someone has as well. It would take about the same effort as stage five.

Stage seven:
Total reading.
Jin-Ho is a million years from this. This is the ability to completely know a person's full potential for strength. When used, it combines absolutely all the other stages into one supreme version of insight as well. Basically, if he achieves this, he will be able to know a person's strengths and weaknesses of body and mind at a glance.
