Manipulation of Corruption

Introduction
The manipulation of corruption is a very broad, well rounded ability seen in use by the so called "Demon God" of corruption, Rinraku no Youjin Kageki. The in depth list of what, exactly, is defined as "corruption" and can be manipulated as such is unreasonably long, so will be covered in broad strokes here.

Nature
The manipulation of corruption is just as it appears at first glance. No doubt when one thinks of "corruption" they think of, perhaps, corrupt politicians, rotting food, "sinful" minds, polluted air, etc. All these are varying examples of corruption.

Corruption, when put simply, is change in the nature of one object into something else, usually in a decaying fashion. With that in mind we shall look at some of the ways it's categorized.

"Natural" Corruption
Natural corruption is sort of redundant in its wording, as corruption itself is already somewhat "natural", but here it is used as "corruption of nature". When a fruit falls from a tree, it will lay on the ground and eventually start to rot away before becoming nothing more than nutrients for the ground. This decaying effect, in itself, is classified as "corruption" as corruption is the changing of an object from one state to a "lesser" state.

The manipulation of corruption can allow a person to make fruit rot more rapidly, or even slower. It can make dying trees live or die faster. In there lies the first problem with this power, in that it cannot manipulate what is not already corrupted in the first place.

Bodily Corruption
Bodily corruption applies to things such as disease, mutations, or most any illness that deals with degradation of a mortal body. The manipulation of this can allow someone to destroy sickness within a person's body, erase mutations, or even make it all work faster or appear worse. This same applies to poison.

Same downside as previously mentioned applies here; this power cannot affect those who are not already corrupted. All things considered, Kageki, being an embodiment of corruption, can corrupt a person, but until then they are free from his power in this area.

Mental Corruption
Often times you may hear of a corrupt government or government official, or perhaps just as simple as a mind corrupted by sin. Such things as well fall under this power's control. One could use this power to manipulate those tempted by sin or corruption into doing their bidding, or at the very least tempt them moreso, for the more stronger willed among those inflicted.

Once someone's mind has been corrupted, it can then be manipulated in many ways, including, even, ignoring the being using this power on them all together. This works well with Rinraku no Youjin Kageki in that he can whisper tempting words into a person's ear and they would never know he was there.

Spiritual Corruption
Some thought to be inflicted with corruption of the soul can be seen as evil, or perhaps fallen. When this occurs, though rare for it to be under this power's control, one could weaken someone's spiritual resolve and effectively weaken them magically or destroy their willpower.
