DD 20 themes

A few days ago, amefuri suggested doing a 20 themes list for Devil & Devil (an explanation of 20 themes can be found here). I've been rereading the manga this week and jotting down theme ideas as I go. Under the link are some I've come up with so far:


1) friendship
2) teamwork
3) saving/depending on your enemy
4) good vs. evil
5) becoming stronger/better
6) true names
7) revenge
8) exorcism
9) sharing bodies/personalities
10) defying expectations


Anyone else up for this? Post any additional themes you can think of, and let's see how many we come up with!
