憤

Note: this word in Japanese has the idea of "indignant". So aroused here refers to being aroused because of anger over some unjust or wrong act, unfairness etc. It doesn't seem to carry a meaning associated with arousal in the sense of sex or pleasure. So, my story: think of the angry state of mind aroused at finding all your clams buried under your haystack stolen, gone!
