ThatOneGuy said: Kimonges were the original Reisen Yukkuri before the cute Udonges came around.
Kimonges originally were associated with corruption and things of greed in general (like a fat cat) usually seen sinisterly smiling and smoking a cigarette or a cigar whilst laughing derisively post #2604 hence early Udonges saying Gera Gera as well. So not really yandere since they only have their eyes for the greens (or whatever the hell color japanese money is).
