The second weakest member of Kagekenin, he is only stronger than Kaci Wells. He was Kaci’s teacher. He is also the inventor of Haunted, the dark arts eye technique. His Haunted is strong enough to kill someone through its special Genjutsu. He and Kaci are the same speed. He is very loyal to Viper Uchiha, the leader.
Korin rarely uses honorifics when speaking, and even then, usually as a form of sarcasm. He is the only member of Kagekenin who does not respect their leader, Gensho, and openly declares his willingness to kill him around others. The only respect he ever seems to give is to Kaci, and even then, he is quite willing to insult him. He openly holds his partner in contempt for his love of money. Despite this, whenever Korin is in the mood to kill, the two work together flawlessly in battle.
Korin has absolutely no moral restraints regarding who he kills. He considers slaughter a calling, and often takes considerable pleasure in making his opponents' deaths as painful as possible.
Korin is shown to be a sadist taking sincere pleasure in the pain he causes his victims. His behavior borders on insanity; he is frequently heard shrieking loudly while attacking and laughs maniacally when he is about to kill. Korin also appears to be quite spiteful towards his enemies (and nearly everyone else).
However, his powers have made him very arrogant (though not quite stupid), and he frequently engages opponents with no regard for strategy. Although ridiculed for his foolishness by Kaci and Gensho alike, and being obviously inferior in tactical genius to either of them. He doesn't particularly like it when Kaci assists in his battles, and only calls for his help when he decides he needs it. Kaci tends to return the favor by coming in "late" and letting Korin lose as punishment for his arrogance.
