Koukon (黄昏, Dusk) is a spy organization, disguised as a mercenary group of ninja from Genin to Jonin in rank that work for relatively low income. Only two ninja amongst them is a missing-nin. The others never belonged to one of the Great Nations. It seems their ambitions include protecting Konoha, and finding Tora Mazuka among other things. At the current moment they have a total of six ninja; five Chunin, and and a Genin (though he has Kage level strength and ironically is the leader). Their leader, who is Sasuke is said to have massive amounts of chakra and Kage-level ninjutsu.
