Kohaku is Sango's younger brother. Kohaku and the rest of his village were called to a castle to eliminate a Spider Demon. Naraku took over Kohaku's mind and killed his father. He is now Naraku's reluctant slave. Kohaku was such a sweet boy and many choose to cosplay Kohaku. They use to get cosplay Kohaku costume and cosplay Kohaku wig to have an astonishing look just like Inuyasha cosplay characters.
