Ikasui

Ikasui ([http:// 胃][http:// 下][http:// 垂], literally meaning: "gastroptosis") is a former criminal organization that was originally organized and founded by http://naruto.wikia.com/wiki/Orochimaru after departing from http://naruto.wikia.com/wiki/Konohagakure. The group consisted of what  http://naruto.wikia.com/wiki/Orochimaru considered to be his best experimental beings. The group's original and intended purpose had been to act as a web for criticism and accusations that would go against himself and http://naruto.wikia.com/wiki/Otogakure. However, the group quickly defected and created goals of their own. Before http://naruto.wikia.com/wiki/Orochimaru  could seek to eradicate the traitors, they'd already have gone without a trace. In Parts I and II, Ikasui is led by Ashura Aka and engages in multiple battles throughout the series. After Ashura's death in Part II, Sumiharu comes to leadership and redirects the group after the http://naruto.wikia.com/wiki/Fourth_Shinobi_World_War to affiliate with Konoha.
