Kara Actuation Arc
When word that the cell of the First Hokage was stolen from Konohagakure spread, the Fifth Raikage sent a three-man squad consisting of Kakui, Marui and Omoi to reclaim it. Upon arriving, they learned that the previous holder of the target, Sakuya, had been killed and the cells allegedly stolen by Konoha-nin. Omoi's team soon found the Konoha-nin. Before a fight could break out, Omoi recognised Konohamaru Sarutobi, who explained the situation. After they deduced that the real culprits were shinobi from the Land of Haze, the groups joined forces to hunt the enemy down.

Along the way, they were intercepted by Deepa, who was also looking for the Hashirama Cell. Omoi's team decided to face the new threat while the Konoha-nin moved on. Despite their best efforts, Deepa proved unfazed by everything they attempted. With his body immune to their attacks, Kakui and Marui were soon defeated, leaving Omoi on his own. Ultimately, Omoi was soundly defeated, and Deepa began questioning him about the Hashirama Cell's location. While he refused to speak, Kakui and Marui soon recovered. Refusing to let Omoi die, they revealed that the target was on its way to the Land of Haze. Deepa promptly killed Kakui and Marui by thrusting his hand through their chests.
