Kusuna was Yomi's second-in-command of their team in their quest to destroy Shion and to release the demon, Mōryō. Before the mission began, Kusuna was infused with Yomi's dark medical ninjutsu so that he could act as a catalyst for his team. After ploughing through the temple's defences, Kusuna and his team confronted Shion and prepared to kill her, but were stopped by Naruto. His sudden arrival and production of a large amount of shadow clones drove them back, until Kusuna ordered Gitai, Setsuna, and Shizuku to use their multi-element combination to get rid of Naruto. After Neji, Sakura, and Lee showed up to save Naruto, however, Kusuna had his team make a diversion while he went after the fleeing Shion.
