Chino asks Sasuke if he plans toreturn to Konoha, which Sasuke doesn't reply because he isunsure about it due to the guilt he feels for betraying hisfriends. She also asks him about his goal of restoring theUchiha Clan, which he again refuses to answer. They comeacross the village where Iou's daughter lived in and find itcompletely destroyed. Sasuke asks why the neighbouring villagesaren't helping to support the residents, and Nowaki repliesthat the other villages are afraid of the Dark Thunder Group.As Iou describes the group's activities, Sasuke notes howsimilar they are to his old self; someone who turned to hatredand darkness after losing someone he loved dearly. Sasukeadmits he still feels some darkness in him, but the purpose ofhim travelling alone is to repair the damage he caused tohimself and prevent another mistake. Chino senses movementunderground and suspect it is due to the Dark Thunder Group.They rush back to the village and find that the group isalready setting off explosions in the village.

When heheard about Sasuke attacking the Kage Summit, Karyū startedto admire him and formed the Dark Thunder Group to get revengeon those who wronged him, much to Sasuke's dismay, and Sasukesends a message of the events to Kakashi.Kakashi quicklyresponds to Sasuke's message and informs Sasuke of the attackon Konoha. Sasuke remains in the village to continueinterrogating Karyū and then turn him over to Konoha. Sasukethinks about Karyū's story about gathering other rogue ninjasto get revenge on those they despise and forcing a genjutsu onother shinobi to fulfil his goals. He spots a fire breaking outin the house where Karyū is being kept and learns from Chinoand Nowaki that Iou set the house on fire to kill Karyū.
