Ch. 421Konoha’s Fault
Kakashi revealed that his left Sharingan had awakened the Mangekyō technique Kamui, and the group connected it to the masked Akatsuki member’s matching right eye. Kakashi rejected the suggestion that the attacker was Obito, but the chapter left his unanswered doubts—and Hyuga Kagami’s certainty about Obito—unspoken.
- Kakashi told Guy and the others that his left eye was a Mangekyō Sharingan with the technique Kamui, which had transported him and his attacker to an unfamiliar space.
- Kakashi asked whether other Uchiha had shared the same Mangekyō technique, but Shisui and Itachi said they knew of no such cases.
- Shisui confirmed that no one outside the hospital room knew Kakashi had a Mangekyō Sharingan and wondered how Akatsuki had learned about it.
- Itachi noted that Obito had given Kakashi his left eye and suggested the masked attacker’s matching right eye was likely Obito’s; Shisui inferred that the attacker wanted to reunite the pair.
- Kakashi insisted Obito was dead and claimed the attacker had merely obtained Obito’s eye, but Guy’s question about why the attacker had spared him left Kakashi without an answer.
- Hyuga Kagami remained certain that Obito had attacked Kakashi but chose not to reveal his identity, fearing other ninja villages would use the revelation against Konoha.
