Seelentau wrote: Yes, it was Izanagi. He still had both arms, so no cell replacement was used and Obito's Kamui doesn't work like that. More importantly, his suit is still intact. Izanagi simply writes off damage as a dream. Had he replaced his arm, it would've been visible.

I just checked the manga. It had to be Izanagi.
