During the war arc, when the infinite tsukyoumi was launched the only ones who got saved were team 7 ,obito and the Edo tensei hokages. The Edo tensei are invulnerable to genjutsu. How is that the most powerful genjutsu could not affect them but kotoamatsukami affected itachi when he was a Edo tensei ?. Is kotoamatsukami more potent than infinite tsukyoumi ? Could it control a senjutsu user or a rinnegan user ?
