Under Clan Head Jiancheng's guidance, Akaseki soon understood how to activate "Izanami"—but, just like "Izanagi," he could neither truly comprehend it nor practice it...
Akaseki also came to understand why Clan Elder Chizuru had been able to create a secret technique that allowed no margin for error and offered no opportunity to practice—it was essentially another application of "Izanagi"!
The requirements for learning "Izanami" also differed from those for "Izanagi."

Setsuna Uchiha had been the leader of the clansmen who had wanted to rebel against Konoha while
