"I wish to use the Eye of the Moon Plan to make a deal with you, Lord Aizen..."
As Black Zetsu's hoarse voice slowly settled into the silent palace, a faint smile flickered in Aizen's deep eyes. He smiled softly.

"That's right... just as you said, Lord Aizen..."
"The Infinite Tsukuyomi of the Eye of the Moon Plan requires the power of all the Tailed Beasts
