If you just shouted out the names of your attacks like a normal person, I wouldn't have to resort to such dirty tricks

Summary:

Classic mid-boss strategy

Karin figures out that Izanagi is time-based, rather than hit-based, and Danzo only has 60 seconds per eye on his body.  It’s sorta like a self-genjutsu, and while Izanagi is active Danzo can turn all attacks against him into an illusion while leaving his own attacks reality.  Each eye provides 60 seconds of cheating, after which the eye is closed forever.  In spite of Orochimaru’s experiments that extend Izanagi’s use, Danzo only has 5 x 60 seconds left (not counting his one-eyed snake *snicker*), and so elects to summon his mighty dream-eating tapir to finish Sasuke off and preserve some strength for use against Madara.

Stab him in the shoulder-face!

Although the summon immobilizes Susanoo, Sasuke just blows a fireball into Baku’s mouth and destroys the summon.  Susanoo then comically punches Danzo away resulting in the loss of another disposable Sharingan.  Hopefully this will help cut down on Sharingan inflation.  Anyway, Sasuke continues to strike hard and fast so that Danzo cannot cancel Izanagi to conserve chakra, and the two stab each other simultaneously.

Reaction:

Baku was kinda goofy, but seeing Danzo’s sleepy-shocked face was amusing.  I highly doubt either of them are even that badly wounded from the stabs at the end, since both are turned towards the side.  I’m sure Danzo has some more creepy Frankenstein powers in his other clothed body parts, and Sasuke always has the option of summoning Susanoo while he hooks up with and sucks on Karin to heal himself.

Also, I only just realized that Danzo’s head looks like a pineapple.
