I Survived in Anbu to Become Super Kage

Danzo was sealed inside the Heavenly Pillar.

Yako drew a kunai, gathered his strength, dashed forward, and drove it viciously into the Heavenly Pillar.

Clang!

The kunai snapped.

"What a powerful ocular technique!"

Four root ninjas appeared using the Body Flicker Technique. The leader of the group had a pair of Sharingan visible through the eyeholes of his mask.

Seeing the broken kunai in Fox's hand, Uchiha Mizugiku said, "This is an ocular technique. Only the Sharingan can undo it. A kunai is useless."

Yako played along. "Then I'll leave it to you, Uchiha Mizugiku."

In truth, Yako could have used the Wood Dragon Technique to absorb the chakra from the Heavenly Pillar.
