"Kill me."
Haku lay amid shattered ice, his long hair spread across the bridge deck, the spear tip before his throat without piercing his skin.
"Those who are of no use to Lord Zabuza have no value in existing."
Chiba looked at him, his foot still pinning the wrist capable of forming hand seals.
"Did you decide that yourself?"
"I lost."

The World Tree panel unfolded within Chiba's vision, its dim branches establishing a connection with Haku's chakra.

Three evolutionary paths lit up in turn. As long as the spear tip advanced another inch, the extraction could be completed from Haku's blood.
The ice-wood composite was closest to Haku's Kekkei Genkai.
