*Crack*
Kakashi twisted sideways, just dodging the barely-a-blur of ice that flew at Gato.
Haku chased the ice in even more of a blur, the glint of fresh ice flying from his hands as first Gato, then the hired thugs, fell.
Haku caught the flash of terror in Gato's eyes before he fell, icy spikes flaring up to catch him in the frozen embrace of death. Good.
Those same spikes gently cradled Zabuza as the idiot who stabbed him ripped out the weapon in a futile attempt to prolong their own life.
Haku swung his hands, the icy shards at his fingertips flying to their marks even as a stray blade sunk deep into his arm.
He twisted, kicking that person back with a wide blade of ice severing their spine.
Another row of large spikes ripped through, simultaneously blocking another attack on Zabuza and killing the would-be attackers.
Haku coughed, grabbing the blade in his ribs and freezing it in place, whirling on the attacker and sending more icy shards flying.
He ducked another attack, pain lancing out from the blade in his lungs as ice lanced through the attacker's neck.
He spun, shards of ice flying from one hand and a blade of ice held in the other taking out more people.
Shuriken stabbed into Haku's back, and he whirled, ice flying in direct retaliation.
No-one hurts my family. Haku snarled, moving through the pain to take out the remaining thugs, his own and others' blood catching on the ice as his vision started to dim.
Haku stumbled toward Zabuza's still form, collapsing next to him as the world faded in and out.
"HAKU!" "That was pretty cool, 'ttebayo…" "Hn…"
The three Konoha Genin hovered around Haku, seemingly at a loss.
Haku coughed weakly, blood spraying the grass. "Th- ank- y-ou…"
"It's- it's okay, dattebayo…"
"Join- join the damn…"
"Hkhhh…"
Everything faded to nothingness.
