The Anbu are Surprised!

Yuki hears it too. She gets in her Gentle Fist stance & activates her Byakugan.

Sasuke turned and activated sharingan.
He felt a chakra presence that made his eyes widen and he stumbled backwards.
''Oh crap....'' His eyes were wide.

"What?" she asked.

''IT is....Stronger.'' His eyes widened.
The curse mark thing began to come out from the ground. It had taken the form of Sasuke's shadow. It's eyes were almost like sharingans but had an X in the middle. Red eyes glowed and it looked almost like Sasuke. It had two, black crow like wings and a katana like Sasuke's that glowed with red energy.
''I'm back.'' It said cruelly.

"YOU!!!" she hissed.

Sasuke stared at it angrilly.
''Damn. And it's not just a shadow anymore.'' He said.
''It? Call me Curse.'' The curse mark demon said with a smirk.
''Yuki, it's practically breathing demon chakra. This thing is almost as powerfull as the nine tailed fox!'' He said.

'I'll help brat' said Shichibi as Yuki was covered in gray chakra. She grew seven gray chakra tails. "Alright you bug, feel the wrath of the Shichibi no Kaku" hissed the Shichibi Yuki.

Curse smirked.
''Time to finally face a bijuu. And I'm only in my second form. Heh heh this should be fun.'' Curse moved so fast nobody could see him and ran up, using the sword to backflip and use fireball jutsu at Yuki.
But it wasn't ordinary.
The fire was black and Sasuke's eyes widened.
''Shadow fire. That's what was used to stun the nine tails fox.''

Kaku slammed one of it's tails into the ground & a giant wall of earth & came up & blocked the fire. Kaku appeared behind Curse & shot mud projectiles at him but there was kunai hidden in the mud.

Curse grinned and threw something at Kaku. The stuff was grey and was soon turned to cement.
It caught up in the wings. And began to spread a poison.
''This should get you badger.'' He said.

Sasuke came up behind Curse with a chidori.
But Curse turned and kicked Sasuke into a tree. There was cracking sound as his head hit the trunk at 3000 mph.

"Sasuke" came Yuki's voice as Shichibi Yuki had bones come out of her like spikes. "Now it's personal. Dance of the Willow" she said as she slashed at Curse multiple times at an incredible speed, using incredibly acrobative spins to avoid any of Curse's possible attacks.

Curse was unprepared and went flying into the bushes. When he got up black blood came from his mouth and trailed to the ground.
''Heh, blood. Seems like you are vulnerable when Sasuke is hurt.''
He snapped a finger and suddenly Sasuke was being held from the neck, a gash in his head and slowly being choked.
''If you want him, go through me.'' He whacked Sasuke and another crack was heard.

She appeared behind him. "You are in my strike zone. Eight Trigrams Three Hundred Sixty-One Palms" she said. "2 palm, 4 palm, 8 palm, 16 palm, 32 palm, 64 palm, 128 palm, 256 palm, 360 palm, 361 palm" she said as she sped all around him, quickly attempting to close off every chakra point in his body & aimed the final one at his heart.

Name: Eight Trigrams Three Hundred Sixty-One Palms
Rank: -
Element: None
Description: This jutsu is considered the most powerful technique within the Hyuga clan, and is generally used as a last resort. When using this technique, the speed of the user is comparable to that of the Reverse Lotus. This jutsu allows the user to strike all 361 chakra points of the opponent, paralyzing them with each blow and instantly killing them upon the final hit.

''Interesting Hyuuga'' he said as he suddenly flew upwards with the wings and dropped Sasuke from 5000 feet high.
''Goodbye for now.'' He said and faded away.
Sasuke was falling and couldn't move.

She grew gray angel wings & caught Sasuke. She landed & gently laid Sasuke on the ground. Her wings, tails & gray chakra disappeared. "Sasuke, wake up" she whispered in his ear.

He wasn't waking. His pulse was getting worse and worse, stopping alot.

"Sasuke" she panicked as she examined the back of his head to see blood. She placed her hands on the wound & sent some of her chakra into the wound, healing it. She then did CPR on him, trying to wake him up.

Sasuke stayed silent, his wound healed but not awakening.

She couldn't think of anything to wake him up so she just gave him a deep kiss on the lips, hoping that would do the trick.

Sasuke had a faint blush and his eyes went wide. He jerked up fast.
''Wha-wha><''

"Looks like that did the trick. Welcome back Sasuke" she said with a smile.

His eye twitched a tad.
''What just happened??'' He asked confused.

"I couldn't think of anything of to wake you up so I kissed you, hoping that it would wake you up" she said.

The blush got deeper. Sasuke turned his head.
''W-well....What about Curse?'' He asked, changing the subject fast.

"The coward ran" she said.
