Itsuki (POV)
The waves in the water begin to rise more violently and boulders from the cliffsides begin to fall off di the the buildup of chakra going on right now between Akari and myself. Then in a single cloud to ground lightning strike, we take off at each other with speed not visible to the human eye. Our fists collide making the water separate around us and causing everything in the area to shake.

We trade super fast blows but neither one of us can land a decisive hit.

I finally land one by knocking her left out the way and hitting her in the gut with a right. She hunches over only to get met with my right knee. She gets hit and goes up but her tail wraps around my legs.
Itsuki (one tail)- What the?
The tail yanks back and causes me to fall back. As I fall back, Akari front flips in the air and she drives her heel straight into my skull and sends me underwater.
Itsuki *mind*- I got something for ass. Shadow Clone Jutsu!!
I spawn five clones underwater with me and we jump out and go for her. She cartwheels out of the way of the first three who divebomb towards her. As the rest us us lands, she jumps and drop kicks one in the face and it poofs. She then backflips over another and snaps his neck making it poof. Two of my clones come from beneath her in the water and grab her ankles.
Akari (second state)- What the?
The other clone takes her out atthe back of her kneecaps so she goes falling forward on her knees. The clone backflips away to create some distance and we line Akari up so that she's in the middle of us. We nod to each other and we both sprint at inhuman speeds and I connect with a superkick while my clone simultaneously hits her in the back of her head with a running knee.
Indigo: Basically this.

She crumpled like a leaf and doesn't move. The clone and begin to stomp her out. The clone grabs her by the arms and gets her up and holds her there with her arms trapped so she can't use them. In my right hand red lightning comes into existence as I form the crimson chidori. I run at Akari ready to end this fight. Right as I get to her, she kicks my hand away and drop kicks me away. I go back but I slid to a stop. I watch as Akari's tail goes underneath and behind the clone and stabs him through his neck making him poof.
Akari (second state)- Water Style: Giant Water Dragon Jutsu!!!
The water bubbles for a bit and out rises a dragon made of water.

Itsuki (one tail)- Oh really now? Two can play that game. Storm Style Secret Technique: Demon Dragon Storm!! Storm Style: Falling Phoenix Crusher!!!!
The Storm morphs into a dragon and a Phoenix made of lightning comes out of it too.

Both Phoenix and dragon fly to the dragon as the dragon dies the same to them. They meet head on and a massive explosion takes place.

I'm blasted back and I crash into the side of the cliff and fall back in the water. I try to get up but I'm smashed from above by falling boulders and I'm sent underneath. I could feel something else break inside of me but I ignore the pain and swim to the surface. My top half surfaces only to see a massive wave of fire headed my way.

Itsuki *mind*- That's Fire Style: Great Devastation. Shit.
The wave of fire hits me dead on and I'm burnt to a crisp.
Akari (POV)
After fire goes away, I see Itsuki floating face down in the water. I walk over to him a kneel down.
Akari (second state)- Itsuki? Can you hear me?
I move him but he doesn't respond. His chakra aura fades and I get more worried.
Akari (second state)- Itsuki?! Answer me darling please!
I feel him wrap one of his hands around my ankle and he slowly begins to move. He makes his way up to his knees by using me to help himself up. He looks at me with those wolf eyes of his.
Itsuki- I'm not giving up. You're gonna have to kill me.
I take his left hand off my waist and I take his ring and middle finger and snap then causing they to break.

He hollers in pain and I spartan kick him to the cliffside and onto solid ground. He still tries to get up go I climb up to the top of a boulder and I jump off of it and land on him and deliver a flip piledriver which buries his head and neck into the ground.

The rest of his body comes down and goes into into the water causing his head to be free. He floats to the middle of river motionless.
Dimension inside Itsuki
Seventeen tails (POV)
The boy's body lay motionless in front of our gate.
Head 2- You weak little insect. You better be grateful to my brother and I your the former Jinchūriki who sealed me inside a little bitch like you. Brother, let's do it.
Head 1- Yes sister.
Akari (POV)
As I clutch my beaten and broken body, I watch Itsuki who still lay motionless in the water. Suddenly that same seventeen tails chakra aura comes back around him. It lifts him up on his feet. He disappears and reappears in front of me, grabs me by my face and and smashes me into the rocks. I fall to the ground as I grab my my face and yell out in pain as blood gushes from my nose. I scramble away from Itsuki as he looks on at nothing. He clutches his stomach and he lets out an inhuman roar. His fangs get sharper as well as his fingernails and toenails. He lunges back onto the water and the chakra condenses into that wolf outline and this time, two demon chakra tails sprout from behind him. The water below him sizzles as he gets down on all fours.
Akari *mind*- You have got to be kidding me. Just what in the hell do I have to do to end this fight?
