( Yuuki's POV )
Tsukiumi: Yuuki, I want you to fight me.
Today when I woke up Tsukiumi challenged me to a fight, she was not referring to the training we did every day.
Yuuki: Tsukiumi, you have a special reason for that.
Tsukiumi: Of course, you always hold back when we train and in the future, we will face enemies as strong as you, right?
Yuuki: yes, as strong as me, also some stronger than me.
Tsukiumi: I will be the strongest Sekirei and I will fight by your side against them, that's why I want to know the difference between us.
I look Tsukiumi in the eye and I see all her determination, when she looks at me like that I can't tell her no.
Yuuki: Okay, I want to see my new limit.
Tsukiumi smiles and nods in confirmation, we head to the dojo, if I'm going to fight seriously I need my two-handed great sword 'fusion sword'.
When I left the weapons room all my sekireis were sitting waiting for the fight to start, Kuno and Yashima were even holding first aid kits.
Tsukiumi: are you ready Yuuki?
Yuuki: almost, first I want to kiss you.
Tsukiumi: R-right, a fight without holding back.
Tsukiumi blushes for a few seconds before understanding what I mean.
I approach her and put my hand around her waist, while her chest is pressed against me I taste her lips.
Our wings spread, my right pupil turns vertical and I feel a surge of power, I continue hugging Tsukiumi and stroking her head, she seems to forget what we were about to do.
Mitsuki: Hey, are you guys going to fight or what?
Tsukiumi: *cough* of course ... Yuuki please take this seriously.
Mitsuki reminds Tsukiumi why we were here and she separates her head from my chest, I keep hugging Tsukiumi and she tries to start our fight but she makes no effort to separate herself from me.
After enjoying Tsukiumi's body, we part ways and my aura turns serious.
Tsukiumi: are you ready Yuuki?
My fusion sword is made up of six different swords, the main sword, a hollow sword, two back swords, and two side swords and for this fight, I separated the side swords and the back swords, in my right hand the main sword and in my left hand a backsword and the other swords float around me, I use "Lightning body" and a powerful burst of wind wraps my swords.
Yuuki: ok I am ready.
Tsukiumi: " Tide jewels "
Nine water spheres appear around Tsukiumi, she extends her right hand and one of the spheres moves in front of her.
Tsukiumi: I am ready too.
Yashima stands up and raises his right hand.
Yashima: ok, Ready... Go!.
Yuuki: let's Dance.
( Third person's POV )
Yuuki: " wind blades "
Tsukiumi: first jewel "water celebration"
When Yashima lowers his hand Yuuki swings all his swords creating five gusts of wind in a crescent moon shape to attack Tsukiumi and she creates a powerful jet of water aimed at Yuuki's head, He slams his right foot on the ground creating a large amount of ice in front of him and Tsukiumi creates a water shield with his second jewel, when the attacks connect, both defenses are destroyed blocking the vision of both.
Yuuki: " twin dragons "
Yuuki creates a "storm dragon" and an ice dragon with gravity spheres around it, Yuuki jumps up and creates gusts of wind on his feet to propel himself in midair and attack Tsukiumi from three different angles but she counters first.
Tsukiumi: third, fourth jewel "water arrow".
Each water jewel is stronger than the previous one and the water arrows that Tsukiumi uses destroy both Yuuki's dragons and change direction towards him like homing missiles, Yuuki repeatedly kicks the air to dodge the water arrows but her attack pattern keeps him away from Tsukiumi.
Yuuki frowns when he sees a smile on Tsukiumi's face in a medium and long-range battle she has the upper hand, The moment Yuuki touches the ground he drives towards Tsukiumi leaving cracks in the place where he landed and he uses his swords to deflect the water arrows.
Tsukiumi: eighth jewel "water sword".
Tsukiumi creates a water sword to defend herself and when Yuuki is in front of her, his swords quickly descend on Tsukiumi, and with its weight increasing by his control of gravity the impact caused the water to spread violently.
Yuuki's swords went through the middle of Tsukiumi's sword, if she had used less energy on it that would have been the end of the fight.
With a smile Yuuki attacks Tsukiumi repeatedly, She tries to get away from him and regain her advantage but Yuuki creates several ice swords that restrict her movement, Tsukiumi uses three of her jewels to create six geysers around her that prevent Yuuki from getting close and she gets enough time to prepare her next attack.
Tsukiumi: " this water represents my pledge purify the evil residing in my ashikabi "
When Yuuki hears Tsukiumi's norito he concentrates all his power on his next attack.
Tsukiumi: " Leviathan "
A massive water dragon with three long blades on its head and surrounded by water arrows are heading towards Yuuki as it destroys the ground in its path.
Yuuki: " Omnislash "
Yuuki performs a crossed slash that stops Tsukiumi's attack, Yuuki appears next to the other backsword, He dashed while cutting Leviathan from one side to the other and he stands by his side swords, Yuuki throws his sword into the air and with his side swords he throws two wind blades to the leviathan, Yuuki returns to his starting position, raises his right hand and catches his complete 'fusion sword' and with a powerful thrust, he releases all the wind concentrated on his sword, in the form of a laser that pierces the Leviathan and passing close enough to Tsukiumi's head to cut a bit of her hair and leave a hole in the wall behind her.
Yuuki: Victory.
Yuna: YUUKI!
//////////
( Yuuki's POV )
After explaining to Mom what we were doing and repairing the damage with Kuu's help she left me with a warning not to destroy the dojo again.
I left the house to buy some things and visit Uzume and Chiho, Tsukiumi accompanied me carrying a picnic basket and told me that she wanted to go somewhere with me.
The place Tsukiumi wanted to take me to was the same building where I saw her in my dreams, just as in my dream we were watching the sunset.
Tsukiumi: the sunset from here is beautiful.
I take Tsukiumi's hand and she rests her head on my shoulder and after enjoying the food she prepared, she gives me a lap pillow, Before returning home, Tsukiumi's expression turns serious, and begins to pat my head.
Tsukiumi: Yuuki... I want to promise you something, I will reach you, I will protect you and fight alongside you, I will be the strongest.
Yuuki: I know you will be.
Tsukiumi takes my hand and she seals her promise with a kiss.
