The Third Princess.

( Yuuki's POV )

When the attacks of the demon and mine collided, a curtain of steam was created, in my left hand I created a large sphere of spinning wind, and when the demon came out of the steam curtain I threw it right at its head, The wind was leaving deep gashes but it seems like the demon had a decent regeneration ability and tanked my attack, Then I created a giant fireball that exploded in his face when combined with my other attack.

*Roar*

The demon let out a hurt roar and I followed the attack with a leaping ax kick to his head, I used gravity control to increase my weight but again I ran into an invisible barrier, Being the general's summoned creature, the demon received the effects of his artifacts but everything has a limit and I was set on destroying this invisible barrier by the end of the fight.

When my kick connected with the barrier I was suspended in the air and the demon who had the size advantage grabbed my hands and stretched me trying to tear off my arms.

I returned the favor by activating my kagune, covering it with an aura of energy and cutting off one of the demon's arms with a powerful swing, The demon let me go and while I was putting my bones back into place the demon used a good amount of magical energy to grow a new arm.

Yuuki: Come on, I know you can do better than that.

I was excited to continue the fight but at that moment my powers began to get out of control, immediately a screen appeared next to me, Cesca noticed what was happening and she contacted me.

Cesca: Master, your energy levels are very erratic, you need to return to the ship.

Yuuki: damn just when things were getting good.

Cesca: I'll call some of the girls to take care of the demon for the moment.

///////////////

I teleported back to the ship where I spent a few minutes in a special room to calm my powers, I couldn't return to the battle immediately because I was called to the infirmary, where Princess Lucia and the emperor, Zephyrus Roa Regulus, were.

When I arrived at the place I saw that the emperor was back to full health, Yumina was there, as princess of Belfast she was representing the kingdom.

Lucia: Yuuki-sama.

The first to see me was Princess Lucia, I approached them and the emperor then grabbed my hand with both of his.

Zephyrus: Yuuki, I have no words to thank you for what you are doing and for saving my daughter.

Yuuki: all in a day's work, For both Belfast and Regulus, I can't let a power-hungry general start a war.

Yumina: hehe that's just how Yuuki is.

Yuuki: To finish things here I'm going to need help from you two.

Lucia: Tell me whatever you need Yuuki-sama.

Yuuki: You can just call me Yuuki, I need you to think clearly about your brother.

Lucia: uh ok Yuuki, y-you can call me Lu.

I pressed my forehead against hers and used [Recall] to see the image of her brother, to my surprise the random Knight I rescued was her older brother, the princess was blushing from our interaction but I put her aside for a moment, I asked Shizuka about the guy and she brought him where we were, The royal family was happy to have met but it was not yet time to celebrate, Next I needed the help of the emperor and for that, we moved to the control room, obviously they were surprised to see our view of the empire.

Zephyrus: what is this place?

Yuuki: my flying ship, the new thing in transportation, and I would love to talk more after the capital is safe.

Cesca half a report of the situation, the girls had stopped half of the army and were still progressing rapidly, the only problem was the demon, I wanted the emperor to give a message about the situation, tell the citizens to take refuge, and seeing the emperor safe would demoralize the enemy.

Yuuki: Cesca take care of things here, I'll go for my second round with the big guy.

Rosetta: Master, do you have some kind of plan?

Yuuki: uh not really.

I jumped off the ship and huge screens appeared in the sky of the capital with the message from the emperor, I moved to where the demon was and there I saw Barghest and Lilith keeping him busy, Barghest tanked a powerful blow that sent her flying, luckily I was there to catch her.

Yuuki: hey girls, backup has arrived.

Barghest: Yuuki, this guy just keeps regenerating, do you have a plan?

Yuuki: I'm not going to hold back this time.

I told the girls to stay behind and I faced the demon alone, it seemed that he recognized me because he let out another angry roar, To finish this in one fell swoop I released all my seals, transformed into my dragonewt form, and used [Boost] x20 to go all out, the air around me began to vibrate and when I shot myself at the demon I completely destroyed the roof beneath me, I hit the invisible barrier but this time I heard a loud crack, I broke past the barrier and my blow completely destroyed the demon's upper body.

As I promised Lu, I ended the coup in less than a day.

////////////////////

After the danger passes, I take charge of repairing the damage to the capital, we contact the King of Belfast and we meet to talk about the future.

Zephyrus: Thank you very much again for your help Yuuki, we would be lost without you, and I wish I could reward you appropriately.

Yuuki: Don't worry about that, this is a crucial moment for you, you need to clean house, rebuild your army, and replace all Bazoar's supporters, Being able to improve the relationship between both kingdoms is enough for me.

Zephyrus: Still, it doesn't feel like enough.

Tristwyn: haha I feel you, Yuuki has saved my life and done so much for my kingdom, I thought I could never repay him for that but at least he agreed to take my daughter as his fiancée.

Zephyrus: That solves it then, he should take Lucia too.

Tristwyn: That's not a bad idea, that will also deepen the bond between our kingdoms.

Yuuki: hey wait a minute.

Yumina: I also agree with this, I already spoke with Lu and she agrees.

Damn Yumina, you work too fast.

Yuuki: Lu, is that true?

Lucia: ah W-well, yes, if you would have me, I would be happy to be by your side.
