( Yuuki's POV )
All of us in the throne room had the ability to fly so the floor collapsing was no impediment to anyone, and with my new power released I rocketed towards the traveler Red, with my speed it seemed that he was being attacked by clones of me.
I was overwhelming his defenses until I found a soft spot and I could see that each blow made him more mentally tired, Red made some attempts to counterattack But I was too fast for him and when the crack in his defense appeared I threw a powerful punch that sent him flying through the hole in the wall he had created earlier.
The girls and I followed behind him, into the skies of the burning capital, as I thought Red was not going to be a pushover and when we changed the scene he was covered with a red aura and his power level rose again, Red raised his hand and lifted some buildings from the ground and threw them towards us.
The girls used their swords to cut those obstacles and when I had a line of fire I fired a powerful [Gran Rey Cero] attack but now Red didn't try to dodge or block, he took the attack with open arms, with his comment after receiving my first hit I thought he was someone who enjoyed taking damage but he actually had a plan.
He was able to contain my attack between his hands and at the same time he gathered all the materials he could and created some puppet birds, then he turned my attack into multiple energy spheres that he sealed inside the puppets, those things flew at us and I used [Elemental phalanx] to rain down energy swords on the traveler.
The two attacks collided and the sky filled with explosions, I flew through the explosions and Red did the same, our fists met in the middle but since I was using [ Boost X200 ] at that time, the shock wave created by our collision sent Red flying backward while I was just pushed back a little.
Saeko appeared behind where Red was flying and with a swift movement she cut off one of the traveler's arms, Chifiyu was not far behind her for a second attack but before she could get close Red released a 360 degree pushing force around him, The girls returned to my side and we had a moment of respite that Red broke when he let out a loud laugh..
Red: jeje... HAHAHA You know, before I didn't understand why the boss was so interested in you, but now I completely understand, I'm glad I came into this world.
The traveler put on an honest smile from ear to ear, as if this was the happiest moment of his life, his power reached its limits and I could feel danger approaching, not for me but for this world.
Yuuki: Sensei, Saeko, you guys leave, I'll take care of this, tell Matsu to create an isolated zone around us.
Saeko looked at me seriously for a moment before nodding and leaving the place after wishing me luck, at this point it was impossible to avoid the alteration of this world but the damage had to be contained, the traveler released all his power, his red aura grew thicker, and his hair stood up from his power.
Red: I didn't think I'd have to use this in this world.
Yuuki: ...same.
When I felt the change in the atmosphere I knew that Matsu had fulfilled my request, I stretched my arm out and released the seals on my powers, something I hadn't done since the incident at that god's temple, our powers grew to similar levels and the smile on Red's face only grew wider.
Energy particles gathered where his missing arm was and within seconds that arm had regenerated, then we collided again and we exchanged a frenzy of punches and kicks, we threw and smashed each other around with such power that the city and the ground crumbled around us.
With every blow we delivered and received our bodies shattered into pieces, Red was regenerating as fast as he could and my phoenix flames were working around the clock to keep me in one piece.
When nothing but the castle remained standing at the station we stood on the rubble of the city and we gathered our powers for a final attack.
Red: I think after eliminating you, I'm going to make this world my main home, for the memories.
Yuuki: I'm sorry to disappoint you, but this isn't how things will end.
Red raised his hand and unleashed a myriad of energy spheres, something that could level a continent.
Yuuki: [multiple] [dragon breath]
For me, an energy dragon was created behind me and in its mouth a powerful laser was created that mixed all the different energies inside me and hundreds of magic circles appeared in the sky from which dragon heads emerged charging the same attack, Red lowered his hand and the two attacks were fired, In front of me the only thing I could see were lasers destroying everything and digging deep into the ground leaving the station unrecognizable, and when that stopped what was left was a deep crater with a body at the bottom.
I jumped in there to investigate but what I found was the body of another hooded man, his body turned to dust and only the imitation divine pearl that he used to control the BETAs remained, I think the bodies were exchanged at the last minute, Red was very determined to finish this fight so he was probably teleported out of this world forcefully, there was no doubt that he was a heavy hitter that the Crimson Ravens did not want to lose.
I remained alert in case of another attack behind me but nothing happened, I guess they don't have many who could fill in for Red, I guess I'll call this a tie.
With the battle over I decided to use the power I had already released, I floated in the sky, raised my hand and a dark blue clock of light appeared, Just as the hands moved backwards, the city began to rebuild, literally turning back time to the moment before the attack, and not only the buildings, people too came back to life.
