Katsuki and Izuku pov
Walking towards the defeated boy Tempus mockingly said „ you are nothing but a mere brute relying on nothing but physical strength and that sword of yours. I on the other hand wield the greatest power of all, Time. And you know what whoever controls time controls everything"
„ you have fought valiantly, dare I say you nearly defeated me bearer of the void veil. However this marks the end of our battle" the man with the astronaut helmet said, walking towards his seemingly defeated enemy holding his injured hand.
„ the Boss didn't give me any instructions to keep you alive so you'll die right here and now brat..." the chrono warden liftet his hand intending to finish Katsuki but then he saw something unexpected.
„ I will now claim you as the prize my master has wished for...." but stopping in his tracks the star harbinger saw some he had never witnessed before someone stood up after his black hole
Getting on his knees again the crimson eyed swordsman started to silently laugh and then whisper „ Whoever controls Time controls everything eh. I like that line I think I'll make it my own, and if you thought I'd ever give up your dead wrong " now completely standing up ‚ I'll never give up, I'll never let Izuku leave me In The dust,I'll be beside him if he likes it or not' Katsuki thought before blue energy with silver accents erupted out forming into the shape of a white tiger behind him, his eyes turning blue and his hair taking on the same shade of silver as in Aincrad.
An emotion less face stood in front of a masked one, Snow White eyes staring at the man in the mask. „ I truly thank you because of you my eyes have been opened. I now know what path I need to take to reach my goals" Izuku said before a burst of green and black energy started coming out of him and an emerald green Eastern dragon manifested from the energy.

Katsuki pov
‚ What the hell is that has he been hiding a power like that the entire time, the pressure he's releasing is almost on the level of the lieutenant' Tempus thought while taking a couple steps back looking at the spectacle in front of him with eyes filled with horror.
Energy enveloping his body and healing the wounds he received as if they never happened the panther mask slowly krumplig away under the pressure. Breathing out heavily Katsuki stated „ Now we'll see who controls everything" the energy being sucked into his body again he took of towards his enemy at a speed that the man could barely track. Appearing behind him the now blue eyed boy delivered a rib shattering kick on Tempus.
Flipping in the air the man was able to just barely catch himself on his feet, clutching his now broken ribs, before sending a barrage of small clock hands toward the boy. The silver haired boy however simply raised his hand and the same blue and silver energy was released from it and now enveloped the projectiles completely freezing them in the air.
„ It doesn't matter what you do with the power of time on my side you'll never beat me" the chrono warden yelled angrily before manifesting a time bubble on the clock hands, however it had no effect „ huh that's impossible every object moves at least a little and if I speed it up it should... unless... no" the man took a step back ‚ it can't be unless... he completely froze their temporal motion all together, b-but that's impossible he can't, it's impossible not even I am able to completely freeze time'.
Now trying even harder Tempus sent wave after wave of attack at the boy, but each and every time the attack stopped before hitting or he simply dogged everything at a speed barely visible to him.
„ I'm starting to get the hang of this, let's try something new" before releasing the energy again this time cracking the ground beneath him and then releasing two massive explosions from his hands propelling himself into the air. Now launching himself from wall to wall Katsuki had completely disappeared of Tempus radar, who was now looking confused in every direction not being able to perceive the blue eyed boy anymore.
Then appearing right behind him stood the silver haired boy completely motionless before delivering a huge explosion blow to the clock man's back sending him flying into a wall. Walking towards his blade he picked it up and then slowly walked towards the wall his enemy had just made a crater in.
„ What where you saying before, whoever controls time controls everything. Well now I'm in control of everything it seems" while holding Tempus chin aggressively and when he was about to scream freezing him it time.
„ Now no more evading death,you're done" Katsuki said before cleanly cutting of his head killing him. „ Human trash, you don't deserve to live. And you who's watching me don't you think you're being a bit rude" the blue eyed boy said looking behind him as his appearance changed back to the red and blonde he was used to.

„ Now then I suppose we should restart this fight, right nexus" Izuku stated emotionless with a bit of sass to it while releasing an enormous amount of energy. His left arm was still broken but slowly gaining strength back, so he sheathed his blade again and opened the menu. Tapping around a bit three swords appeared in the air before him then fell to the ground. One was the greatsword Katsuki used earlier today and the other were older versions of his own sword.
‚ What is that a game screen, no never mind that what's with this pressure he's releasing, it's as strong as my own, no it's surpassed me!" the star harbinger thought while gettin pushed back a bit from the sheer force.
Stomping on the ground he cracked the class floor tremors flying into the air seemingly levitating along with the three new swords, the white eyed boy then sucked the energy back into his body and unsheathed his main weapon again, pointing the tip towards Nexus.
„ Now then let's find out who is truly stronger you or me" Izuku stated calmly before sending the tremors directly towards his opponent. And following suit after with the other blades following him.
Not letting himself get intimidated by the boy the masked man erected a star dust shield and blocked the incoming attacks then replying „ very well i suppose we will, but don't think your win will come easily. I am still the lieutenant of this organization!" then using his gravity manipulation he simultaneously made himself float and increased the gravity on the tremors effectively taking them out of the battle.
„ I wasn't counting on it" Izuku said coming in for his neck but being blocked by a barrier. Not hesitating Nexus used his worm hole creation to make portals behind him redirecting the incoming attacks from the flying swords towards the green haired boy. Not being bothered by this the swordsman simply stopped their movement in place and cracked the barrier only for his foe to vanish into a portal.
Predicting the other opening of the portal he sent the greatsword towards it. Nexus however didn't come out of this portal instead opening tens of portals all across the room and appearing in the middle sending cosmic blast to each of the portals creating a loop of endlessly repeating motion.
Countering this Izuku foresaw the trajectory of each projectile and meanwhile sent his other blades at the star harbinger who tried to continue but soon couldn't maintain the enormous amount of cosmic energy he needed to sustain the portals. Now focusing on the flying swords he used his gravity manipulation to render them useless and fixed them to the ground.
Floating above directly in front of Izuku he asked „ what do you say about we finish this battle once one for all I'll release my strongest technique on you so prepare yourself. ‚ this will be my first time trying this but I don't seem to have another choice. First create a black hole and compress it to the right size then absorb the faint amount of positive cosmic energy into the black hole and assimilate it into the core to reverse the effect of the black hole' then the previously black orb turned into a bright white sphere emitting light in the most beautiful manner Izuku has ever seen. „ White hole" nexus exclaimed sending it towards his opponent.
„This marvelous manipulation of space truly a final technique befitting the harbinger of stars, now prepare because I intend to show what I am capable of" Izuku said before releasing his energy again and the energy dragon forming into existence before coiling itself around him, its snout beside his face. Silently commanding the dragon to open its mouth green lightning started to crackle an a green ball of energy formed from ripples in the air itself.
„ Now Emerald Distortion!"
The two spheres of spatial matter collided each fighting for dominance the White hole trying to push it back but the Emerald Orb not bugging and eventually shattering the ultimate technique of the star harbinger now flying straight towards him.
However before it could make contact a storm of feathers appeared taking the shape of a ball around Nexus and then hardening on impact. Holding out until the orb disappeared.
„ I hope you don't mind me interfering but if would be quite costly to lose my second in command you understand I'm sure" a presence made itself known. Landing on the ground beside the lieutenant. „ I thank you master I hope you can find it in your heart to forgive me for my failure" nexus asked bowing.
„Ban, so you decided to come after all" The green haired boy stated. " Don't shit yourself Nexus if I wanted you dead I wouldn't have intervened, but you fought well even if you lost i still need you. Now to you since you won this battle and didn't kill my subordinate I'm inclined to give you a gift and let you off this once but don't think I'll hesitate to kill you again. If you insist on intervening my plans again you die" he then turned around again before saying " there is your parting gift. The girl is the second daughter of the Ashford family if you need to know so enjoy your win and don't bother me again" then flying out the roof trapdoor with nexus leaving a two restraint kids behind, but the restraints soon faded away.
One was the purple haired girl who was still bleeding everywhere and the other was Katsuki with his blade on his back. The girl immediately running towards Izuku and hugged him while crying. His eyes now turning green again he asked " Kaachan what happened to you?".
" Ah I killed some freaky time guy and then bird for brains came and captured me, you weren't kidding when you said he was strong" Katsuki stated looking down ant his friend and the girl who was finally smiling. „ So don't you think we should do something about her wounds?" the crimson eyed boy asked.
„ Yeah we probably should" Izuku then went to his inventory to grab a potion but he saw how the girl was looking at his ring which he had kept on the entire battle to heal his injuries.
„you want it" he asked the girl who got a bit flustered and looked away but nodded nonetheless. Taking the ring of his finger and putting it on hers he said " but keep it safe ok" the girl looked at her finger in awe before nodding and saying a brief „Thank you" with her wounds starting to slowly but visibly healing.
„ You really gonna give that to her, Well I don't mind, just makes it easier for me to surpass you" Katsuki before walking off with his hand behind his head.
„ Yeah it just feels right to give it to her. Now let's go Kaachan" Izuku grabbing the hand of the girl who was a bit shorter than him and following his best friend.
