Reima reinforces his entire body and silver sword with Armament Haki as Dracula shoots towards him, if the attack from earlier had actually hit him he'd be in dire straights right now.
The Vampire slashes its claws against at Reima, the attack way faster than any other Elder's had been before, Reima manages to deflect it but is unable to recover enough to deal with the other claw... He blinks behind the Vampire and stabs at its spine, the blade piercing his back before they burst into red mist and reform a few meters away.
There was a large wound on its chest from where Reima had stabbed it, but after it smokes for a moment it quickly seals itself, leaving behind unharmed flesh.
Dracula "Your silver amounts to nothing, you can only hunt our lesser kin... Tell me, have you ever manged to killed one of us?" they ask, not expecting an answer.
Reima snorts, "Yeah, I have. Morwenna, Roisin, and Mira to name a few." he states, readying his sword for another clash.
Dracula scowls, his beast-like face contorting in anger. "I know not who those fools are, but I see not lies in your words... Whatever you used to end them, I am sure it won't work on ME!" he shouts, roaring at Reima and causing shockwaves to shake the area.
Reima simply covers himself in Armament Haki, ignoring the strain and effort it takes to encompass his entire body... The waves do nothing against his spiritual armour, if he hadn't used it the attack would've likely only ruptured his ear drums, which his body can heal in a number of seconds.
*Flash!*
Reima appears in-front of the Vampire and slams his foot into it's mouth as it continues to roar, causing it to bite it's own tongue off. The creature is launched away and hits the same mountain it'd sent Reima through, another similarly sized hole to the last, causing the mountain to crumble in on itself due to the many collisions against it.
Reima retrieves the Staff of Manus and points it to the sky, manifesting hundreds of Crystal Souls spears which he ignites with Chaos Flames, sending them shooting towards the Vampire as it tries to recover.
Reima then blinks behind the Vampire after storing the Staff of Manus and retrieving a different weapons... The Staff of Morwenna. He commands it to hold the Vampire in place after enchanting it with Crystal Magic Weapon.
The hands shoot out and grab the Vampire as it tries to turn into mist to escape, the Crystal enchantment allowing them to grasp incorporeal entities. Reima blinks away as the barrage of Chaos Crystal Soul Spears slam into the target, their weak homing ability being enough to allow most to hit the Vampire.
When the spears collide with Dracula they pierce his flesh before exploding into thousands of tiny flaming crystal shards, utterly annihilating it's body.
The only thing left of Dracula is a fine bloody mist that lingers in the air, the hands aren't able to grasp it as it's not incorporeal, the particles of Dracula's flesh are just too small to actually grab onto.
The Staff of Morwenna reforms in his hand as he swaps it out for the Staff of Manus again, pointing it is the red mist and casting Soul Stream, light explodes from the staff shooting through the area and blanketing everything in light.
...
After the light fades Reima looks at what's left of Dracula, frowning when he notices the individual cells quickly reconstituting themselves.
Dracula "GRAAAAAAGGHHhHHHHH!" he screams as his head is rebuilt first, the rest of his body reconstructing itself so fast that to the average person it'd look instant.
Reima scowls, his attacks earlier had been some of the strongest he had... Without going above his "limit" obviously, he didn't plan on taking this fucker out with a suicide attack and knew he still needed to weaken them more if he was going to use the Dark Hand on them.
While Dracula is reconstructing his body Reima thrusts his hands forwards and opens a small portal... to the centre of the sun...
*BOOOOOOOOOOOOOOOOOOOM!*
The nuclear fission powering the son immediately causes a nuclear explosion to escape the portal, hitting Reima as he closes the portal. This was all he wanted from it, if it left it open any longer all life on the planet would have been eradicated.
Already everything in sight was set ablaze from the nano-second the portal had been open... Reima could hear explosions where the Nilfgaardian army was but ignored it, needing to focus on controlling the rampaging energy now contained within his body.
His skin was bulging as the energy tried to escape his body, but he continued to restrain and attempt to control it... Dracula was scared shitless by what'd just happened, his body had almost burned to ashes in the instant the portal was open, and his opponent was glowing brighter than the sun currently was.
Reima isn't even able to shout the trademark Dragon Ball move as he finally thrusts his hands forwards and unleashes the energy at his opponent as they try to escape.
A beam of pure light erupts from his hands with envelopes Dracula and brightly illuminates everything it passes, even the otherside of the world gets brighter due to this attack as it streaks across the sky, likely doing irreparable damage to the ozone layer...
Reima huffs in exhaustion as the attack ends... He himself had been blinded by it, but using Observation Haki he could sense what'd happened to Dracula... The entirety of their body had been broken down at the molecular level, leaving only a soul floating there, trying to retrieve it's individual atoms to recreate its body from the atmosphere...
Reima just blinks next to it while grabbing the soul with the Dark Hand, feeling like he could use a lie-down...
Ya, Reima probably should have not used the centre of the sun to power his attack... The surface wouldn't have burned everything in sight... I guess he just wanted to be dramatic about it?
