Hiei vs Riku
( Yu Yu Hakusho vs Kingdom Hearts)
Wiz: Jaganshi Hiei.
Boomstick: Riku.
Boomstick: Two badass swordsmen with power beyond anything you could imagine. These two legendary fighters are known for incredible speed and skills
Wiz: They both at one point were the villains of the story. Going along a dark path to reach their goals. But the hero showed them the errors of their ways causing them to regret their actions. They are now looking for redemption through their actions. We are to see which of these two anti-heroes are stronger.
Wiz: And it's our job to analyze their armor, weapons, and skills to find out who would win a DEATH BATTLE!
Backstory:
Wiz: Hiei was born a male fire demon in a female ice demon village. Naturally, the ice maiden weren't too thrilled about having a fire demon in their village.
Boomstick: So they decided that the best thing to do in that situation was to throw the small child off a cliff. Yeah these people are kind of messed up,
Wiz: Hiei was thought dead for years by the village. Little did the ice maidens know of his survival, and resulting in his new cutthroat nature.
Boomstick: Fortunately, as most popular anti heroes do, Hiei reformed after getting his ass kicked by the main character, Yusuke Urameshi.
Wiz:After years of travelling and aiding Team Urameshi, a group of fighters out to protect the three realms, Hiei grew to tolerate most humans, and helped save the world from those who sought to destroy its inhabitants.
Feats:
Wiz: Hiei was an incredibly skilled even from an early age, he had achieved A class status at the age of 5 far surpassing most demons in power. As he grew older, he killed several people mostly just for fun, causing those that survived to greatly fear and reject him
Boomstick: I mean wow that's one terrifying little child and he only gets more terrifying as he grows up. He would have defeated Yusuke in their first encounter if not for Kurama's timely interference.
Wiz: Even people who can evolve to become immune to Hiei's abilities aren't safe. For example Hiei defeated Zeru handily in a fight despite Zeru's ability to evolve and become immune to Hiei's fire abilities and sword. He even later learns to control Dragon of the Darkness Flame and absorb it leading to him being able to completely overpower Bui in a fight.
Boomstick: And that's before he was trained by Mukuro one of the strongest S class demons, who trained Hiei to become an S Class demon himself. At that point Hiei was strong enough to kill his old mentor Shigure.
Physicality: Strength
Wiz: Hiei is incredible strong. He easily killed Makintaro a C-class demon which is impressive considering Byakko another C-class demon could survive being pushed into lava.
Boomstick: That is one terrifying kid for sure, even without his sword. Hiei is still strong enough to lift a giant pillar with ease and even catch a giant axe that was thrown right at him. ThatWow what kind of training did this guy go through?
Wiz: He even consistently stalemates Yusuke in their fights which is impressive considering. Yusuke could knock out a world class boxer with just shockwave from his punch. And this was just a third of Yusuke's power. He even destroyed half of the dark tournament arena with his raw power.
Physicality: Speed
Wiz: Hiei is renowned across the world for his speed. He is by far the fastest person out of all Team Yusuke and considering his competition for example Yusuke who is fast enough to dodge gunfire and lightning arrows that's quite incredible
Boomstick: This guy moved fast enough to slice Seiryu sixteen times within just a second, move fast enough to the point it looked like he was teleporting and move fast enough to leave afterimages. And those are just feats from the beginning of series.
Wiz: Later on He quickly cuts off Makintaro's arm off and takes it for himself so fast that no one not even Makintaro noticed the attack until Hiei even move from the spot.
Boomstick: Once he and the rest of Team Yusuke finished a mission in 0.84 seconds. That's pretty amazing.
Blitzes Yusuke with afterimages
Dodges a point-blank Spirit Gun
Blitzes Seiryu, a demon who can throw hundreds of punches in a split second
Slices him sixteen times within a second
Sliced off Makintaro's arm without him noticing
Saves Yusuke from an explosion
Matches Yusuke in speed as well
With the rest of Team Urameshi, completes a mission in 0.84 seconds
Physicality: Durability
Wiz: Hiei is also incredibly durable, he was strong enough as a baby to survive falling from the sky to the ground.
Boomstick: I mean HOLY SHIT! This guy is just constantly shaking off fatal wounds as if they were nothing. Kuro biting him in the shoulder with his large fangs. Hiei just brushes it off. Zeru burning a hole in his chest, Hiei doesn't even look bothered by it and just casually regenerates the wound. Shigure cutting off his frickin' arm, Hiei just gets back up and keeps fighting as if nothing happened. Can anything kill this guy?
Wiz: Its true Hiei has shown that he has immense endurance and durability. You would be wise not to underestimate this deadly swordsman.
Survived a fall from the sky as a baby
Tanked a punch from Yusuke
Took a bite from Kuro
Continues to fight after losing an arm
Was fine after being struck by Kuro
Survived Zeru's fiery punches
Tanks a punch from Bui
He survived being hit by Mukuro who is said to hit with the force of a nuke
Spirit Classes:
Wiz: There are three worlds in the YYH Universe. Spirit World, Human World, Demon World, and Nether World.
Boomstick: In Spirit World there dwells many demons and apparitions. All are ranked by Spirit World from weakest to strongest, so Spirit World knows how to fight them or if they should leave the job to someone stronger.
Wiz: These are called Strength Ratings. They are rated based off of You-ki and Rei-ki, which have effects on physical and inner strength. It goes from D-Class to S-Class, S being the strongest, D being the weakest. SABCD. All have Middle Tiers within the letter tiers. If we see a strong D-Class Demon, the next C-Class we see is better. It's like the Mysterious Being Threat Level from OPM. Destructive capability is only listed when necessary and notable.

Skills:
Wiz: Hiei is a master swordsman. His teacher was Shigure, an S class demon who taught Hiei how to become adept in swordsmanship. He later on left to pursue his own goals and developed his own sword style along the way.

The Power of Darkness | Death Battle by DogDays11, Apr 22, 2018, 8:25:42 PM Literature / Fan Fiction / Fantasy
Wiz: Alright. The combatants are SET once again! Let's end this debate once and for all!
Boomstick: It's time for a DEATH BATTLE!
Makai Realm
A boy with spiky black hair that has blue outlining and white streaks. He wears a long black cloak-like jacket with a white collar. He had black pants, a red belt and a katana at his hip. He also had black martial arts shoes with white shins tucked into it was patrolling in the makai world for humans. This boy was Hiei.
'I wonder how Yusuke and the others are doing' the boy thought to himself. As he wandered around looking for humans. He stopped in surprise as he saw several small black creatures materialise out of the ground. 'A new type of demon' He contemplated as he readied his sword for the inevitable fight. The black creatures rushed towards him only for them all to be torn apart by Hiei's high speed slashes. Just when Hiei began to relax. A new threat showed itself as a shockwave nearly knocked him over from his right side. Hiel looked to the right and saw a portal.
"What the hell" He jumped back in surprise. Recovering his wits, he decided to investigate the strange occurrence, he walks towards it. From the portal came out a silver haired young man in a black cloak. He had mildly tanned skin, golden eyes, and silver hair with four bangs framing his face. He was also wearing black gloves and shoes. If Hiei didn't know better, he might have mistaken him for Raizen, the demon king himself. Same silver hair, Same sadistic look in their eyes and that insane amount of demonic power rolling off this newcomer, it was like this was long lost child of Raizen. Hiei was frozen in shock.
"My, my, why do you look so frightened? Were those heartless that terrifying for you" The man mocked. "Heartless?! What do you mean" He said shocked. That wasn't a type of demon he had heard of. This man was sending shivers down his spine. He wanted answers and he wanted them now! The stranger simply laughed at his confusion. Hiei growled sick of being mocked by this silver haired asshole, he decided to put an end to the talk and rush with a barrage of punches. His opponent to his surprise swiftly dodged all of his punches gracefully moving from side to side before jumping back out of his range.
'He is taunting me. Calm down, think rationally. I'm facing an unknown enemy, acting recklessly will just get me killed'' He pondered as Hiei got ready to attack.
He took out his sword and quickly flash stepped behind him then blitzed him before he could react with several sword strikes within a second. Hiei smirked at his enemy only to find out that their body was see through and seemed to be fading, 'Why is his body disappearing, its almost like its an afterimage!?' He realised too late that he only cut through an afterimage as he was hit by cold sensation before his body was frozen in ice up to his head. He looked down below to see that he was being sucked into the ground by some kind of black portal on the floor. As he looked back up he saw his enemy walk towards him looking smug at his supposed victory.
"How disappointing I didn't think you of all people would be tricked by a simple afterimage, it seems the rumours of your legendary speed and skill are greatly exaggerated." He said mockingly. Hiei could only snarl back at him as he felt humiliated by his blunder in underestimating his opponent. 'This is same kind of thing I used to mock my opponents for doing. When did I become so conceited' He pondered. The last thing he heard was the man say "Let's see if you can at least be a useful tool for the organisation." as he found himself completely sucked into the dark portal.
Realm of Darkness
Two people were walking through the realm of darkness looking for something in the dark realm.
The first was a white haired boy wearing a white, black-trimmed zip-up vest with yellow lining on the sides and a black high collar. He also has a pair of black wristbands, white-blue pants with a black belt with a silver buckle, and white shoes with black laces and a yellow lining on the bottom just above the black soles. This boy was none other than Riku.
The second was an anthropomorphic mouse with black fur, round ears of the same color, and a thin, long, black tail. The fur on his face is cream-colored. He was wearing a short-sleeved jacket with white lining. The top half of this jacket is black, while the bottom half is red, and there are two yellow straps dangling in front of it. His pants are red and sport a zipper going down the front of each leg. Each leg also has a yellow pouch with a black strap that partially cover the zipper, as well as a blue strap on the outer side of each pant leg. He wears very large, yellow shoes with grey backs and two orange, intersecting straps attached to the front of each shoe. This was the well known keyblade master, King Mickey.
They heard someone yelling before they crashed. "I'll go see what that was, you keep looking for Aqua." Riku told him companion. "Okay be careful" Mickey agreed. Riku headed towards the crash site, he gasped when he was a boy in a dark jacket like the dark cloaks of the Organisation. He saw the boy getting up. He decided to finish this quickly before this organisation member could jeopardise their mission. He lunged straight at him and slashed straight at his neck only to find out that he only slashed through a black cloak.
"You better watch yourself ningen, I am in no mood for your foolishness!" He heard someone shout angrily behind him. 'Ningen?' Sounds like something he heard Hades mumble to himself a few times when he was annoyed at him and Maleficent. Riku turned around and saw the boy in the dark clothes he tried to attack earlier. He was glaring right at him but how did he move so fast. Thinking back on it, he hasn't seen this newcomer before. Was he a new member?
"I won't allow you to get in the way, I'm going to get rid of you here and now" He yelled at the newcomer.
"Don't say i didn't warn you human, you just sealed your fate" Hiei replied
Fight!
The two began charging towards each other as they clashed.
Hiei struck first, he swung his sword towards Riku's neck, aiming to behead him immediately. Riku narrowly dodged to the right and proceeded to respond with swinging his own sword at Hiei. But Hiei already saw it coming and flash stepped behind Riku lashing out at him with sword strike to his back. Cutting straight through his afterimage. As Riku materialised behind him, his hand glowing with flames.
"Dark Firaga" Riku thrusted his hand out at Hiei unleashing a dark fireball straight towards him.
Hiei turned around and slashed the fireball apart. But Riku was already heading towards him thrusting his sword at his heart. 'Predictable' Hiei thought as he casually jumped on Riku's blade, lashing out with a kick towards his surprised face sending Riku flying back. "Did you really think that such an old trick would work on me" he mocked as he landed from his kick. Riku rolled around a few times before he stabbed his blade into the ground to stop himself. He body-flickered behind Hiei and threw a punch towards Hiei which Hiei ducked under before turning around and retaliating with roundhouse kick knocking Riku flying towards into stone pillar.
Hiei jumped towards him going for the knockout punch but Riku barely got his blade to block the attack. Hiei quickly grabbed Riku's face and threw him towards a wall on the other side. He then pummeled Riku with several punches before he could recover. Riku quickly raised his keyblade and used Aerial Slam to knock Hiei into the air. He jumped up towards him to continue the combo but Hiei quickly blocked his attack with his sword to stop him knocking them both away from each other.
Hiei still smiled at him before putting his sword away and taunting him with the classic "come on" gesture. Riku angrily charged towards him and threw his sword at him in a strike raid. Hiei narrowly avoided before going for a right hand jab on Riku knocking him back. Hiei proceeded to knee Riku in the face then went for a low sweep kick taking Riku's legs out but Riku quickly backflipped out of the way. Riku felt the aura of Flowmotion engulf him as he started the counterattack. He quickly stabbed Hiei in the chest before he could react. Then sent him flying with powered up right hand jab.
Hiei recovered midair and flipped in Riku's direction to throw a fireball at him. Riku slashed apart the fireball to find Hiei behind him aiming at his neck with his sword. Riku teleported out of the way before activating Bladecharge and heading back towards the black haired nuisance. Riku reached him and went straight for wide slash across his stomach only to hit an afterimage as Hiei materialised behind him and stabbed him in the chest before letting him fall.
Hiei simply spat out a glob of blood. "All bark and no bite, did you really think a couple of magic tricks would give you the win" Hiei taunted as he walked away believing his opponent defeated. 'Arrogant little brat, well then let's see how deal with this trick then' Riku thought as he wiped the spit off his face and got back up. He raised his keyblade up in the air
"Blackout" A dark mist shot out of keyblade in all directions hitting Hiei before he could react.
Hiei stumbled back and opened his eyes to realise he couldn't see. Unfortunately Riku took advantage of the moment and ran straight towards him slashing him several times with his sword. Hiei fell to his knees in pain. 'Calm yourself and relax. If I cannot use my eyes. Then i will focus on my other senses' Hiei planned as he focused on his hearing. Listening out for the vibrations of Riku's movements, the tensing of his legs.'There'
Hiei blocked Riku's attack and quickly counter-attacked hitting Riku's thigh. Riku stumbled back as he was bleeding out of his leg but he quickly recovered and jumped back before Hiei could deliver the finishing blow to his neck.
"Cure" Riku quickly healed himself before Hiei could take advantage of his injury. Hiei soon regained his sight and gazed at Riku with scrutiny. "I'll admit I wasn't expecting that but don't get too cocky just yet" Hiei said
"Sword of the Darkness Flames". Suddenly dark flames started to burn around his sword covering it completely.
Hiei then disappeared, moving at a much faster speed than before catching Riku off guard and slashing him in the chest several times at high speed before showing up behind Riku.
Riku coughed out blood in surprise as his chest was suddenly cut open with warm blood falling down from the large slash wound Hiei left on his chest, numerous smaller slash wounds over his body and the dark flames burning Riku's skin. Riku rolled around trying to put the fire out. As he stifled a silent scream from the agonizing pain.
"I warned you human, not to test my patience. Consider this your punishment" Hiei scolded him as he turned around and walked away.
"Wait" Hiei heard from behind him and stared at where there should have been a burning corpse. Only to find Riku slowly getting up, still bleeding from his numerous injuries with the most noticeable one being large gaping hole in his shirt showing where he had been deeply wounded on his chest. He wiped the blood from his mouth as he finally stood up
"I'm not done just yet" Riku told Hiei. "How did you survive that and how did you get rid of the flames" Hiei asked Riku in surprise. "Blizzard magic, it's quite useful for dealing for pesky flames like that" Riku answered. "Heh, seems you weren't a complete pushover. But be warned, i've barely even used a fraction of my power up to now. If you continue with this foolishness, I won't hold back" Hiei said as he powered up with a demonic aura around him causing shockwaves across the ground
"That's fine" Riku replied confidently as he smirked. His body glowing with his own dark aura. "I've just finished getting my second wind"
"Dark Aura"
Hiei and Riku both vanished and reappeared again clashing swords at blinding speeds, then they both disappeared again as they clashed swords several times all over the place at incredible speeds in the blink of an eye. Hiei quickly dashed behind Riku as he swung his sword aiming for a fatal blow. Riku moved out of the way at hypersonic speeds. He reappeared in the air, sword raised behind him and shouted.
"Spark Dive" As he dived down towards Hiei from the air, lightning sparks trailing from his body as he smashed into the ground. Hiei quickly jumped out of the way but was still stunned by the electric shockwave which left him staggering back. While Hiei dodged the initial impact. The electricity from the attack still caught him off guard shocking him, numbing his muscles and shocking him painfully as thousands of volts shocked his body. Riku raised up his keyblade as it lit up with bright flames. Aimed straight at Hiei.
"Mega Flare" A massive conflagration of flames headed straight for Hiei. It hit him head on while he was still being electrocuted. The entire landscape for miles lit up in an inferno destroying several hills and mountains in the realm of darkness. Leaving behind a 500 foot crater in diameter and large amount of smokes & flames engulfing the entire area.
Riku slowly walked towards the impact zone, checking to see if he had managed to finish off his enemy. However he saw someone slowly walk out of the crater. It was Hiei but with no sword. 'Must have dropped it after being hit with the Mega Flare'. His entire body was covered with wounds and third degree burns. His entire body looked like it had been through the grinder. Hiei only smirked as if his massive amount of injuries and burns were just minor setbacks rather than fatal injuries.
"I'll admit that you are strong ningen but this isn't over yet" Hiei acknowledged with a smile "You're going to have to do better than that to put me down"
"Fist of the Mortal Flame"
Hiei set his fists aflame getting ready for round 2. He charged towards Riku with burning fists trying to rush him. 'He is much slower' Riku noticed as he swiftly dodged all of Hiei's attacks with ease. Riku hit him across the cheek with the pommel of his sword staggering him back before jumping into the air and coming back down for a hammerblow. His sword wrapped in ice
"Blizzard Edge" He swung his sword down Hiei's chest. As Hiei's body was frozen over in an ice cube. Riku stared at the frozen Hiei. Happy to see that smug idiot finally put in his place and turned around to look for Mickey but before he could leave, the ice quickly began to melt to Riku's surprise. Riku jumped back as ice finally melted into a puddle surrounding a furious Hiei who was blazing with anger. Hiei's hand lit up as he glared at Riku.
"Flamethrower" The flames jumped out of Hiei's hands soaring towards Riku with a bright flare.
"Prism Windmill" Riku simply ran towards the fireball spinning his keyblade in his hands like a rotor and hit the fireball with dissipating the flames.
"Thunder Dash" Riku wrapped his body in electricity as he leaped toward Hiei slashing him with sword coated in lightning as he passed over him. Hiei looked like he was having a seizure as stumbled around trying to calm his electrified body while Riku looked at his clear discomfort and decided to finish it as he threw another fireball at him. Watching the fireworks explode as he sat on a rock.
Hiei walked out of the cloud of smoke even more injured than before looking incensed but he stopped and started strangely enough smiling as if he had something up his sleeve taking Riku off guard as Hiei brushed himself off.
"As a reward for such a fun battle, allow me to show you my own ultimate technique" Hiei said confidently
Hiei removed the cloth around his forehead, revealing his Jagan Eye.
'What is that thing!?' Riku thought shocked at the giant eye suddenly protruding from his opponent's forehead.
Hiei then proceeded to remove his sealing cloth which was wrapped around his right arm. Then he powered up again unleashing black flames around him. He concentrated focusing the black flames into his right hand getting ready to use his ultimate technique which was shaking apart the battlefield itself with just the shockwaves emanating from Hiei's power.
"I hope you are prepared for this because this is my strongest technique. Very few people have survived it" He thrusted out his arm as he called out his special technique
"Dragon of the Darkness Flame"
Black flames soared out from Hiei's hand forming a Chinese Dragon of Black Flames that roared with immense power as it headed towards Riku aiming to burn him down to ashes. The ground shook and broke apart beneath Riku's feet. Riku had just moments to defend himself as the dragon closed in on him. Riku's concentrated all his power into a powerful barrier.
"Reflega"
A grid of hexagonal squares formed barrier of light around Riku as he focused all of his power into deflecting the attack. His barrier shuddered under the dragon's power as it tried to stay together under the Dragon's enormous power. But eventually Riku managed to just barely deflect the Dragon back at Hiei.
Hiei however only smirked as he stood still and let the dragon consume him. Except he wasn't burning instead he seemed to be absorbing the dragon's power for himself. Growing stronger from it. Riku was completely overtaken by fear as he watched Hiei glow with ephemeral power that seemed out of this world. .
"So ningen what would you like to be written on your epitaph"
Riku looked at him shaking in fear, getting ready to give up as Hiei walked slowly towards him with an poised stride. He looked so completely certain in his own victory. That Riku knew in that moment for sure that whoever this was, it was no mere human. No human could look that terrifying. Hiei summoned black flames into his hand again but much stronger and even more powerful than before. He was furious. He figured he was about ready to just finish this debacle and destroy this ningen who dared to challenge his might.
Riku was about to give up when he remembered Aqua. The woman who had saved his life and sacrificed herself to save his life. He couldn't let her down. He couldn't fall here. He clenched his teeth, got back on his feet and got ready to fight back. There was no way in hell he would fail here. He couldn't afford to lose here.
Hiei stopped walking towards him as he noticed Riku's new resolve when he stopped shaking.
"Looks like you found your resolve.. Good it would be boring if this fight ended with you dying so pathetically".
Riku leaped towards him, his blade howling through the air as he brought it down on Hiei. Hiei managed to dodge and counter attack. Riku parried his attack and gathered wind into his right hand.
"Aeroga" Riku sent a tornado of wind straight at Hiei knocking him through a series of half destroyed pillars. Riku ran after him jumping into the air.
"Poison Dive" Riku dived down aiming to impale Hiei on his sword but Hiei barely managed to get out of the way in time. After he rolled away Hiei tried to get back up but found himself struggling to do the simple task as a foreign sensation overtook his body. 'Poison' Hiei figured just a moment too late. As Riku prepared to barrage Hiei with several spells.
"Bind" Hiei felt his body stiffen and limbs lock down.
"Confuse" Suddenly the world turned upside down for Hiei as he couldn't even tell what was up and what was down anymore.
"Zero Graviza" And now he was floating chaotically in midair against his will. Hiei figured this just his idea.
"Slow" But worst of all, Hiei felt. Was this moment where he felt like he was going through molasses with how pitifully slowly his body was moving even in the air.
"Blizzard" And Hiei knew no more as he was completely frozen in giant cube
Riku prepared to finish the job as he got into familiar stance for one final strike!
"Zantetsuken"
Riku moved faster than ever before as he slashed through Hiei at lightning fast speeds. The ice broke apart to reveal a fatally injured Hiei with one massive gash across his chest oozing out massive amounts of blood. Riku walked towards him making sure this time that Hiei wasn't getting back up. When he saw broken sword and body, not even twitching. He was certain that Hiei wasn't going to be moving anytime soon. Riku turned around and walked away.
When suddenly he heard the sounds of someone coughing. Hiei by some miracle was slowing getting back despite being covered in his own blood, having fatal injuries all over him. He was still rearing to fight.
"Crap like this is why i hate ninjas, All those damn magic tricks." Hiei snarled but he coughed again before he said "But I must admit i'm impressed that a mere human managed to push me this far, for a human to ascent to the level of top ranked S class demon is amazing beyond word. Tell me stranger what is your name".
"My name is Riku, Keyblade Master and Guardian of the Light" Riku responded.
Hiei nodded and replied "Well then, Keyblade Master, My name is Hiei, S class demon, the Flying Shadow. Now witness my true power".
Hiei transformed once more. His muscles expanded, his very skin turned green, his sclera turned yellow like a shadow with his iris turned a dark red, he even had giant eyeballs all over his chest and back. If Riku didn't know any better he would think Hiei became a heartless. He was tempted to fall into despair at this new transformation. But he wouldn't let it happen again. He already overcame Hiei's power once, he could do it again.
Hiei summoned black flames around his fists once again as he once more attacked Riku. Riku dashed behind him and charged his hand with electricity.
"Triple Plasma" Three bolts of electricity soared from Riku's hand into Hiei's back jolting him once more. Hiei struggled to endure the pain but kept staggering. Riku simply raised his hand into air.
"Meteor" A giant meteor came out of the sky from above soaring towards Hiei from above. Hiei looked on in fear as he couldn't move. The big meteor smashed into Hiei head on creating a large explosion sending shockwaves everywhere destroying the ground and surrounding landscape.
When the smoke and dust finally cleared away. Riku saw a scene of complete destruction, craters and fissures everywhere as if a cataclysm had hit this place and a heavily wounded monster barely breathing on the ground. Riku almost felt sorry for Hiei as he thought he may overdone it this time.
But once again Hiei just barely managed to drag his heavily wounded body back up as Riku wondered what kind of training Hiei went through to survive such conditions. But he was suddenly surrounded by red glowing ropes that curled around his body as he was caught by the Jagan Binding Curse.
"My Turn" Riku heard a furious growl as Hiei once more turned his hand covered in black flames towards him.
"Black Dragon Wave"
Several Black Dragons came at Riku aiming to devour him and Riku could do nothing but watch as they swallowed him whole. Hiei fell over as the area exploded in black flames demolishing whatever remained of the landscape.
Hiei soon his neck grabbed as his back pierced by a very familiar looking sword.
"How…"
A few minutes earlier...
Before the black dragons caught Riku. Riku used Stop. Then used Dark Roll to melt into the shadows and escape the red ropes. Using vanish he turned invisible and waited for his opportunity. Time resumed as the Black Dragons attacked the area where he previously was with ravenous hunger.
Present time
Hiei got back up despite his aching body's protests to stay down.
"Let's finish this here and now with one final confrontation" Hiei paused to find and pick up his broken sword in a nearby crater, summoning flames from the broken end that materialised into a sword of flames.
They both gathered whatever strength they had left and charged towards each other swinging their swords for one final battle.
When the dust hit the ground. Hiei fell headless in puddle of his own blood and only Riku was left standing.
Conclusion:
While Hiei had the speed advantage, Riku had reacted similar speedsters before like Xemnas and Young Xehanort.
Hiei may have been stronger and more durable but Riku could easily wear him down using status ailments to slow him down and weaken him. Until eventually Riku could finish him off.
Hiei had more battle experience. But Riku has been fighting people like that all his life and winning. It's nothing new for him. Riku could pretty much counter anything Hiei could throw at him. Riku is pretty good at strategizing and thinking his way out of problems. He also had a lot of offense and defensive options so he had a lot of ways to plan for winning the battle.
Riku had more versatility so he had variety of ways to beat Hiei, most of which Hiei had no counter for. For example Mini which turns your enemy into miniature person the size of an insect. Hiei had no counter for this and Riku could easily crush him at that size.
