Back in Shinjuku, within the Hypnos headquarters were Henry, Terriermon, Impmon, Ai, Mako, Suzie, Lopmon, Kazu, Guardromon, Kenta, MarineAngemon, Ryo, Cyberdramon and Calumon, who all had trouble sleeping the other night, as they worried for the safety of their friends, but in the end, they all knew their leader, his gentle natured Digimon, the serious redhead and her ever loyal Digimon would never lose despite whatever the Champion Hunter had in store for them.

As Yamaki had instructed through Riley and Tally, the Hypnos network was able to get onto the frequency the Champion Hunter had used the day before to watch the outcome of Takato, Guilmon, Rika and Renamon's battle.

When the Tamers and their Digimon partners were taken to another one of the Champion Hunter's Death Zone Stadiums, immediately, Guilmon's eyes narrowed into slit shapes, as he got in front of Takato and began to snarl, while Renamon jumped in front of Rika and got into a protective stance, as on the other side of the arena was a man with swept back brown hair, with a strand hanging down his face, who was dressed in a white uniform, as a sword was adorned within his belt, however, what Takato, Guilmon, Rika and Renamon found more worrying than the man's blade was his menacing and manipulative eyes, as the human and Digimon pair knew, that their 'greatest evil' they had to face was truly a deadly opponent, Sōsuke Aizen.

Takato then pulled out his D-Power, before he then exclaimed. "Biomerge Activate!"

"Guilmon Biomerge to... Gallantmon!" Gallantmon announced, before Rika pulled out her D-Power and exclaimed in loud and determined tone. "Biomerge Activate!"

"Renamon Biomerge to... Sakuyamon!" Sakuyamon announced with the same amount of courage and strength Gallantmon had exclaimed before her, however, even with two Mega level Digimon against him, Aizen didn't show any sign of worry, which got on Rika's nerves.

"You think you're so cool, don't ya?" Sakuyamon questioned in an ill-tempered tone, before she leapt into the air and yelled out. "Well, let's see how cool you are after this!"

"Fox Drive!" Sakuyamon exclaimed, as the magical vixen fired a sphere made of mystical blue coloured fire from her Kongou Shakujou spear right at Aizen, who looked like he was consumed by the burning blast, however, a chill went up Sakuyamon's spine when a voice asked from behind her. "Is that all?"

Sakuyamon then turned her head to look into Aizen's malevolent eyes, before she cried out in pain as the former Leader of the Arrancar Army used his Zanpakutō, Kyōka Suigetsu, and sliced through her back.

"Sakuyamon!" Gallantmon called out in a highly concerned tone as Sakuyamon fell to the ground, but the spell-casting sorceress was fortunate enough as she was caught by Gallantmon, who then asked her in another tone, full of concern. "Sakuyamon, are you alright?"

"I've been better." Sakuyamon admitted, as she let out a groan of pain while getting to her feet, in which Gallantmon told her in a serious tone. "Sakuyamon, try to relax. I'll deal with him."

The Rika part of Sakuyamon was about to protest when she heard Gallantmon tell her what to do, but it was then she could see he was just trying to protect her and Renamon after suffering from such a powerful attack, in which the Mega level vixen nodded her head, before Gallantmon faced Aizen.

"Lightning Joust!" Gallantmon exclaimed, as he fired a powerful blast of energy at the from his Gram Lance right at Aizen, who in turn, simply held up his Zanpakutō, in which Gallantmon, Sakuyamon and everyone watching from the Hypnos headquarters were left speechless as Gallantmon's Lightning Joust was simply sliced in half the second it made contact with Kyōka Suigetsu, causing two smaller Lightning Joust blasts to travel past Aizen before they exploded in the background.

Gallantmon then charged at Aizen with all the speed he could muster, as his Gram lance was drawn forward, as Gallantmon planned to plunge his holy lance through Aizen's black heart, if he had one, but was shocked when the former Captain of the 5th Division was able to grab his lance, without so much as getting stabbed by the end, before Aizen performed a horizontal slash down Gallantmon's chest, which caused him to groan out in pain, but fortunately his armour was made of Holy Chrome Digizoid, otherwise Gallantmon would've been sliced to nothingness.

Gallantmon then managed to pull his Gram lance back from Aizen's hold, before he attempted to strike Aizen down, only this time, the traitor of the Soul Society protected himself with his Zanpakutō, before an epic battle between signature weapons began.

As Aizen blocked each of Gallantmon's strikes, he was moderately impressed how Gallantmon was wielding the lance like it was a sword, but knew if he wanted to get his revenge on Ichigo, the Soul Society and those back in his world, then he should stop toying around and kill Gallantmon and Sakuyamon, in which the wielder of Kyōka Suigetsu managed to forcefully plunge Gallantmon's Gram lance into the ground using his Zanpakutō, before he pulled Kyōka Suigetsu back and was about to stab into Gallantmon's chest.

"Gallantmon!" Everyone called out in a concerned tone back in the Hypnos headquarters, but were surprised as Gallantmon brought forth his Aegis shield and protected himself from Aizen's attack, but also got him into a position for a counterattack, as his shield was radiating with a powerful aura of energy.

"Shield of the Just!" Gallantmon exclaimed, before he unleashed all the energy he had stored within the shield from the very beginning of their battle, and fired a beam from his Aegis shield, which struck Aizen back and slammed the former Leader of the Arrancar Army into the wall behind him, creating a massive explosion.

However, as the dust cleared, Gallantmon, Sakuyamon and everyone was stunned to see Aizen had been harmed by Gallantmon's Shield of the Just attack, but had only sustained several marks across his outfit, while a small trail of blood fell down the left side of his mouth, in which he let out a small smirk.

"Fox Drive!" Sakuyamon then exclaimed, as the shaman Digimon jumped into the air and fired another sphere made of the same mystical blue coloured fire from her Kongou Shakujou spear right at Aizen, who effortlessly avoided the fiery attack, before the traitor of the Soul Society asked in an unimpressed tone, as Sakuyamon landed next to Gallantmon. "Is that all you can do?"

It was then everyone back at the Hypno headquarters watched as a dark sphere of energy, which was emitting a dark purple aura formed in Aizen's right hand, which they had no idea what it was, but from what they had seen, it was no doubt going to be trouble.

"Hadō number 90: Kurohitsugi." Aizen then said, as lines of dark purple formed a cube shape around Gallantmon and Sakuyamon, before darkness rose from the ground and trapped the pair within.

But it was then Aizen was confused when his Black Coffin attack dispersed, revealing Gallantmon, who had a few scratches across his body, as Sakuyamon was on her knees and breathing heavily.

"You are still alive?" Aizen questioned, in which Sakuyamon smirked, before the foxy enchantress told Aizen in a weak tone. "I... I used my Amethyst Mandala attack, which was able to purify your Hadō and render it useless before it did any serious damage to us."

"What an astounding technique." Aizen commented in a slightly impressed tone, before the former Captain of the 5th Division stated. "But it doesn't change the fact you will both die."

It was then before anyone back at the Hypno headquarters knew what happened, Aizen had appeared behind Gallantmon and Sakuyamon, in which they both collapsed onto their knees, before falling to the floor, as the traitor of the Soul Society had struck them both at such a speed, which they were unable to match, prepare for or defend themselves.

"Gallantmon! Sakuyamon!" All of the Tamers and their Digimon partners and friends called out in concern, but were relieved as they watched as Gallantmon weakly got to his feet and got into a defensive stance.

"Poor doomed thing you are still alive?" Aizen questioned, before the wielder of Kyōka Suigetsu told Gallantmon. "But it looks like the same can't be said about your little partner."

Upon hearing that, Gallantmon quickly turned his head and was shocked to see Sakuyamon lying on the ground, in which he made his way over to her and started to gently shake her. "Sakuyamon?"

However, Sakuyamon didn't respond, in which Gallantmon began to shake Sakuyamon harder and pleaded to her, as tears formed in the corner of his eyes. "Sakuyamon!? Wake up. Please wake up."

"Sakuyamon!" Gallantmon yelled out, as the cold facts had hit him that Rika and Renamon had been killed by Aizen, in which Gallantmon pulled Sakuyamon close to his body and hugged her tightly, before he gently lowered her, turned to the former Leader of the Arrancar Army, before Gallantmon yelled out in a tone of absolute rage, as he was engulfed in flames of darkness. "I swear I will make you pay! I swear even if it kills me, I'll tear you to pieces and destroy until there's nothing left of you!"

"Oh no. I think Takato and Guilmon are going to Dark Digivolve again." Henry stated in a worried tone.

"What!?" Kazu questioned in disbelief, before Impmon asked in a nervous tone. "You mean Megidramon's coming back?"

"Not Megidramon." Henry replied, before he said in a worried tone for Takato and Guilmon's wellbeing. "But something just as fearsome and deadly."

And Henry was right, as the flames died down, it looked as though the Dark Digivolution had failed as Gallantmon still stood in place, but upon closer inspection, everyone back at the Hypnos quarters could see Gallantmon's armour had changed from its regular and pure white to a dark gray, while his cape and the parts of his armour, shield and lance had turned duke blue, while his eyes were no longer the gentle, friendly and caring yellow of Guilmon's but were now a dark crimson, filled with hatred and revenge, in which Henry go out his D-Power to analyse Gallantmon's new form and told everyone the information contained about the dark side of Gallantmon. "ChaosGallantmon, a Virus Knight Digimon. Who carries out his own form of justice by eliminating all, regardless of innocence, with his Chaos Shot and Judecca Prison attacks!"

"Chaos Shot!" ChaosGallantmon exclaimed violently, in a mixture of Takato and Guilmon's enraged voices, as ChaosGallantmon fired a corrupted version of Gallantmon's Shield of the Just attack at Aizen, who quickly jumped into the air avoiding the attack, however, the wielder of Kyōka Suigetsu was shocked when ChaosGallantmon shot into the air and managed to stab him in the right side of his chest.

It was then ChaosGallantmon rose his Balmung spear into the air, with the wounded Aizen still pierced through it, before ChaosGallantmon threw his arm downward and slammed the traitor of the Soul Society into the ground, before ChaosGallantmon shot down.

"Cruel Balmung!" ChaosGallantmon exclaimed in fury, as he planned to strike Aizen using his evil spear, however, the former Captain of the 5th Division managed to get out of the way, but while Aizen was able to avoid ChaosGallantmon's Cruel Balmung attack, his arrogance made him an easy target, in which ChaosGallantmon removed his spear from the ground, before he charged into the traitor of the Soul Society with his Gorgon shield and slammed him between the wall and his shield, which was begging to fill with evil energy, in which ChaosGallantmon planned to destroy himself along with Aizen, as he had taken away the ones Takato and Guilmon loved.

However, ChaosGallantmon was confused when Aizen let out a small chuckle, which caused ChaosGallantmon to demand in an aggressive tone. "What's so funny?"

"What's funny is all this time did it not occur to you that you're fighting the wrong enemy?" Aizen simply replied, which confused ChaosGallantmon and caused him to question in confusion. "What are you talking about?"

"What I'm talking about is that it isn't my fault those you cared about died." Aizen told ChaosGallantmon, which angered him, before he demanded. "Then whose fault is it!?"

"Simple. It's yours." Aizen replied, as a small smirk appeared on his face.

"What are you talking about?" ChaosGallantmon questioned, in which Aizen told him. "Think about it, if you had been stronger then you could've stopped me, and I can tell that your human side is the side that caused all this pain."

-Within ChaosGallantmon's mind-

"He's right, Takato..." Guilmon, whose skin was black, while the markings on his body were dark red, making him BlackGuilmon, began to say, before he lunged at Takato and yelled out. "This is all your fault!"

"Rock Crusher!" BlackGuilmon roared out, as he slammed his claws into the ground, narrowly avoiding Takato, who in turn, called out to BlackGuilmon in a pleading tone. "Listen to me, boy. Aizen isn't telling the truth, he's messing with your head."

"Shut up!" BlackGuilmon snapped back, before he picked Takato up by the collar of his shirt and threw him across the room, as it seemed Aizen's power to manipulate the minds of others had gotten to Guilmon.

-Meanwhile, outside of ChaosGallantmon's mind-

Aizen watched in amusement as ChaosGallantmon was yelling out, switching between BlackGuilmon's enraged voice and Takato's, while ChaosGallantmon's body was moving around frantically and firing dark blasts from his shield and spear in random directions, as Aizen found it much more entertaining to see ChaosGallantmon destroy himself from the inside out, however, the traitor of the Soul Society was unaware of what was happening to Sakuyamon.

-Within an unknown location-

Rika let out a small groan as she could feel someone gently shaking her left shoulder, in which the Digimon Queen opened her eyes to see it was Renamon who woke her up.

"Renamon, what happened?" Rika questioned, as Renamon helped her up, before the redhead looked around to see she was no longer in the Champion Hunter's Death Zone Stadium, but an area filled with Japanese feudal style buildings, which were all coloured black, as the ground was coloured white, which caused Rika to ask. "And where are we?"

"We are in my mind." Renamon replied, as the vixen Digimon watched as a white sun set and the sky changed from black to white, as a black moon appeared in the sky, while the buildings and ground switched colours too.

"Alright. But what's going on with the scene changing colour?" Rika then asked, in which Renamon held up her right arm, showing the yin-yang symbol on it and told her Tamer. "Balance. With every action, there is a reaction."

"And with everything, there is always an opposite." A female voice then stated, in which Rika and Renamon were a little surprised when two figures stepped out of the shadows.

The first figure looked exactly like Renamon, only her fur was coloured red, the areas of fur that were normally white were black and her eyes were a familiar yellow colour.

While the second figure was a young female around the same age as Rika, who was dressed in similar clothing to Rika's, except her T-Shirt was fuchsia pink, which had a large white coloured heart in the centre, as her hair flowed freely down her back, which caused Rika to ask the girl. "Who are you?"

Upon hearing the question, the girl let out a small giggle, before she said happily. "That should be obvious. I'm you, silly."

"But how can you be me?" Rika asked in confusion.

"It's just like BlackRenamon said. 'And with everything, there is always an opposite', meaning the second you entered Renamon's mind I was created to be your opposite." Rika happy doppelganger replied, before she told the real Rika, as she grinned at her. "Which means while you're normally serious and distant, I'm almost one hundred percent of the time cheerful and happy."

"BlackRenamon?" Renamon questioned, in which BlackRenamon replied. "That's right, though my appearance wasn't like this until last night when you and Rika mated with Takato and Guilmon. Thanks to their love, I was given the power of his Crimson Mode, which changed my physical appearance."

"Hold on. Does that mean Sakuyamon can change her Mode too?" Rika asked.

"You bet. And you'd better hurry. That meanie Aizen has corrupted Guilmon's mind and it won't be long until he and Takato are both gone." Rika's friendly copy stated in a more Rika-like serious tone, before she and BlackRenamon were each encircled by a light red aura that soon enveloped Rika and Renamon, in which they could feel a power that they had never felt before enter their very souls.

-Back Within ChaosGallantmon's mind-

"Pyro Grenade!" BlackGuilmon roared out, as he fired a dark purple sphere, which struck Takato in the chest and caused the leader of the Tamers to cry out in pain as he fell onto his back.

And his pain was further heightened when BlackGuilmon jumped onto Takato's chest, as his claws began to dig into Takato's skin, before BlackGuilmon's maw filled up with purple coloured flames, which the corrupted Digimon planned to use to destroy the one he now believed had killed the Digimon he loved, however, BlackGuilmon felt something was wrong when he couldn't perform his attack or even move.

-Outside of ChaosGallantmon's mind-

ChaosGallantmon could feel that someone was restraining him from behind, before he looked behind him and was surprised and confused to see Sakuyamon was the one holding him in a restrictive position.

However, before ChaosGallantmon could say a single word, Sakuyamon used her left hand and removed the bottom part of his helmet, before the enchanting Digimon deeply kissed ChaosGallantmon, which caused his eyes to not only widen, but to return from the wicked crimson back to their kindhearted yellow, while his armour returned to its original colours.

But it was then Aizen had to shield his eyes as an intense light of pure red energy shone from the direction of Gallantmon and Sakuyamon, and when the light subsided everyone back at the Hypnos headquarters were amazed to see that not only had Gallantmon changed to his Crimson Mode, but Sakuyamon had changed too from her normal form to a form known as her Miko Mode, which actually greatly impressed Aizen, though the traitor of the Soul Society still believed he was unstoppable, but was soon to be proven wrong.

"Fox Card!" Sakuyamon exclaimed, as she threw a card from out of her left sleeve, which struck Aizen's chest, in which he felt no pain, but it was then the wielder of Kyōka Suigetsu fell to one knee, as the strikes ChaosGallantmon had inflicted upon him caused intense pain to surge through his body, in which Aizen questioned. "What's going on? What did you do to me?"

"Simple. I used the power of my Fox Card attack to seal away your power, making you vulnerable to attacks." Sakuyamon replied, before the spell-casting vixen turned to Gallantmon and told him. "And speaking of attacks, go for it Gallantmon."

"Right." Gallantmon replied, before he exclaimed. "Invincible Sword!"

It was then Gallantmon's Blutgang sword began to glow as it was filling with an unbelievable amount of energy, before Gallantmon used all the power he had within his sword and created a huge slash, which in turn, created a huge wave of energy that Aizen was unable to escape from, causing him to feel the full force of Gallantmon's power.

It was then after Gallantmon's attack subsided, Gallantmon and Sakuyamon could see Aizen lying on the ground, covered in wounds and other painful marks, before his body fell into a dark red void, which opened up beneath him, in which the Champion could see Aizen was useless to him and had no further use.

Meanwhile, within Gallantmon's mind, Guilmon had returned to his normal colours and said to Takato in sad and apologetic tone. 'Takato, I'm sorry I hurt you.'

'It's ok, boy. I'm just glad we're friends again.' Takato happily replied, which made Guilmon happy, before the red dragon with the big heart said. 'Me too.'

However, it was then the Mega level Mode changed Digimon were both enveloped by the same dark red energy Aizen had fallen into and were taken out of the arena.
