SailorStar9: After getting Chapter 3 out, this is Chapter 4 of this fic. For everyone who put this fic on your favorited and followed lists and/or story alerts, thank you, but remember everyone, a lot of authors (myself included) sustain on readers' reviews.

Disclaimers: I own nothing, except for the plot bunny. Heck, even the pairings aren't mine.

Chapter 4: Hirako and Aizen...the Reunion of Fate!

"There are a lot of familiar faces here." Ichimaru noted.

"Looks like we made it for the main event." Hirako grinned. "Aizen."

"Who are they?" Hitsugaya gawked.

"They're..." Suì-Fēng breathed.

"Hirako Shinji." Yamamoto announced. "I figured you were hiding the Real World."

"It's been a while since we last saw them." Hirako remarked. "Is there anyone in the Gotei 13 you guys want to say hello to?"

"No!" Hiyori snapped.

"Shut up, Hiyori!" Hirako barked. "I wasn't talking to you."

"What do you mean you weren't talking to me?" Hiyori fired back. "You're talking to everyone, right?"

"I'm fine." Love answered.

"Me too," Rose added.

"There's no one in the Gotei 13 I want to talk to." Hachi replied.

"Me neither." Kensei looked away.

"Ichigo isn't here." Mashiro looked around. "Why is that?"

"Where are you going, Lisa" Hiyori barked, when Lisa vanished via a Shunpo.

"In that case, I'll go say 'hi' to the Captain-Commander." Hirako headed off.

"How long are you going to play dead?" Lisa glared at her former Captain and stomped a foot at the back of Kyoraku's head.

"Oh my..." Kyoraku chuckled. "What a surprise. Look how beautiful you've become since the last time I saw you."

"Lie down right there." Lisa unceremoniously kicked him on the chin. "I'll show you just how strong I've become."

"Lisa," Kyoraku started. "I'm glad you are doing well."

"Idiot." Lisa muttered and returned to the Vizards.

"Did you come to settle your grudge?" Yamamoto asked, when Hirako appeared beside him.

"Against Aizen, that is." Hirako answered. "I don't have anything against you. One thing I am upset about is that fact you placed an incredibly strong barrier around this place to fight. If I hadn't found this guy keeping watch outside, we would have been circling this area forever." he pointed to the arriving Sasakibe.

"I'm very sorry." Sasakibe apologized. "I wasn't too sure whether to let them in, but considering the situation in here..."

"It's fine." Yamamoto assured. "Hirako Shinji," he turned to the former 5th Squad Captain. "Can we consider you an ally for now?"

"Isn't it obvious?" Hirako sighed. "You can't."

In response, Yamamoto slid his Zanpakutō slightly out with a thumb.

"Enough, both of you!" Guardian Frost cut in.

"We're not your allies." Hirako corrected. "We're Aizen's enemies and Tula-hime's personal ANBU. By your leave, my Lady." he bowed to Guardian Frost.

"Go get them, Captain Hirako." Guardian Frost grinned.

"You're finally back." Rose looked at their de facto leader.

"Are you done talking?" Love asked.

"Nope, but we can't waste anymore time." Hirako reminded. "The enemy is losing his patience."

"What a noisy kid." Ichimaru sighed, hearing Wonderweiss' howls. "He's ruining the mood. I hate it when he does that."

"There is meaning to Wonderweiss' words." Tōsen explained. "Sit back and watch."

"What is he trying to do?" Hitsugaya wondered as Hooleer vomited out a wave comprising of Gillians.

"Are those all Gillians?" Suì-Fēng was shocked.

"Let's go." Hirako gave the order and the Vizards donned on their Hollow masks.

Hiyori struck first, slicing a Gillian straight down with her Zanpakutō. Opening her mouth, she demolished the Gillians around her with a Cero beam.

Kensei's rapid punches literally smashed through the Gillian in front of him. A single stab from his short Zanpakutō took out the Gillian behind him.

"Mashiro Kick!" Mashiro's flying kick crumbled a Gillian's mask. "Kick!" her next two kicks took out another two more Gillians. She back-flipped and smashed her foot onto the mask of the fourth Gillian around her.

"You're all much too noisy." Hachi encased the heads of the Gillians in front of him with Kido boxes. "This isn't a party, you know. Please keep quiet." he clapped his hands together, removing the Gillians' heads off.

"You're in the way." Lisa came up from below, slicing through a falling and sealed Gillian head. "Don't roll these big things my way." using the falling Gillian heads as foot-stones, she sliced through the last Gillian before it could even fire its Cero.

"That's right..." Rose entangled the Gillian before him with his piano strings. "Come here. Come near me and become enslaved by my melody." the piano strings tightened around the Gillian, twisting it into oblivion.

Love, on the other hand, took a more direct approach by ripping a Gillian into two.

"Amazing!" Ōmaeda gawked. "They're incredible. They're incredibly strong."

"Who are these guys?" even Hitsugaya was shell-shocked.

"All eight of them," Guardian Frost started. "Are Captain and Lieutenant level Shinigami who had been forcibly Hollowified by Aizen over 100 years ago. And because Aizen reported back to Central 46 first, Urahara Kisuke was labeled a traitor and all eight of Aizen's test subjects were marked for execution. Hachi," she summoned the former Lieutenant of the Kido Corps.

"Tula-sama." Hachi voiced.

"Can you take care of Ukitake's injuries?" Guardian Frost requested.

"Understood, milady." Hachi nodded.

"What do you think?" Hirako moved in front of his former Lieutenant. "We've gotten pretty good at using our Hollowification, haven't we? Aizen, let's end this." he melted his mask off. Unsheathing his Zanpakutō, he struck down at Aizen's shoulder, only to be forced back by Tōsen's Zanpakutō, the former 5th Squad Captain moving back to avoid getting hit.

"I missed?" Tōsen wondered.

"Don't be ridiculous." Hirako snorted, lifting his head to reveal a bloodied eyebrow. "You hit me."

"I wanted to slice off everything above your left eye." Tōsen corrected. "I don't consider that a hit."

"Big talk coming from a small fry." Hirako rebuked.

"You must really hate the fact that you're going to be killed by a small fry." Tōsen retorted and charged straight at Hirako, only to have Komamura block the blade with his arm-guard. "Komamura..."

"Allow me to assist you, Head of Tula-sama's personal ANBU." Komamura requested. "You fought against those Menos Grande. That alone is enough for me to call you an ally. I have decided to fight with you."

"Komamura..." Suì-Fēng blinked.

"Listening him go off like that, but he has a point." Hitsugaya admitted as Halibel broke free of the ice block and proceeded to strike down at his back, only to have Lisa come down from above, the force sending Halibel over. Hiyori moved in, swatting the 3rd Espada off. "Guess, there's no time to question whether you're friend or foe."

"We don't really want to help out you Shinigami." Hiyori snorted. "But now, not the time to be saying that."

"That's right." Hachi agreed, walking towards Suì-Fēng and Ōmaeda, after healing Ukitake's more grievous injuries. "Strangers don't need a good reason to team up in battle."

"The enemy of your enemy is your friend." Lisa's Zanpakutō was already pulled out. "That's a good enough reason to join forces."

"Indeed." Hitsugaya smirked.

Kensei's Reiatsu-infused punch took out the last of the Menos.

"I wanted the last one." Mashiro whined. "You stupid idiot!"

"Shut up." Kensei removed his mask. "You can have that large one over there. Don't complain."

"The big one... over there?" Mashiro turned to Hooleer.

"Uniting against a common enemy is said to be one of humanity's bad habits, but that's not true." Rose remarked, his mask melting off. "It's not a bad habit, it's a survival instinct. In fact, it's at those times when spiritual unions are their most... what was that for, Love?" he snapped, Love smacking him on the back of the head.

"We're done talking about that." the former 7th Squad Captain chided. "Stop talking nonsense and focus on the things at hand." he pointed to Stark. "Take a look. He looks strong."

"Are you sure you want to remove your masks?" the 1st Espada asked.

"We can only keep them on for three minutes." Love explained.

"Mashiro Super Kick!" Mashiro's upward kick literally tore Hooleer into shards.

Tōsen blocked off Hisagi's tossed scythe.

"I'm sorry, Captain Komamura." the 9th Squad Lieutenant apologized. "Please let me join this battle."

Omake: Shinigami Illustrated Picture Book

Or aka, the Real Reason Why Hirako Hates Aizen So Much

100 years ago...

Hirako: (Exclaims in horror when he sees himself in the mirror, his hair was completely shaved off) What the hell is this?

Hiyori: (Laughing hysterically) Baldy Shinji really became a baldy!

Aizen: (Outside the Captain's barracks) I'm sorry, Captain. I trimmed your hair while you were asleep. But it seems I overdid it.

Hiyori: (Still laughing in the background) Ow, my stomach. My stomach hurts from laughing too hard. You're all shiny now.

Present Shinji: Do you have any idea how hard it was to grow out my hair afterwards? (Death glares the smirking Aizen) Aizen! You'll pay for that!

SailorStar9: In the next chapter, Hisagi joins Komamura to battle Tōsen in hopes of bringing his former captain back to his senses. Meanwhile, the other Shinigami form uneasy alliances with the Vizards: Lisa, Hiyori and Hitsugaya take on Halibel; Love and Rose cover for Kyōraku and Ukitake and face Stark; and Hachi, after tending to Ukitake's injuries, team up with Suì-Fēng and Ōmaeda against Baraggan. Hachi creates a barrier around Baraggan, yet he easily dissipate it. Hachi makes an armored wall between the three of them and Baraggan to buy some time. Hachi asks Suì-Fēng to use her Bankai again in exchange for a deal. Baraggan survived the first time she used it because he made the missile age and redirected the explosion away from him. When Hachi boxes Baraggan in with three more armored walls around him, Suì-Fēng fire her Bankai to defeat Baraggan once more, granted that Hachi will seal Urahara in a barrier for one month. Hirako, though failing to sneak up on Ichimaru, remarks that one more of Aizen's allies have fallen.

Now that's done, read and review.
