White Invasion

The White Invasion is a major conflict where the Gotei 13 and the Vizard battle against Sōsuke Aizen and his Arrancar army to stop him from making the Ōken.

Prelude
Aizen finishes addressing the intruders of Las Noches. He then calls for the top three Espada (Coyote Starrk, Barragan Luisenbarn, Tia Harribel) and their Fraccion to accompany him to Karakura Town, and leaves the 4th Espada, Ulquiorra Cifer, in charge of the castle while he's away. With that, Aizen, along with Gin Ichimaru and Kaname Tōsen leaves via Garganta to the Human World, where the Shinigami are waiting for them. It is revealed that Karakura Town is currently in Soul Society and right now they are in a Fake Karakura Town, which causes Aizen to change his plans to simply defeating the Gotei 13 and making the Ōken in Soul Society.

Early Stages
As the Gotei 13 talk about their enemies, Genryūsai Shigekuni Yamamoto uses Jōkaku Enjō to trap Aizen, Gin, and Kaname, while at the same time allowing them to fight the Espada without any worries. Baraggan decides to take charge and figures out that there are four pillars keeping Karakura Town in Soul Society. He brings out some Hollows to destroy these pillars but they are easily killed by Izuru Kira, Yumichika Ayasegawa, Ikkaku Madarame, and Shūhei Hisagi, who are protecting the pillars. However, Baraggan isn't phased by this and decides that he'll counter against four "ants" with four "dragons" and sends four of his Fraccion to attack the pillars.

Yumichika is confronted by Charlotte Cuuhlhourne but Yumichika doesn't take him seriously due to his appearance. However, he is soon overpowered by his opponent and is forced to release his Zanpakutō, Fuji Kujaku. After Charlotte still overpowers him though, his opponent uses his strongest technique, Rosa Blanca, and the two are completely hidden from view. This ends up being Charlotte's downfall however, as this allows Yumichika to use the true form of his Zanpakutō, Ruri'iro Kujaku, which absorbs all of his opponents reiatsu. Kira is confronted by Avirama Redder and his opponent quickly enters his Resurrección, Águila, which gives him heavier wings. Kira uses this to his advantage though by releasing his Zanpakutō, Wabisuke, and making his wings even heavier and causing him to fall to the ground helpless. After Kira explains why his Zanpakutō best reflects the philosophy of the Third Division, he beheads Avirama and tells him not to forgive him. Hisagi is confronted by Findor Carias, who destroys a large majority of his mask and claims that because of this he's now as strong as a lieutenant. He proves this by quickly overpowering his opponent but Hisagi is able to turn things around by releasing his Zanpakutō, Kazeshini. Findor is unable to read the Zanpakutō's movements and is easily killed by his opponent. Ikkaku is confronted by Choe Neng Poww but ends up losing the battle, along with the pillar, because he doesn't want to reveal his Bankai in front of so many people. Sajin Komamura is forced to step in and he easily defeats Poww by activating his Bankai, Kokujō Tengen Myō'ō. Tetsuzaemon Iba confronts Ikkaku and reveals that he knows about his Bankai and scolds him for being so selfish and allowing a pillar to be destroyed. Sajin overhears this conversation but decides not to say anything.

After the pillars are successfully protected, Soifon and Marechiyo Ōmaeda decide to battle with Baraggan's last two Fraccion, Ggio Vega and Nirgge Parduoc. The rest of the Shinigami decide to fight as well, with Jūshirō Ukitake and Shunsui Kyōraku facing off against Starrk and Lilynette Gingerback, while Rangiku Matsumoto and Tōshirō Hitsugaya confront Harribel and her Fraccion. After Yamamoto tells everyone to defeat their enemies and to not let them take a single step into Soul Society, the Shinigami begin their battle. Hitsugaya starts fighting Harribel, while Rangiku fights with all three of Harribel's Fraccion, Sun-Sun, Mila-Rose, and Apache. She appears to gain a small advantage against them after releasing her Zanpakutō, Haineko, but the three of them are eventually able to overcome it. Soifon immediately overwhelms her oppenent, Ggio, and she goes to finish him off with Suzumebachi, but after beginning to fight seriously and going into his Resurrección, Tigre Estoque, he appears to gain the advantage. Marechiyo fights with Nirgge and is able to successfully hit him with Gegetsuburi but his opponent survives and nearly defeats Marechiyo until he is finished off unintentionally by Soifon when she is thrown away by one of Ggio's attacks. Soifon and Ggio continue battling and Soifon is nearly killed until Marechiyo steps in and protects her. After this, Soifon decides to get serious and is able to easily kill Ggio. Soifon and Marechiyo then decide to confront Baraggan.

Rangiku is easily overpowered by her opponents and she is nearly defeated until Momo Hinamori arrives to save her. Momo is able to gain an advantage against the three of them by using a combination of her released Zanpakutō, Tobiume, and Kidō. This ends up causing Shunsui and Starrk to begin fighting seriously as well, which in turn causes Lilynette and Ukitake to begin battling. Sun-Sun, Mila-Rose, and Apache survive the attack and they all go into their Resurrección, which allows them to unleash their "pet" Ayon against Momo and Rangiku. Ayon easily defeats both Rangiku and Momo, forcing Hisagi and Kira to come into the battle. Kira begins healing the two fallen Shinigami while Hisagi begins battling the monster, but Ayon easily overpowers him as well. He then stops a sneak attack by Iba and immediately goes over to Kira's location. Before he can get to him though, Yamamoto steps in and after releasing his Zanpakutō, Ryūjin Jakka, he incinerates Ayon, which causes Harribel's Fraccion to attack Yamamoto but they are incinerated as well. After this happens, the fights with the top three Espada truly begin and their rankings are revealed, with Harribel being #3, Baraggan being #2, and Starrk being #1.

Middle Stages
Kira begins healing Hisagi and Iba as well, while Komamura protects him and the two of them watch the ongoing fight. The Shinigami captains begin having trouble against their opponents and Harribel decides to finish her battle by going into her Resurrección, Tiburón. She immediately cuts off the right half of Hitsugaya's body and decides to go after Yamamoto next as revenge for him killing her Fraccion. However, Hitsugaya attacks her from behind and reveals that he had used an ice clone as a precaution. Soifon battles with Baraggan, but because of his ability to age any of her body parts, she is much slower. Baraggan then goes into his Resurrección, Arrogante, and uses his power to turn Soifon's left arm to nothing but bone, forcing Marechiyo to cut off the deteriorated arm. Marechiyo then stalls Baraggan while Soifon begins a plan. Hitsugaya and Harribel continue their fight, with neither gaining an advantage, until Hitsugaya uses Hyōten Hyakkasō, which causes Harribel to be encased in ice. As Marechiyo continues distracting Baraggan, Soifon activates her Bankai, Jakuhō Raikōben, and is able to successfully hit Baraggan with it.

Starrk decides to get serious in his battle with Shunsui and reveals that Lilynette is the other half of his power. He combines with her, and goes into his Resurrección Los Lobos. He is able to push Shunsui back with Cero Metralleta, but Ukitake enters the battle and is able to redirect the attacks back somehow. However, Starrk easily figures out that he was able to do this with his released Zanpakutō, Sōgyo no Kotowari. All of a sudden a Garganta opens up, with Wonderweiss Margera and Fūrā exiting out of it. Wonderweiss stabs through Ukitake's stomach with his arm, while Starrk fires a Cero point blank at Shunsui, leaving the two captains defeated. Wonderweiss then lets out a battle-cry that destroys the ice Harribel's encased in, freeing her, while the smoke from Soifon's Bankai goes away revealing Baraggan to be alive. Fūrā blows away Yamamoto's Jōkaku Enjō technique, freeing Aizen, Gin, and Kaname. As the Shinigami lose all hope, the Vizard arrive to battle Aizen.

Fūrā lets out a bunch of Gillian and the Vizard don their Hollow masks to battle them. As they easily take care of the Gillian, Shinji Hirako decides to go and attack Aizen but Kaname stops the attack and goes after Shinji. However, Komamura arrives and protects Shinji, while at the same time deciding to fight Kaname. The Vizard decide to join in on the fights, with Lisa Yadōmaru and Hiyori Sarugaki helping out Hitsugaya, Hachigen Ushōda helping out Soifon and Marechiyo, and Rōjūrō Otoribashi and Love Aikawa battling Starrk. Mashiro Kuna goes up to Fūrā and easily kills it with a bunch of repeated kicks while Wonderweiss watches. As Komamura and Kaname talk, Hisagi joins in on their battle.
