Here is a complete rundown (in sequence) of the these Bleach filler Arcs.
The Bount Arc: Episodes 64-91
In this episode, Urahara’s hidden modified souls meet Ichigo, Chad, Renji, and Orihime. They might as well accept their fate and fight each other now. It is revealed later that Kisuke created Noba, Kurodo, and Ririn to single out specific organisms called Bounts. These beings are regular folks who have discovered a way to drink in pure souls and become immortal.
Soon after, evil Utagawa Ryo kidnaps Ishida Uryu, but good guy Yoshino switches sides and thwarts the kidnapper’s plans. The higher-ups in the Seiretei are understandably worried about the Bounts, and Team Ichigo has finally met the main villain, Jin Kariya. After killing Yoshino, he launches a massive assault against the Shinigami standing in his way, before retreating to his hideout, from which he can enter the Seireitei via a portal.
Thankfully, the balance of power between Ichigo Kurosaki and Kariya is kept in check by his use of Tensa Zangetsu. Uryu puts an end to the conflict by opening the portal for the Bounts to pass through in the Bount arc’s concluding episode, “Shinigami and Quincy, the Reviving Power”.
The Bount Assault On Soul Society Arc: Episodes 92-109
There is a strong possibility that Uryu’s strategy to fight the Bounts in Soul Society may fail. Since the bad guys can harvest Reishi from any part of nature, they have a distinct advantage. The Bounts have no way of getting around the checkpoints between the Rukongai and Seireitei neighborhoods. After recruiting a crew of formidable combatants and obtaining assistance from a Squad Eleven spy named Ichinose Maki, the Bounts successfully break in.
In Episode 98, “Clash! Kenpachi Zaraki vs. Ichinose Maki”, the Captain of Squad Eleven faces off against and ultimately vanquishes his former subordinate, who betrayed the team. Naturally, Kariya tells his new “allies” that they are no longer needed because their mission has been completed, further humiliating them.
Finally, Captain-Commander Yamamoto Genryusai takes charge, issuing orders for his subordinates to disperse across the Seireitei and detonate the Jokaisho “bombs” hidden beneath the surface.”The Wailing Bount! The Last Clash” depicts the final showdown between Ichigo Kurosaki and Jin Kariya, which concludes with the villain floating off into the distance.
The Zanpakuto Unknown Tales Arc: Episodes 230-265
Muramasa, a renegade Zanpakuto spirit, is the protagonist of the Zanpakuto Unknown Tales arc. This bad guy wants to break free from the Shinigami’s control. Thus, Muramasa severes the ties that bind nearly all Shinigami to their Zanpakuto.
At first glance, it appears that Muramasa has trapped the Captain-Commander inside an impenetrable shield. Yamamoto has been keeping up the barrier to prevent the theft of Ryujin Jakka. Muramasa ensnares the Captains and their Zanpakutos inside the raging fire and then proceeds to the final stage of his plan.
After decades in jail, his original owner, Kuchiki Kouga, is finally freed thanks to him. Kouga strikes back at Muramasa, babbling something about how his Zanpakuto betrayed him. Even if Ichigo Kurosaki gets there in time, the Zanpakuto ghost takes him and the other former Shinigami into his “inner world”.
