-Fake Karakura Town Arc-
He is then seen with the rest of the Vizard arriving at the fake
Karakura Town, intercepting Aizen, Ichimaru, and Tōsen's release from
Yamamoto's fire prison.
When Shinji asks his fellow Vizard if they have anyone in the Gotei 13
whom they want to speak to, Hachigen states that there is no one in the Gotei 13 with which he wishes to speak to.
Once the huge Hollow creature spews forth a large horde of
Gillian-class Menos from its mouth, Hachigen is among the Vizard when
they put on their masks to prepare for battle.
Hachigen stands ready for battle as the other Vizard draw their
Zanpakutō and uniquely manifests his inside a rectangular barrier in
between his hands.
Hachigen shows his uniquely powerful Kidō skills in battle by simply
snapping his fingers which erects large rectangular barriers around the
heads of four Gillian. He then states that everyone is getting too
excited and they are not at a festival so they should all quiet down, he
then claps his hands together which causes the barriers to cut the four
Gillian's heads off of their bodies.
After dealing with the Gillians, Hachigen aids Suì-Fēng
and Marechiyo Ōmaeda
in their battle against the Espada Baraggan Louisenbairn
Hachigen addresses Suì-Fēng, telling her it's been a long time since
they last saw each other. Suì-Fēng acts as if she doesn't know him, to
which Hachigen comments that he figured she would say as much, and that
he is not surprised that she doesn't think well of the Vizard. Baraggan
interrupts, stating that it doesn't matter who they are or what powers
they have, for everything is equal before him. Baraggan then taunts
Hachigen telling him to come to him so he can turn him to bone and
destroy him. Hachigen claps his hands together and forms a barrier to
ensnare Baraggan. Hachigen states that he has seen what Baraggan can do,
being the whole reason he came to fight him. Hachigen tells him all
attacks are the same unless they can touch you, and that Baraggan wields
a truly fearsome power. Baraggan touches the barrier and it begins to
deteriorate, much to Hachigen's surprise. Baraggan then asks if he
thought that age could not touch Kidō.
Baraggan continues explaining how everything dies, including the
things that Humans and Shinigami make. Baraggan contends that 'forever'
is nothing more than a meaningless word born out of the fear of aging.
He then proceeds to attack.
Hachigen generates a rectangular plank in between his hands and
multiples it into rows in front of him. The constructs connect together
into a wall that holds off Baraggan's Respira. Baraggan states that he
already has said that it will rot, as the Respira begins to chisel away
at the integrity of the wall. Hachigen begins recite the incantation, to
which Baraggan comments on how clever Hachigen is, since an incantation
said after a spell can strengthen it. But he also warns that he is too
late. Hachigen puts his hands up in front of him saying the spell name,
causing large beams to build up in front of him, creating a very thick
and large wall many stories high to separate him and Baraggan further.
Hachigen then calls out to Suì-Fēng
, asking her for her help as he needs her Bankai. Suì-Fēng apprehensively comments on how the Vizard
even knows about her Bankai. Hachigen pleads with her that he knows she
doesn't want to work with them because of their connection to Urahara,
but he reminds her that this is not the time for grudges. Suì-Fēng
continues to be uninterested in teaming up with him, to which Hachigen
relents and tells her he will make a deal with her. Meanwhile Baraggan
is losing patience and proceeds to try to destroy the wall before he
notices something behind him.
Hachigen continues to create more barriers starting with "Koko No Jomon
", a pinwheel shape barrier on Baraggan's right; "Kigai No Jomon
", a prism shaped barrier made of a multitude of smaller prism shapes on his left and finally "Hoyoku No Jomon
a large post with what is similar to wings fanned out forward eclipsing
all other constructs. Hachigen calls out the spell name "Shiju No Saimon
", causing the spell to fully take effect as "Kigai No Jomon
becomes similar to an umbrella as a large box shaped barrier connects
all other constructs Hachigen has previously made and entraps Baraggan
completely. Baraggan laughs at Hachigen's attempts as ridiculous to
think he can be sealed in this, laughing at the idea of trying to buy
time against one who controls aging. Baraggan acquits it to being
similar to spitting on the face of god.
Hachigen simply states the barrier is not to seal him; he goes on to
explain that Baraggan used his aging on Suì-Fēng's Bankai and made it
explode far away from him so that he escaped the explosion. Hachigen
then deduces that if Baraggan is in a place where he can't escape the
explosion and the explosion is too close to him, then his powers won't
be fast enough to keep it away from him. The pinwheel section of barrier
partially opens as Suì-Fēng sticks Jakuhō Raikōben in and asks Hachigen
to promise her again that tomorrow, he will seal Kisuke Urahara
in one of his barriers for a month. Hachigen promises and Suì-Fēng
smiles as she fires her Bankai, causing the barrier to seriously rupture
After the attack, Suì-Fēng
is left greatly exhausted, causing her to fall out of the air which
prompts her lieutenant to go to her aid. Hachigen remarks at how
surprised he is that she cracked the "Gates of the Four Beasts
", going further to note how unbelievable her power is. He then snaps his fingers causing the Barrier to fix itself.
Hachigen then calls down to Ōmaeda to ascertain captain Suì-Fēng's
status. Ōmaeda yells that she is not alright and that his inclusion of
her in his plans could have killed her. Suì-Fēng stands up and remarks
that she can normally only use "Jakuho Raikoben
" no more than
once every three days and she has just done it twice in one day. She
smirks and comments to Hachigen that he'd better pay her back, to which
he agrees he will uphold his end of the bargain. Immediately after the
exchange, the building that Suì-Fēng and Ōmaeda are standing on begins
to crumble and fall apart right out from under them. They realize too
late that it's the deteriorating powers of Baraggan's Respira.
Baraggan screams from beyond the smoke screen that he will never
forgive them. Hachigen's eyes widen in surprise stating that it's
impossible for him to be alive. Baraggan continues telling them he will
not forgive them for injuring him. He finally appears with the left half
of his face and his right arm blown off. He tells them they will pay
for turning their backs on him. He brings forth more Respira to engulf
the area. Hachigen puts up a barrier and dons his Hollow Mask in order
to repel the Respira. Baraggan tells him he is clever but asks Hachigen
who he thinks he is playing Hollow with. He further says that he should
know his place for he is the the Great Emperor, the God of Hueco Mundo.
The Respira breaks through Hachigen's barrier, and Suì-Fēng screams his
name as Baraggan laughs. Baraggan goes into a speech about how all are
beneath him, as his Respira attacks Hachigen, shattering his Hollow
Mask. As he continues to speak Hachigen's right arm is enveloped in
Baraggan's Respira causing it to begin deteriorating. Hachigen covers
what is left of his arm with a barrier, causing Baraggan to pause and
question what Hachigen has done to his right arm. Hachigen then points
at Baraggan to which the Espada asks what he is doing. Hachigen plainly
states that he gave it to him.
Baraggan's chest glows to which he asks what is happening. Hachigen
explains that Baraggan stated that only his power is absolute. As the
barrier placed in Baraggan's stomach is revealed, it begins to dissipate
unsealing Hachigen's deteriorating right arm that was held inside it,
causing Baraggan to deteriorate at an extremely fast rate. Baraggan
realizes too late that Hachigen cut off his arm inside a barrier and
transferred it to his stomach. Hachigen continues stating that if
Baraggan's power is truly absolute, then even he can't stand against it.
Hachigen notes that it was only a guess, but he is glad he wasn't
wrong. Baraggan becomes irritated at this. Hachigen continues stating
that in Soul Society
, there are no gods other than the Shinigami
the gods of death. Thus, anyone that isn't a Shinigami can never
understand the seriousness of his words. He asks that Baraggan forgive
them for their lack of belief, sarcastically calling him the "God of
Hueco Mundo" as Baraggan disintegrates due to his own power.
Hachigen remarks that he thought it was strange, because everything
that Baraggan touches grows old and rots, yet his own bones did not. He
then states a theory about how Baraggan must have had some other power
that kept his power away from him. When Hachigen sent his own power
inside of him, that power was negated. Hachigen details that he was
right as in the end Baraggan was just another small life fearing death
and trying to keep age at bay.
Hachigen is seen looking on helplessly as Hiyori is dying, unable to
help her as it seems he needs both hands to activate his healing powers.
Hachigen then agrees to take Hiyori and do what he can when Shinji decides to go fight Aizen. 
While he is doing his best to help Hiyori, Unohana comes back from Hueco Mundo and goes over to assist Hachigen. 
After Aizen's defeat, Hachigen is briefly seen along with Love,
Shinji, Rōjrūō and Lisa while Unohana expresses concern for Hiyori, and
appears to have had his arm healed, albeit in a sling.
