After Amamiya Miyako arrived in the Human World, he didn't rush to the neighboring Karakura Town to find Ishida Ryūken.
Finding Ishida Ryūken was quite simple; he just needed to go through the hospitals in Karakura Town one by one, and he would eventually see Ishida Ryūken's name.
What Amamiya Miyako most needed to confirm right now was the cause of his own death, or rather, to find the list of people who died at the same time as Amamiya Miyako four years ago.
So, Amamiya Miyako came to the hospital in Naruki City to search for death records from five years ago.
At night, Amamiya Miyako reviewed the information he had gathered.
June 17, 200x, Deceased XXX, cause of death unknown, the deceased's expression before death was extremely distorted, as if they had experienced some immense harm...
Deceased XXX, cause of death unknown, condition before death...
Four years ago, there were many deceased with similar death symptoms, and the cause has not yet been determined.
Looking at the information in his hand, Amamiya Miyako couldn't help but clench his fists.
He could basically confirm that all these people died five years ago from Yhwach's Holy Selection.
'I still need to find time to visit the hospitals in Karakura Town and Naruki City.' Amamiya Miyako thought.
Naruki City is also located next to Karakura Town, and it is currently the headquarters of Xcution.
Fortunately, Ginjō Kūgo and his group haven't made any major moves against the Shinigami yet.
If it's just investigating hospitals, there shouldn't be any contact with them.
During his time in Naruki City, Amamiya Miyako wasn't overly busy.
Just as he had guessed, although it was located next to Karakura Town, the number of Hollows and loose souls was indeed not very large.
Therefore, Amamiya Miyako wasn't overwhelmed and had time to investigate some matters.
'Then, I'll work some overtime.' Amamiya Miyako thought, planning to spend the next few days finding as many loose souls as possible and sending them to Soul Society through Soul Burial.
Then he would temporarily leave Naruki City and go to Naruki City and Karakura Town for investigation.
As for the Hollows, he could only conduct a thorough, carpet-like search.
"Ah, that sounds quite troublesome," Amamiya Miyako sighed.
...
At Naruki City Hospital, Amamiya Miyako skillfully found the list of deceased from June 17, 200x.
Sure enough, it was identical to the death information found in Naruki City.
After finding the information he wanted, Amamiya Miyako immediately left.
As someone who had died in the Human World, Amamiya Miyako used his common sense and tools like maps to quickly find the hospital, get the information, and leave, precisely to avoid being discovered by the Shinigami stationed there.
'So, there's only one place left.' Amamiya Miyako looked into the distance, towards Karakura Town, where he had originally died.
Even now, Amamiya Miyako could still clearly recall the heart-pounding sensation of dying, and although the original owner had already passed away, that memory still left a deep impression on Amamiya Miyako.
A few days passed, and Amamiya Miyako had not yet entered Karakura Town to investigate, because the Shinigami stationed in Karakura Town was Vehicular Tani.
Amamiya Miyako often felt Vehicular Tani's spiritual pressure at the edge of Naruki City, as he battled other Hollows.
However, each time, it ended with Vehicular Tani's victory, so Amamiya Miyako didn't know how to reasonably enter without being questioned.
Just as Amamiya Miyako was at a loss, a powerful spiritual pressure fluctuation suddenly erupted in the distance.
There was Vehicular Tani's, and also the spiritual pressure of an unknown Hollow.
Moreover, as Amamiya Miyako perceived, the Hollow's spiritual pressure seemed stronger than Vehicular Tani's, and Vehicular Tani seemed to be subtly suppressed at that moment.
'The opportunity has come.' Amamiya Miyako dared not delay and immediately rushed to the battle site.
In Karakura Town, on an unknown mountain, Vehicular Tani was battling a strange Hollow.
Originally, he had only seen a black-haired, white-robed girl during his routine patrol.
Vehicular Tani thought she was a loose soul and wanted to approach her for Soul Burial.
But just as he was squatting in front of the little girl, a Hollow with bird-like feet and a beast-like shape suddenly appeared behind her.
Vehicular Tani then realized he had been tricked and was immediately attacked by the Hollow's tentacles.
Vehicular Tani quickly retreated, using his sword to block the continuously incoming tentacles.
Looking at the hole in his shoulder, Vehicular Tani began to grow anxious.
Such a strong Hollow was unheard of, and it even possessed the means to disguise itself.
"Oh, you dodged so quickly.
I thought I could kill you directly, Shinigami," the white-robed girl in front of the Hollow said regretfully.
"Shameless Hollow, transforming into a human," Vehicular Tani clutched his shoulder, intending to continue fighting it.
"Human?
Oh, you mean this form.
Indeed, transforming into this form and then feigning a little pity will make different people come up to talk," the white-robed girl's face began to change, her human skin gradually peeling away, revealing its true form: a grotesque skull mask, from which a long tentacle extended, connecting to the beast's head behind it.
"Thanks to it, I've tasted many delicious souls," the beast laughed at this moment.
"And you, Shinigami, an existence that hinders my feeding, should disappear sooner."
"So it's you," Vehicular Tani exclaimed, recognizing the true identity of this Hollow at that moment.
The Hollow's codename was Grand Fisher, and it was recorded in Soul Society.
Its characteristic was using a mimetic lure on its head to disguise itself as a human, specifically attacking unsuspecting individuals with high spiritual concentration.
Moreover, this Hollow was very cunning, always managing to escape from the Shinigami.
'This is bad.' Vehicular Tani's heart sank.
If he hadn't been injured, he could at least defeat this Hollow, if not outright subjugate it.
But the current situation was a bit grim.
When Amamiya Miyako arrived, Vehicular Tani was already struggling, and the situation seemed one-sided.
Amamiya Miyako dared not be careless; a Hollow that could overwhelm a Fourth Seat was no small fry.
"Ruler, mask of flesh and blood, all creation, soaring wings, those who bear the name of man, truth and temperance, standing on the dream-wall of unknowing with only claws and fangs." Amamiya Miyako chanted the incantation completely, pointing his hand at the Hollow.
"Hado #33, Sōkatsui."
The blazing explosion from his hand roared out, flying towards the Hollow.
"What?" The Hollow was startled, having been so engrossed in the battle of tormenting the Shinigami that it hadn't noticed a new spiritual pressure appearing nearby.
By the time it reacted, Sōkatsui was already rapidly approaching it.
"Ah ah ah ah!" Grand Fisher screamed.
Sōkatsui hit its torso, and a quarter of its body was struck, turning to ash.
"Damn Shinigami, ambushing me!" Grand Fisher quickly moved away from Vehicular Tani and roared at Amamiya Miyako.
'Damn it, I was about to kill this Shinigami, and another one appeared.
I'd better escape now.' Grand Fisher dared not continue fighting and turned to flee.
"Stop!" Amamiya Miyako used Shunpo to pursue, but Vehicular Tani suddenly coughed up a mouthful of blood.
Amamiya Miyako had no choice but to stop, running to Vehicular Tani's side and using simple Kaido to heal his body.
"You've been a great help, Rain Palace Fifth Seat," Vehicular Tani said with a wry smile.
"It's good that you're alright, Vehicular Tani.
It's a shame that Hollow still got away." Amamiya Miyako continued to use Kaido, but since he wasn't proficient in it, he was only providing rough treatment.
"That Hollow just now was named Grand Fisher; Soul Society also has records of it.
It's a very cunning Hollow.
Even I was deceived by it, which is why I suffered severe injuries.
Now that it's injured, it probably won't appear for a while," Vehicular Tani explained.
'So it was it.' Amamiya Miyako was surprised, not expecting it to be this infamous Hollow.
"However, with me so severely injured, the guarding of Karakura Town will be somewhat troublesome," Vehicular Tani said with a wry smile.
Amamiya Miyako heard this and had a flash of inspiration.
He hadn't expected such a rare opportunity to truly appear.
