Sōkyoku Hill is the highest point in all of Seireitei. At its summit stands the Sōkyoku, a spear used to carry out the ultimate punishment upon those guilty of heinous crimes.
When a Shinigami is judged guilty by Central 46, they are bound to the execution platform, and the Sōkyoku—manifesting in its true form, Kikōō (Firebird King)—will pierce their body—
In appearance, Kikōō takes the form of a gigantic golden phoenix. Each of its attacks carries destructive power equivalent to one million Zanpakutō, enough to completely annihilate a soul!
However, due to the existence of Hell in Bleach, Seireitei rarely resorts to such a cruel punishment.
After all, Shinigami pride themselves on maintaining balance, not destruction.
As a result, Sōkyoku Hill is a place most Shinigami avoid, treating it with fear and reverence. Under normal circumstances, no one willingly approaches it.
Yet in the eyes of certain "reckless" Shinigami, the desolate and uninhabited Sōkyoku Hill happens to be the perfect secret training ground—
For example, Urahara Kisuke, and Shihōin Yoruichi. Beneath Sōkyoku Hill, they carved out a vast underground training area, where they each achieved Bankai.
...
Whoosh!
With a faint tearing sound, space inside the underground training ground beneath Sōkyoku Hill suddenly split open into a cross-shaped black hole.
Fūjin Taichi stepped out, dragging the Tenshintai behind him.
Thud.
He planted the Tenshintai into the ground and plopped down onto a smooth rock, surveying his surroundings.
The enormous underground chamber stretched endlessly into the distance, as if the entire hill had been hollowed out.
A desolate, primordial atmosphere spread throughout the yellowed cavern, creating an intense pressure that made his chest feel tight—as if he could barely breathe, or might even burst into tears.
"I really need to hurry up, learn Bankai, and get the hell out of this place…"
Taichi sighed, then looked at the Tenshintai and thought to himself:
"In Bleach, Urahara took three days to master Bankai, and Kurosaki Ichigo only two and a half days.
Even if my talent isn't as absurd as theirs, I'm still a transmigrator—so theoretically…"
"…three to five days should be enough, right?"
With that thought, Taichi raised Zanpakutō: Kyūjūkyū and plunged it into the Tenshintai.
To his surprise, nothing happened.
"Huh? Is the Tenshintai broken?"
Scratching his head, Taichi pulled Kyūjūkyū out and instead inserted Zanpakutō: Ichi into the device.
In an instant, a flash of white light erupted—
Both Zanpakutōs, along with the Tenshintai, vanished!
"What the hell?! Where are my swords?!"
Taichi looked around frantically, only to see that a black-haired kid—around eleven or twelve years old—had appeared in the empty training ground.
The boy looked uncannily like Yasuo from League of Legends.
His features were delicate, almost doll-like, with thin arms and legs that made him look frail.
Yet he wore an extremely oversized blue-gray short robe, dragging along the ground like a long dress.
Cradled in his arms was a sharp Zanpakutō—
It was Kyūjūkyū, the sword that had just disappeared.
The flowing-cloud-style hilt rested diagonally against his shoulder, making him look exactly like a wind-wielding swordsman—Yasuo himself.
"You… are you Yasuo? Or my Zanpakutō—Kyūjūkyū?"
Taichi asked in shock.
No matter how hard he tried, he could never have imagined that his manifested Zanpakutō spirit would turn out to be a barely-grown kid.
So weak-looking that it seemed like Taichi could slap him once and make him call him dad.
"My honor has been long gone. My name is Fūjin Yasuo!"
The black-haired boy stared intently at Taichi with pitch-black eyes and spoke in a clear, youthful voice:
"Taichi… you can finally see me."
"So it really is you, the Happy Wind Man?!"
Taichi laughed in disbelief, half-annoyed and half-amused.
"Does that mean as long as I E fast enough, misfortune can never catch up to me?!"
With that, he casually flicked the boy on the forehead.
Smack!
Fūjin Taichi bent two fingers and flicked them hard against the black-haired kid's forehead, producing a crisp crack.
It looked exactly like the way adults used to tap watermelons to check if they were ripe—thump thump, nice and solid!
"..."
The black-haired kid clearly hadn't expected Taichi to treat him like that. After taking the forehead flick, he froze for a moment—then burst into loud, wailing sobs.
And as the kid's crying grew louder and louder, Fūjin Taichi's spiritual pressure surged higher and higher—
What the hell?!
Could it really be this… fun?
A single careless action had actually unlocked the true power of his Zanpakutō—Bankai.
His spiritual energy skyrocketed, and his mastery over his abilities became noticeably more refined!
Moreover, the very last obscure part of Bankai suddenly clicked at the instant the crying reached its peak—
So this is what Bankai is all about…
Yeah… it really is fun!
"Waaahhh… sniff…"
Although the black-haired kid was still crying, his sobs had clearly weakened, and Taichi's spiritual pressure stopped increasing as well.
"Alright, alright—stop crying already! I'll buy you candy later! I'll make sure you're happy enough!"
Even though Taichi had technically "defeated" his Zanpakutō spirit with just a single forehead flick, he couldn't bring himself to feel happy at all—
After all, he had imagined that his manifested Zanpakutō would be something like a bold, sexy big-sis type like Matsumoto Rangiku,
or maybe a super cool, mysterious, deadpan middle-aged man like Zangetsu!
But life was unpredictable…
Who would've thought that his Zanpakutō would manifest as a child version of Yasuo, crying from one forehead flick?
How was that supposed to be fun?!
Honestly, even Taichi didn't understand why he'd ended up connected to League of Legends' Yasuo.
Maybe it was because he chased "fun" too hard while gaming—and lost horribly every time?
So… perhaps Yasuo's accumulated resentment had infected his soul, causing both his Shikai and Bankai to carry the unmistakable traits of the "Happy Wind Man."
"As long as it's fun, who needs anything else?!"
Fūjin Taichi stood up and gazed at the cloudless sky, making up his mind:
Now that he had obtained Bankai, the next step was to deal with the Hollow inside him!
After all, he was about to take up a post in 1st Division, directly under the command of the Shinigami boss himself—
the iron-willed, zero-tolerance Yamamoto Genryūsai.
If he were to lose control and show signs of Hollowfication right under that man's nose…
that wouldn't just be a joke—that'd be suicide!!
So… he might as well strike while the iron was hot and completely subjugate the Hollow within—
That way, he wouldn't end up like White Ichigo, constantly popping out to fight for control of the body!
And besides…
If he got lucky, and the Hollow also turned out to be a little kid…
Then he'd really be happy all the way to the end!
"Alright! Reflect on the past, advance another step—
Then… Let's go!!"
