Now, for anyone wondering what I mean by Sō Kyōkai no Yūzūi. It means Primal Sin Of The Two Worlds. Originally it was supposed to be 'Twin' Planes or Worlds but I... Yeah it completely slipped my mind.
Not even sure why I chose Yūzūi as his name either as depending on the Kanji used, it has a wide range of interpretations.
---
"Swallow All Things In Creation!"
"Bankai! Sō Kaikyō no Yūzūi!"
Black flames erupted around him, converging into his swords and clothing. His hakama burned with dark fire, revealing the well-sculpted body beneath—defined muscles honed through countless battles. His pants were baggy, designed for freedom of movement, but it was his transformation that truly commanded attention.
His hair had turned a striking silver.
A crimson marking ran from beneath his lower eyelids, trailing down his cheeks and merging into a jagged line at the center of his chest. Unlike a true Hollow, the markings did form a hole on his thorax—but not through it.
Raising his hand, he gathered energy in his palm—pitch-black with streaks of blood-crimson. He dragged his fingers down his face once more, and an oppressive aura exploded from his body, shaking the battlefield.
"What is that mass of power?!" Zakraem Bael snarled, his expression twisted in distaste. So, the battlefield now had monsters among its ranks. He wasn't complaining—this only made things more entertaining.
"What the hell is going on over there?!" Natsumi hissed, pulling her sword from the throat of a dying soldier. The metallic scent of blood clung to her, sweat and war permeating the air. Her clothes were soaked in crimson—a nauseating sight to most, but she had long grown used to it.
Still, her heart clenched with worry.
"This brings back memories… terrible memories." Serafall murmured, shaking her head. Her normally playful demeanor faded as she frowned, her eyes flickering with unspoken emotion. Then, in the distance, she felt a familiar energy signature.
"It can't be…"
Meanwhile, Hisashi stood his ground, adjusting to his new form despite having used it before.
"I promised myself… if I ever met you again, I'd make you suffer more than you made Serafall suffer."
Katerea Leviathan smirked. "Oh? That day? The good old times."
'And I remember her pain…'
[Flashback]
Days had passed since my victory over Yūzūi. When I woke up, I learned that Serafall had left for the frontlines, and all I could do was worry.
If only I had completed my Bankai training sooner, I would've been there with her. But she delayed my participation for another two years.
I spent those days training, donning my Hollow mask only for the eyes to manifest. That alone was enough to awaken deep-seated trauma in my mother.
What had I done when I was fully Hollowfied?
She wouldn't tell me, but that night, I had to hold her while she slept. It was that bad.
Now, I sat in a lotus position, preparing for the next step in my evolution. I realized that every time my power had manifested before, it had been a fluke. My Reiryoku had been changing in nature, which, in turn, affected my Ki, causing it to Hollowfy. A phenomenon I still didn't fully understand.
The problem? Hollowfying was excruciating.
Now that I had fused my Ki and Reiryoku, I could finally solve that issue.
"Here goes."
Dark red energy pooled in my palm. I swiped it down my face, successfully donning my Hollow mask. I heard voices in my head whispering—an endless chatter of instinct and hunger. I silenced them with sheer will.
The training was simple in theory but brutal in practice: I had to familiarize my instincts with my control.
I refused to give in to bloodlust.
At first, it was hell. Even with my willpower, suppressing those urges took everything I had. Days passed, and I forced myself to meditate, tackling my urges with philosophy.
Why do we hate?
Hatred is born from personal suffering, but suffering itself often stems from one thing—greed.
Wars are fought over wealth, power, resources. When people don't get what they want, they lash out. They kill.
At what cost?
The lives of thousands.
Funny, isn't it? I understood the root of all war… and yet, I harbored the same hatred. I was preparing to kill the damn bats without a second thought.
"Meh, no one will miss them anyway." I shrugged.
The voices quieted.
I tested my limits, keeping my mask on as I channeled energy to my fingertips. A ball of condensed power formed—unstable but controlled.
"Cero."
A violent explosion erupted in the distance, obliterating everything in its path.
At full power, that could wipe out entire mountains.
I smirked.
"I wonder what a Gran Rey Cero would be like?" A shiver ran down my spine. I was getting excited.
Turning back toward the Sitri castle, I found Natsumi watching me curiously.
"Hey, Mom. Training going well?" I asked with a grin.
"Of course. I'd be ashamed if my own son left me too far behind." She chuckled, but my smile faded slightly.
"Mom… are you sure about joining this war?"
"I promised myself five years ago that I'd stand by you through thick and thin." Her lips curled into a confident grin. "So, you won't get rid of me that easily."
I was touched.
"Thanks, Mom. For being supportive… and naïve."
She blinked.
"Wait. Did you just call me naïve?"
I deadpanned. "You're practically committing suicide."
Silence.
Then—
"Says the guy who would die if food ceased to exist," she shot back, unimpressed.
Vein bulge.
"YOU TAKE THAT BACK! FOOD IS LIFE!"
Natsumi sweatdropped.
"I'm starting to wonder if I'll ever have grandkids…"
"Forget grandkids! They'd just waste precious delicacies!"
"YOU TAKE THAT BACK! DO YOU THINK IT WAS EASY RAISING YOU?! I RAN OUT OF FOOD BECAUSE YOU COULDN'T KEEP YOUR BIG MOUTH SHUT!"
I clutched my chest in mock agony.
From behind, a soft voice sang, "Emotional daaaaamage~"
I turned to see Asami grinning, thoroughly entertained. I collapsed in anime-style despair. [A/N: Hello to the ladies reading my works. Though there aren't a lot of you compared to the gentlemen.]
"Asami… you traitor."
She only laughed.
Banter like this made life worth living.
But the mood turned somber as we arrived at the Sitri castle. The air was heavy.
"Hisashi-sama…" A maid approached hesitantly. "We received terrible news. Lady Serafall Sitri… she has suffered greatly in battle."
I froze.
"Take me to her."
She teleported us instantly. The moment I saw Serafall's frail form in the infirmary, my heart shattered.
I rushed to her side, gripping her remaining hand tightly.
"Serafall, stay with me."
"Hisashi…" Her blue eyes met mine. She was so weak. "You shouldn't be here."
"Who did this to you?" My voice was cold.
Serafall hesitated, but finally whispered, "Katerea Leviathan."
I clenched my jaw.
"Rest easy, Serafall-nee. I'm here for you. Always."
Tears slipped down my face, but I didn't care.
Serafall gently placed a hand on my head, her silent reassurance speaking volumes.
Katerea Leviathan…
Her days were numbered.
Present
Hisashi glared at Katerea, his aura spiking.
"Tearing her wings off… hearing her screams… it was fun." Katerea smirked, feigning melancholy.
Hisashi's expression darkened.
"Wrong move."

Happy Reading Everybody!
The Poll is still up till I finish this Volume, so plenty of time.
You can comment worlds you want me to right about and they will be added, but only the first 12.
And then once it's all over, I will intergrate 3-5 of the twelve worlds. This decision will be based on whether or not the top 5 world's are too complex or too dangerous, like planetary level beings freely roaming the planet.
The rest is up to you. Oh, and don't forget to vote for me. I am running low Powerstones for my grand project.
Also add this book to your collection if you like it. I may change the cover or the name, I don't know when but I will give you a heads up when that happens.
I would really appreciate it though
