F cursed tools at the age of six, just thinking about it sounded impossible.

  Ding-dang, ding-dang…

  Satoshi let out a light breath and brought the hammer down with a steady strike. The immense physical strength granted by his Heavenly Restriade f effortless, even at his young age.

  "Your strength is good! But your rhythm is off," Takuya observed from the side. Though his tone was critical, he was secretly impressed.

  "Satoshi, you o pick up the pace here!"

  "Satoshi, trol your strength better!"

  "Satoshi, don't rush f, patience is key!"

  Takuya tinued correg Satoshi's teique, yet the more he watched, the more surprised he became.

  "What's going on? How is he improving so fast?"

  pletely focused, Satoshi absorbed every bit of Takuya's advice, making adjustments as he worked. Without even realizing it, his proficy had reached the threshold required to activate his Zanpakutō F Fun.

  [Prerequisites met. Zanpakutō (Cursed Tool) F Fun Activated.]

  Engrossed in his work, Satoshi didn't eveer the system's notification. He was fully immersed in the rhythmic strikes, his teique refining with every hammerfall.

  "Kids these days are terrifying. You 't uimate them at all."

  Takuya watched with growing astonishment. If Satoshi kept this up, he might truly be able te his first cursed tool at just six years old.

  Suddenly, Takuya's expression hardened. His sharp gaze locked onto Satoshi's movements.

  He reized the hammering teique, it was identical to his own.

  "Wait… How is this possible?"

  Satoshi's small frame shouldn't be capable of handling that level of ford precision. The teique required a level of trol and endurance far beyond a six-year-old's physical limits.

  "If he keeps going like this, he'll overstrain himself!"

  Takuya moved to stop him but in that instant, he hesitated.

  Before him, Satoshi's f momentum surged, an unstoppable force that froze even him in pce.

  The sound of metal strikial echoed through the workshop.

  Ding—Dang—

  Ding-dang-ding-dang—

  Satoshi's hammering grew faster, each strike more precise tha. His clothes were drenched i, steam rising from his body as he worked.

  "What the hell is happening?"

  Takuya, watg in shock, instinctively summoned his cursed energy, eling a gray-blue glow into his hands to intervene.

  Yet to his utter disbelief, his energy dispersed as if striking cotton, uo disrupt Satoshi in the slightest. He couldn't even make him pause.

  Amid the relentless hammering, Satoshi subsciously reached for Yoru, the cursed tool Takuya had set aside, and pced it into the f embryo.

  "Satoshi… are you really trying te a cursed tool?"

  "What kind of f method is this? Is he attempting to fuse aing cursed tool and refe it into somethiirely new?"

  As a master of cursed tool f, Takuya quickly grasped Satoshi's i. Yet, seeing it in a still defied his expectations.

  Before the bzing fe, an eerie chill emanated from the on.

  "What's going on? Why is there such a powerful frost attribute?"

  Then, realization struck.

  "I see… Yoru's ability to coagute blood stems from aribute! That's the source of its power."

  Despite being a master fer himself, Takuya had udied Yoru ih. A, Satoshi had grasped its properties with just a siouch, then immediately ied it into his f process without hesitation.

  "This is insane… Did I pletely uimate his talent?"

  Takuya's mouth opened, but he dared not speak. He feared any disturbance might disrupt Satoshi's process.

  He was witnessing something unpreted, a f method that could revolutiohe entire world of cursed tools.

  Meanwhile, Satoshi remaiterly focused, his brow furrowed in tration as sweat streamed down his face.

  In that moment, he was no longer a six-year-old boy.

  He was Nimaiya ōetsu, the Swod of Soul Society.

  The icy essence of Yoru merged seamlessly with the f embryo, taking shape into somethiirely new.

  For aire hour, the rhythmig of hammering tinued. Finally, Satoshi took his st swing.

  And with that, his first Zanpakutō was born.

  [Ding! gratutions, Host, on successfully f Zanpakutō: Sode no Shirayuki. Zankensoki Fun Activated.]

  [Zan-Ken-So-Ki: "Zan" represents swordsmanship. "Ken" represents hand-to-hand bat. "So" represents instant movement. "Ki" represents the way of spells.]

  [With the activation of Zankensoki, Host must upgrade each skill in order. Only upon reag 100% profi the current skill the be unlocked.]

  [All system funs have now been enabled! Additional funs remain damaged, please repair them to unlock further abilities.]

  As the system notifications flooded his mind, Satoshi finally allowed himself to rex.

  Then, exhaustion hit.

  His six-year-old body, strengthened as it was by Heavenly Restri, had reached its absolute limit. The prolonged f session had drained him pletely.

  So that's the requirement… f a Zanpakutō was the key to unlog its fun.

  And… the system's damaged funs actually be repaired? I don't know how yet, but at least now I have hope.

  Most importantly, I did it, I successfully fed my first Zanpakutō!

  His thoughts drifted as he g the on in his hands.

  So… Sode no Shirayuki, huh?

  It wasn't the stro ice-type Zanpakutō like Hyorinmaru, but Sode no Shirayuki was still an exceptional bde.

  I really want to see it with my own eyes...

  But fatigue pulled him under before he could say another word.

  His vision blurred as he turoward Takuya, then he colpsed, fast asleep.
