"These bones are pretty old… and there are quite a few rge Danger Beast remains here. It seems like a Super-Css Danger Beast was definitely active in this area. But we can’t be sure if it’s still hibernating or if it’s already moved to another habitat."

  Byn whispered his analysis.

  Given the sheer size of a Super-Css Danger Beast, even after venturing this deep into Seiga Cave, the passage ahead remained incredibly vast.

  "We’ll find out once we reach the very bottom."

  Kurome’s tone was resolute, despite knowing how dangerous this was.

  She had no choice—if she wanted to strengthen Yatsufusa, she needed to act fast. Otherwise, she would never be able to defeat her sister.

  As they ventured further down, the temperature steadily dropped.

  "It’s getting cold…"

  Kurome muttered, noticing the chill.

  Cold temperatures could affect the body’s physical capabilities—just as athletes perform worse in freezing weather, the frigid depths of this cave would also hinder movement and reaction time.

  However, Kurome had a way to counteract the effects—drugs.

  This time, she wasn’t reaching for the cookies infused with mild medicinal compounds meant for sustaining bodily functions. Instead, she took out a white pill—one that could forcibly enhance her abilities in a short period of time.

  But, of course, the stronger the effect, the worse the side effects.

  Just as Kurome was about to take the pill, Byn suddenly took off his coat and draped it over her shoulders.

  The unexpected gesture caught Kurome off guard. She froze, the pill still in her hand, just inches from her lips.

  "These drugs must have serious side effects. If possible, I hope you won’t rely on them too much."

  Byn expined.

  He pnned to investigate this matter further once they returned to the base.

  What exactly had the Empire done to these children in the Assassination Unit…?

  "..."

  Kurome’s lips parted slightly as if she wanted to say something, but she hesitated.

  Silently, she put the pill away, then pulled Byn’s coat around her and whispered, "…Thanks."

  This feeling… wasn’t so bad.

  For now, it was just the cold, and there was no real urgency to take the pill. She had simply gotten too used to relying on them.

  But if they encountered a crisis she couldn’t handle, she wouldn’t hesitate to take it.

  ...

  The deepest part of Seiga Cave was far deeper than Byn had expected. They had no idea how long they had been descending before finally reaching the bottom.

  They hadn’t encountered a single Danger Beast along the way, which only confirmed that something terrifying lurked at the deepest level.

  Thanks to his Mangekyō Sharingan, Byn was the first to see what y ahead.

  Sure enough, there it was—a Super-Css Danger Beast.

  Although Byn had never encountered one before, the sheer size of this creature made it obvious. It dwarfed any Special-Css Danger Beast he had seen, standing at least 100 meters tall.

  This had to be the "Death Tagool" Kurome had mentioned.

  Fortunately, it appeared to be in hibernation, lying motionless on the cave floor.

  Its appearance was bizarre—like a massive dinosaur, but with no flesh, only a skeletal frame of gleaming white bones. Its eye sockets were empty bck voids.

  If not for its steady, rhythmic breathing, one might have mistaken it for a lifeless skeleton.

  "I see it. It’s still hibernating. Let’s be careful going down—we can’t risk waking it."

  Byn whispered to Kurome.

  "Mm…"

  Kurome nodded slightly.

  Her heart pounded in excitement—she had taken a gamble, and she had won. Her luck couldn’t have been better.

  A Super-Css Danger Beast… If she could add it to Yatsufusa, her strength would skyrocket.

  Byn and Kurome carefully descended to the cave floor, drawing closer to the massive creature.

  "This is definitely Death Tagool. I’m making my move."

  Kurome murmured, keeping her voice low as she slowly unsheathed Yatsufusa.

  Byn stayed alert, ready to react in case anything went wrong.

  Kurome knew she couldn’t kill a Super-Rank Danger Beast in one strike, so she immediately summoned the corpses stored in Yatsufusa.

  Her pn was to severely wound Death Tagool first—only then could she finish it off with the final blow.

  Before the battle began, Kurome instinctively reached for her pills again.

  She needed them to fight at full strength.

  Byn immediately stopped her.

  "If you don’t take those pills, I’ll help you."

  "...!"

  Kurome’s eyes widened slightly in shock.

  Even now, he was still trying to stop her from taking them?

  "Also… lend me Yatsufusa for a bit."

  Byn held out his hand.

  He wasn’t offering his help for free—there had to be some benefits for him too.

  If he used Yatsufusa to kill a Super-Css Danger Beast, he would receive a massive System Points reward, while Kurome would still gain the enhanced power of Yatsufusa.

  It was a win-win situation.

  "This…"

  Kurome hesitated.

  Normally, a Teigu user would never let someone else wield their Teigu.

  But Byn was her commander—someone she was supposed to obey without question.

  Then, she suddenly realized something.

  "Wait! You’re already a Teigu user. You can’t wield a second Teigu at the same time!"

  "That doesn’t apply to me."

  Byn responded calmly.

  His "Double Kamui" wasn’t a Teigu to begin with, so the supposed "iron rule" of Teigu didn’t affect him.

  Without waiting for further argument, he reached out and grasped Yatsufusa’s hilt, taking the bde from Kurome’s hands.

  The moment he touched it, he felt an immediate and indescribable discomfort—likely a rejection reaction from the Teigu.

  If someone wasn’t compatible with a Teigu, they wouldn’t be able to use its full power. In many cases, the power would be significantly weakened.

  Some Teigu, like Esdeath’s blood-based "Demon’s Extract," even drove incompatible users insane.

  Of course, that Teigu was an exception. Most weren’t that extreme.

  Regardless, it was clear that Byn couldn’t fully harness Yatsufusa’s abilities.

  After all, he and Kurome had completely different personalities—there was no way he could wield it as seamlessly as she could.

  But that didn’t matter.

  To him, Yatsufusa was just a tool.

  A tool that would now carry the power of Kamui.

  In the next instant, Byn channeled Kamui’s energy into the bde—enchanting it as if imbuing a weapon with magic.

  With this, Yatsufusa gained the power of Kamui—an absolute attack that ignored all physical defenses!
