"How is it, Miss Tamayo?"
"There are no problems. This medicine should work on Muzan Kibutsuji too."
"In that case, let's mix all this medicine into the bullets."
"I've already mixed quite a bit. Just load the ammunition, and it's ready to use."
As Tamayo spoke, she looked at the dozen or so strange weapons set beside her. "We've also made over a dozen copies of that Light Bowgun from before. They aren't as powerful as the original, but they still work fairly well."
"Excellent. They can deliver poison from a distance, and now we have enough of them. This weapon really is a godsend for us."
Shinobu Kocho nodded in satisfaction as well. Suddenly remembering something, she asked Tamayo, "Speaking of which, Miss Tamayo, you've had dealings with Mr. Ye Chen before, haven't you?"
"Indeed. I worked with him before he joined the Demon Slayer Corps." Tamayo surveyed the fruits of their labor and answered with a smile.
"Do you think he's really been killed?"
"It's hard to say. He supplied me with blood taken directly from Muzan Kibutsuji himself for my research, along with a wealth of information, and he could produce all sorts of strange items." Tamayo thought for a moment, then added softly:
"Personally, I don't believe someone so unusual and powerful would die that easily."
"I see." Shinobu Kocho lowered her eyes. "Let's hope he's safe."

An utterly ridiculous scene was unfolding inside the Infinity Castle.

Behind them, a man with his Long Sword raised pursued them relentlessly. Every swing claimed another demon's life.
"What's wrong with this human!?
