Seeing as oro gets his spot in the lime light when he dies made me look at Kabuto's death. And by doing that I noticed, there's nothing really there. You kill him and you're thanked, the end. So I thought I'd add a little something to it. Tell me what you think and if it would make a good addition.
With a swift blow, Kabuto falls to his knees. Looking upon you, he laughs weakly, "Seems I miscalculated." the broken man tries to stand, but fails as you grab your weapon, "Bah!" he yelled, "You're still no match for Lord Orochimaru. He's slain many Shinobi like you!" Kabuto gasps for air as he falls to the ground. With his last labored breath he curses your name.
Nobunaga hears Kabuto's curse, and runs to the mouth of the cave. Seeing the fallen Nin, he runs to your side, eager to shake you hand, "Thank you, so very much! Now we may live in peace..."
Near the corner of the cave, you see a young Academy Student walking inside the cave. Thinking nothing bad can come of it, you let the youngster on their way. Next to the cave you etch another marking, bringing your Kabuto kills to [kills #].
This seems a lot better. It fixes the errors in the current Kabuto death. Also down the road if want, coding for your current weapon and title code be put in. Such as with a swift blow from your kunai. And, "He's slain many Anbu like you!"
Let me know what you think.
