Uchiha Kyodai

Armour-Sleeved Single Hit

To Kyodai, defeating someone with a single blow was the best way to fight. It usually wasn't messy, didn't sap energy, and meant you could rid yourself of more enemies in less time. This was a sentiment shared by many Uchiha, especially Kyodai's cousin, Madara. Being new to the battlefield, Madara preferred ending other children's lives quickly, as to not prolong pain. 

When Kyodai had first started fighting other clans, she had also felt that by killing them quickly, it almost seemed like her opponents weren't really dead, something that had comforted her (unless it was a Senju). Now though, she viewed killing someone quickly as simply more efficient, and she knew that her opponents had people other than her to grieve over them.

Kyodai would never personally tell Madara, who happened to be the closest thing to a friend Kyodai ever had, but many other Uchiha saw killing  someone with one blow as a show of power and skill. Kyodai knew this to be true, as it became clear to her after participating in shows of power herself. 

Kyodai knew that Madara had to find out about the other Uchiha's competiveness in war by himself, or never at all. Madara dreamed of peace and was thoroughly empathetic.

This changed when Madara's two twin brothers died by Senju hand. In front of him. He was too shocked to be sad or angry. Kyodai noticed though, that Madara became even more protective of his last two siblings, and his empathetic nature soured a bit. It was painfully obvious to Kyodai that the death of his brothers only made him wish for peace even more.

The quote for this chapter is actually (according to Narutopedia) Madara's favorite quote. If it wasn't obvious, armour-sleeved single hit means to defeat someone with a single blow. I do not own the Naruto series.
