Kyōsō Ken

Ken is one of the top kendo and sword masters of Wano while also being a skilled and powerful pirate.

Family
Kyōsō Budo- Budo is Ken's twin brother but most importantly he is his rival. He despises everything about his brother and Budo feels the same.

Kendo Mastery
Ken has mastered all the dans of Kendo and is one of the most skilled in all of Wano. His skill is almost unrivaled as well as his strength. Even with a kendo sword which lacks edges or anything to cut Ken is still just as deadly as if he was holding a real weapon

Burazāsupurittā
Burazāsupurittā or "Brother Splitter" is Ken's main weapon that he always has hanging from his side. When not in a kendo battle and when needing to be more deadly he will use this blade. It is a Metio grade weapon, but its true grade is unknown.

The Sibling War
Nearly 45 years ago Ken and his brother both attended tournaments on the same day, Ken went to a kendo tournament and Budo went to a Sumo match. When they returned they enjoyed it so much they began to have a little debate about which martial art was better. While it started as a friendly debate is soon spiraled into a ten day long argument over which was the supreme way of battle.

Eventually they turned in different directions and kept walking. Ken eventually found his way to a Kendo dojo and began working on his style and strength. If he couldn't tell Budo how superior Kendo was he would have to show him. From then on they have been fighting for years to prove one was superior over the other, the sword vs the sumo.

These fights escalated as they rose in power first starting as little scuffles just two children fighting not knowing what they were doing eventually became cataclysmic events that shook the very earth as their clashes were a danger to anyone around them. They have battled hundreds of times, but so far neither has defeated the other.
