Even though most of the kingdoms in my fantasy world are based on medieval Europe, there is one kingdom that is based on feudal Japan. As a result, they have similar armor and weapons as samurai. Among these weapons are the katana long sword and the wakizashi short sword. When these two blades are used at the same time, they become what is known as the Daisho Sword Pair. The long katana is used for offense while the short wakizashi is used for defense. When these two swords are used simultaneously, they become a force to be reckoned with on the battlefield. In my spin-off fantasy trilogy, one of the main characters will come from this Japan-like kingdom and will carry a Daisho Sword Pair wherever they go. In the heat of battle, this character will become a demon with a blade.
