A samurai's daishō

The word daishō (meaning "big little") refers to the two swords carried by the samurai. Made up of the katana (longer sword) and the wakizashi (shorter sword), the daishō symbolized the owner's samurai status. Usually only the katana was used to fight - the wakizashi was mainly used historically to cut off the heads of enemies and in seppuku.

However, the Two Heavens technique utilizes both the katana and wakizashi, using both swords to be able attack and defend at the same time, and hence the technique is rumored to be invincible.
