Hakuhei Sabi

The strongest swordsman in Japan. He is the owner of the deviant blade Hari. His catchphrase, as stated many times by Togame, is: "I will have you fall for me." Despite repeatedly being hailed as the strongest in Japan, his fight with Shichika is never seen, but merely discussed by Shichika and Togame afterward. He does lose the fight, and Shichika obtains Hari. He is the incomplete form of the Deviant Blade Zentou Sabi, created by Kiki Shikizaki at the same time as Kyotou Yasuri. Zentouryuu is a sword style which can use all things as swords, the opposite of Kyotouryuu, which uses no sword. Hakuhei's mother, Kokken Sabi, was the completed form of Zentou Sabi. However, she was killed by a nine-year-old Nanami. (Source: Japanese Wikipedia)
