Tasuki was originally one of a group of mountain bandits. When their leader died, Tasuki was to take his place. But before he was able to, one of his fellows bandits decided to snatch this role from him. Miaka, Nuriko, and Hotohori became involved because they had reason to believe that one of the as yet unfound Suzaku Sei was one of the bandits. Tasuki told them that their former leader had had a strange chracter on his body.
In the end, Tasuki was able to become leader of the group and defeat the would-be leader by using a special fan that he stole back from him. This fan, when it's user cried out the incantation "Lekka Shien!" would release flames of fire. But Tasuki decided to leave the bandits with a temporary leader and went after Miaka, Nuriko, and Hotohori, who had left them, still in search of the Suzaku Seishi. He admitted to them that he was the seishi they had been looking for, and joined with them, planning to one day return to his duty as leader of the bandits.
Tasuki uses his fan as his main attack, though he is also a very good martial artist, like Tamahome.
Though Tasuki, often claims that he "hates women," he thinks nothing of jumping to Miaka's defense and protecting her from harm. He has four sisters which caused this supposed despision toward women.
When in action, he is incredibly heroic (hey, I must admit I love 'im!)
