Saeki Himuro is the combat butler of the Ookouchi family. He is usually seen smelling a single rose or reading a book while his master throws rose petals behind him. Himuro loves money more than anything in the world, but he does not try to gain the Sanzen'in inheritance because he already has his master's money. Himuro robs Hayate of his necktie in their first meeting so Hayate gives him the nickname "necktie man" in the manga. In the anime, this nickname is changed to "Prince Necktie".
Like Klaus, he throws roses like daggers. He can also create a rose whip and can use a powerful move that involves striking the opponent with rose petals. He is very agile and is able to stand on the side of trees. Unfortunately, he has a glaring weakness against money. In fact, Klaus "defeats" him by offering him a large sum of money, and he strangely begins to bleed profusely as if struck immediately after. His ultimate attack has yet to be revealed. Despite being greedy, he does care for the well being of his master.
