Himuro Saeki (冴木 ヒムロ,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 Sanzenin inheritance because he already has his master's money. Himuro robs Hayate of his necktie in their first meeting so Hayate gave 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 is also capable of creating a rose whip and executing 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 "defeated" him by offering him a large sum of money and he strangely began 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 and even abandoned Hakuo's butler tournament arena (he was in the middle of a match with Hayate) just to save his master.
Himuro has dark brown hair and brown eyes. He wears a butler's uniform and holding a rose.
