Ikusa Ayasaki is a character in the anime and manga series, Hayate the Combat Butler. He is Hayate's older brother and describes himself as a lifesaver.

He is a kindhearted person willing to help anyone in need and this trait is looked heavily upon by Hayate who considers Ikusa to the only true family member he has. Ikusa is also much stronger, agile, and faster than even Hayate and like his little brother hates his parents due to their father being unwilling to get a job and their mother's compulsive gambling and their criminal actions.

He knocks out his father in the finale of the manga but does not kill him. He does however give his father a beating for all the horrible action he committed on others.
