Hang Kasturi studied 'silat' (Malay martial arts) under the same tutelage as Hang Tuah, Hang Jebat, Hang Lekir and Hang Lekiu. He became one of the 'hulubalangs' (knights) that served Melaka together with Hang Tuah. With the exception of Hang Jebat, Hang Kasturi and the others remained loyal to the Sultan to their dying day.
