A womanizer with a wild streak, Shamal hits on every attractive woman he encounters, though he rarely succeeds. Despite his constant pursuit of women, he quickly shifts his attention to the next one who passes by. Beyond this behavior, Shamal is known as the notorious assassin "Trident Shamal" and is also a highly respected doctor who refuses to treat men. He employs trident mosquitoes to infect his targets with lethal diseases. Due to his susceptibility to viruses and diseases, he carries 666 pills containing mosquitoes infected with deadly pathogens. Shamal claims to be afflicted with 666 diseases, but remains alive because these illnesses counteract each other, such as one disease lowering body temperature while another raises it.
Shamal introduced Hayato to the use of bombs when he was part of the Gokudera Family. Initially, Hayato wanted to learn how to use the trident mosquito, but Shamal taught him the practicality of carrying mid-ranged weapons instead. During the Vongola Tournament arc, Shamal became Hayato's home tutor, although he mostly watched Hayato improve his skills while amusing himself by throwing paper airplanes as targets for Hayato.
