Haru has the ability to manipulate or otherwise interact with matter or another aspect of a physical system through non-physical means. Commonly, it's most basic trait is to move and control objects (or generate and apply physical force to a target, or potentially to an area, if he is focused) without physical contact.
Haru was taught from childhood to master several martial arts skills by his father or other temple guards. He can perform martial arts using his bare hands or his spear.
Haru has the ability to manipulate, create, or shape water. He can manipulate the liquid or solid form of water. He can use water-related weather such as blizzards and rainstorms. Sometimes he can also control the water temperature as he will.
As someone who can manipulate water, Haru can manipulate water to heal minor and major injuries.
