Ligaya is a skilled fighter, trained in hand-to-hand combat and martial arts (often being a sparring partner for Reyna), and is trained in fighting with spears, blades and clubs/sticks.
Despite her name meaning "happiness", she is not someone who looks very happy XD She is often very serious with almost everything she does, and she's pretty silent too, only talking when she needs too, and often in very short and simple to the point speeches.
