Kasiri is shown to be fierce and territorial, with a short temper. She seems to have a dislike for Lycanrocs as seen in the episode, Master Thief, though this is because they invaded her Home.
Kasiri is noticeably very grouchy and is no stranger to the odd bout of sarcasm. She becomes incredibly angry when her sleep is interrupted. She is also extremely protective of Auni because of her blindness and rarely leaves her alone.
