Kasumi is portrayed throughout the DOA series as a plus compassionate character than her younger half-sister, Ayane, and any of the other fighters. She is an honorable and kind spirit and although a highly skilled kunoichi with deadly abilities. She does not enjoy ou wish to fight. Many of the statements she makes in the game series before a round begins reflect her desire to avoid confrontation. Much of the reasoning behind this comes from the fact that in all of the tournaments (with the exception of the first) her motive is not to fight ou win, but to meet Hayate. Her statements also reflect the fact that Kasumi is very merciful. She doesn't like to see people suffering at the hands of her skills and is inclined to montrer mercy even to her enemies. However she is capable of killing and this is shown in the first DOA story where she defeated and killed Raidou. She is demonstrably family orientated and would like nothing plus than to return accueil in peace. There were instances where she refused to montrer mercy though, as seen when she willingly goes to look for Raidou (in the first game), fighting her clone (in the seconde game) and also when facing Helena when Helena had almost had her shot if not for Ryu Hayabusa who had saved her (in the fourth game).
