Kasumi is an expert on sabotage, infiltration, extraction, property acquisition, stealth and agile combat. Cerberus tries to contact her to get her to join Commander Shepard's mission; however, she is alerted and trails Cerberus and contacts them. She agrees to work for Shepard provided the Commander helps her by recovering her partner, Keiji Okuda's graybox from Donovan Hock. Appears in ME2. Kasumi is only available through the Kasumi - Stolen Memory DLC pack. If she gets out after suicide mission alive in ME2, Kasumi reappears on the Citadel in ME3. -masseffect.wikia.com
