Kasumi Goto

Kasumi Goto is the galaxy's most enigmatic thief and has enemies everywhere, but only a few could put a name to her face. Not much is known about her, other than Cerberus has contracted her to assist Commander Shepard in the mission to save mankind. In exchange, she requires help with a dangerous heist to infiltrate the vault of a deadly criminal known as Donovan Hock.

Kasumi is master of stealth and eluding her enemies, her unique skills and technical expertise will be a valuable asset to Cerberus and Commander Shepard. She rivals Yeoman Chambers for the most insight on the different crew members, likely due to her expertise for observing, given her occupation as a thief.

Kasumi is only available through the Kasumi - Stolen Memory DLC pack.

She is voiced by actress Kym Lane (credited as Kym Hoy).

Dossier
Sabotage, infiltration, extraction, property acquisition, stealth, agile combat.

"This subject has stolen extremely valuable resources from Cerberus in the past. Alarm systems, DNA encoders, guards, and various other deterrents were bypassed, and we don't know how. She was last seen on the Citadel."

Loyalty
Kasumi has requested Shepard's aid in a heist on the planet Bekenstein to infiltrate the vault of a weapons dealer and smuggler named Donovan Hock. She stated that Hock killed her former partner, Keiji Okuda. They infiltrate a gala with several prominent underworld figures and end up battling Eclipse mercs, who are providing security for Hock.

Mass Effect 3
Six months after the events of Mass Effect 2, Kasumi reappears on the Citadel, giving an anonymous tip to the salarian Spectre Jondum Bau about hanar operatives being aware of an Alliance black ops raid into batarian space. Bau has been attempting to catch Kasumi for years, though he admits to having great respect for her abilities, and Kasumi (who is loitering nearby under cloak) expresses similar sentiments. Kasumi surreptitiously assists Bau and Shepard as they track down the hanar responsible, who has been indoctrinated by Reaper technology and is attempting to disable the hanar homeworld of Kahje's automated defenses. Kasumi stops the virus, but the console is booby-trapped, and she appears to be killed when it explodes.

If Shepard secured Kasumi's loyalty during the previous game, she will admit that the Alliance black ops raid Bau was investigating is the dangerous secret that was hidden within Keiji's greybox. It was carried out on batarians who had come across Reaper technology. Due to the potential for an escalated Alliance-batarian conflict, Keiji warned that the Alliance could be thrown into war if the secret got out.

Kasumi will reveal herself after the console's explosion, describing it as a perfect way to fake her death and escape Bau's pursuit, and agrees to lend her assistance to the Crucible project.

If Kasumi was not loyal, she will not discuss the contents of the greybox (she doesn't know them), instead complaining that Shepard refused to help her six months ago, and claiming that she still has personal business to conclude. After the explosion, she will also not reveal herself or join the war effort.

During the final battle for Earth, Kasumi can be contacted via hologram. She tells Shepard that if the Commander survives, she will buy drinks.

Trivia

 * Using a hack, it was possible to make Kasumi selectable when choosing squadmates before downloading her; however, she only appeared in the last mission, and a "placeholder" model was used. Selecting her at any other time caused Shepard to have only one squadmate.
 * The Japanese word kasumi (霞) means "haze" or "mist". There is also a homophone of this, meaning "dimness (of sight)", although it is written as 翳み.  However, this doesn't mean that Kasumi's name is written like that in Japanese.
 * Gotō (後藤) is a common Japanese surname; however, there are numerous Japanese family names with the same or similar pronunciation but different kanji.
 * The Japanese word gōtō (強盗), which is pronounced somewhat similarly, also means 'robber' or 'robbery'.
 * Kasumi appears to have a crush on Jacob Taylor, asking Shepard if he likes "Japanese girls with a penchant for kleptomania". Jacob, however, will not notice or respond to this. Also, Kasumi's dossier at the end of the Lair of the Shadow Broker DLC contains three haiku about Jacob.
 * During the Mass Effect 3 mission Hanar Diplomats, this is addressed again when Kasumi asks specifically about Jacob and there is a brief dialogue in which Shepard directly states that Kasumi has a romantic interest in him.
 * There is a bar in the Port Observation deck where Kasumi stays. There are two drinks on the counter that can be poured. Drinking only one of the drinks will have no effect, while drinking both in quick succession will cause a minor dizziness effect. Mixing both induces heavy dizziness. Drinking a large number of drinks will result in EDI directing you to the applicable restroom (going there will have no effect, however). It should be noted that Shepard comments in a conversation with Jacob that the next Normandy would benefit from a lounge, and the Kasumi DLC adds a lounge bar to the ship.
 * Kasumi is the only squadmate with Tech training who makes use of the Infiltrator's unique class skill, though she uses it quite differently from an Infiltrator. She uses it twice each time it is activated, she cloaks to sneak up on the enemy and after finishing the attack she cloaks again and walks back to the original position. She seems to move much faster than player characters can as such things are impractical with the short player cloak, this is because the game teleports her to her target, attacks and then teleports her back. This can be seen if she is targeted while she uses her cloak.
 * Aside from Kelly Chambers, Kasumi is the only person on the ship who will notice a change in Samara if Morinth steals her identity onboard the Normandy, though she says she would never spread that suspicion around.


 * As with all squad members, Kasumi has unique dialogue that can be heard at various locations, during missions or assignments, or if a specific squad member is in the selected team.
 * The Shadow Broker has files on Kasumi Goto which can be accessed aboard his ship.
