Kasumi Nakano

Kasumi Nakano is a runaway mechanic and technical expert taking refuge in Acadia in 2287.

Background
Kasumi Nakano is the daughter of Kenji Nakano and Rei Nakano. She and her grandfather used their mechanical knowledge to restore the pre-War appliances around her house.

After restoring a radio and contacting DiMA by chance, she is led to believe that she is a synth who has replaced the real Kasumi Nakano. This belief is reinforced by her feeling like she does not fit in at home, a lack of childhood memories to the degree she can not remember entire years, being unsure if she used a swingset near her house, and inexplicable dreams about waking up in a lab's white room while feeling a jolt of electricity to the back of her head and being stared at by mysterious people. Although she does have her own doubts as to if this is the truth, she can not prove it.

She later flees to Acadia, although she can be convinced to return after completing the add-on. If Far Harbor, the Brotherhood of Steel, or the Institute attack Acadia, she will die in its defense.

Personality
Kasumi is curious and empathetic, as shown by her pursuit of DiMA's radio signal and her desire to help the people of Acadia. When she was living with her parents, she was frequently bored, as she was isolated from the wasteland in her remote home. Her grandfather's passing worsened this feeling of boredom.

Interactions overview

 * * If the Sole Survivor becomes an enemy of Acadia, Kasumi will fight to defend it.

If Kasumi returns home safely, Kenji's reaction will differ depending on whether or not she believes that she is a synth.
 * If Kasumi believes that she is a synth, Kenji will be angered, refusing to accept anything but his human daughter. The Sole Survivor can convince Kenji to accept Kasumi in spite of this;
 * If the Sole Survivor convinces Kenji, he will let Kasumi remain at the house, especially after Rei says that even if their daughter has been replaced by a synth, they should give her a chance and try to salvage whatever they can in a terrible world.
 * If the Sole Survivor fails to persuade Kenji, he will kick her out of the house. If followed, Kasumi will walk through the Commonwealth, eventually reaching Goodneighbor (via a route passing Parsons State Insane Asylum, The Slog, County crossing, Bunker Hill and Cabot House); being essential, she will survive any attacks on the way. Here she finishes her journey by entering The Third Rail where she takes a seat close to the bar. Her only response is to say that the Sole Survivor has done enough already and to leave her alone.
 * If Kasumi believes she is human, Kenji will be tearfully relieved to have her home and expresses his extreme gratitude.

Appearances
Kasumi Nakano appears only in the Fallout 4 add-on Far Harbor.

Behind the scenes

 * Her first name, Kasumi (霞), means "haze" or "mist," and her last name, Nakano (中野), means "in the field" in Japanese.
 * Kasumi's radio identification is Ohm's law, which describes the relationship between a circuit's resistance, the voltage applied to the circuit and the current flowing through the circuit.
