Reiko Tamura (田村 玲子, lit. Tamura Reiko) is a Parasite who, coincidentally, infected Ryouko Tamiya (田宮 良子, lit. Tamiya Ryōko) and one of Shinichi Izumi's high school teachers. Just like most other parasites, she has an emotionless expression. However, after giving birth she became increasingly maternal to the point that she gave her life to save her son.
In Reiko's first appearance, she had shoulder length light purple hair and sharp brown eyes with bags underneath them. She had an average height and a slim build. Students, mostly male would comment on her good looks.
With her second appearance, her body type remained the same, but her skin became fairer. She now had long black hair and a more pointed face. Her expression changed to one that was calmer and relaxed. She was often seen wearing formal attire and lipstick.
Reiko was a highly intelligent parasite as she often studied the human psyche in hopes of understanding their species better. She was initially just as cruel as her fellow parasites. After giving birth and raising her child, she began developing and showing human emotions, such as laughter and love towards her son. She sacrificed her own body to keep her son safe, as the police shot a barrage of bullets at her. Before succumbing from her wounds, she revealed that she truly believed humans and parasites to be the same and that she enjoyed the time she had spent living as a "human". Her death causes Shinichi Izumi to start crying after a long time of inability to cry.
After the Parasite took over Ryōko Tamiya's body, the Parasite took the name "Reiko Tamura". Reiko has scientific inclinations and is driven to discover the biology, origin, and purpose of Parasites. Reiko discovers—by becoming impregnated by another Parasite named Mr. A—that a pregnant Parasite will bear a normal, human child, and that Parasites have no apparent means of reproduction. Reiko is more logical and reasonable than many other Parasites and allows Shinichi Izumi to live unmolested largely because she finds him an interesting anomaly worthy of study.
When Ryoko's mother learns that her daughter just quit from her post as a teacher, she went straight back to Reiko's home to see if she was alright after what happened. She then realizes something different about Reiko, that her personality has become bolder. Her mother confused that there is something wrong with her daughter Ryoko, attempts to call the police. However, before she can contact the police, Reiko morphs and beheads her.
She eventually gives birth to Mr. A's baby. She hires Shiro Kuramori to spy on Shinichi, to see if anything changed. After betraying her fellow Parasites and killing quite a few of them, the police brutally kill her. The baby survives because of her decision not to fight back against the police and her son was adopted by another family.
Abilities & Powers
As a parasite, Reiko has the basic abilities to shapeshift her head and maximize the physical potential of the body she's controlling. She can harden her cells for offensive and defensive purposes.
Her high intelligence allowed her to make use of unorthodox tactics when engaging enemies. When targeted by three of her own kind, she tricked them into believing she had gone insane when she split her parasite in half. Believing her to be suicidal, she was able to lure away Kusano, kill Maesawa by allowing the parasite to burrow and destroy him from within and then trick Kusano into killing Hikawa by burrowing into her and forcing her to attempt to kill Kusano. He kills her, allowing Reiko to sneak up on him and kill him when he unintentionally jams his ability to sense other parasites when he hacks Hikawa up.
While in the Live Action film, she can able to split her parasite in three, using them to pierce the heart of three of her own kind from behind, killing them without letting them notice. She can also extend her hair and wrap them around her son to protect him from the police's gun shots.
In addition, her intelligence and interest in the human mind allowed her to more effectively blend into society.
