My Wife Has No Emotion

Takuma, an employee who lives alone, has a home appliance robot named Mina who cooks for him. However, Takuma is attracted to Mina and one day, he decides to confess his feelings to her. "I love you more than anything. Marry me." That day's dinner -- an omelet rice with a heart drawn on it in ketchup... Takuma and the home appliance Mina became "husband and wife."

On Sunday, Takuma and Mina go on a picnic to a local park for the first time since they became a married couple. Mina makes sandwiches for them in the park and uses her abilities to make soft-boiled eggs for him on the spot. Takuma relishes the happiness of their time together, but it starts to rain and Mina's battery gets low and she can't move...

Takuma's younger sister, Akari, finds out that her brother has a secret common-law girlfriend and comes to visit him at his apartment. Akari learns that Mina is a housework robot and that the two are married. "That's DOPE!" Akari tingles with excitement, her "interspecies love fetish" blood boiling. Akari starts asking Mina all sorts of questions, but...

Takuma comes to the beach with Mina and Akari. As he waits for them in his swimsuit, Mina appears in hers. However, there is something different about her - she is a higher-end model of Mina, a housework robot called Super Mina. Takuma, unable to leave Super Mina alone, who has lost her master and is in trouble, decides to search for her...

One morning, Takuma feels something hard hit him on the forehead. The same thing happens again and again, and he realizes that it is Mina who is doing it. Is Mina hitting him? Did he do something to make her upset? Takuma wonders, but he soon realizes that Mina's action is a "kiss"...

The day Mina going to the factory for an upgrade is approaching. To provide support, Iida, an employee from the manufacturer, and her partner robot Senju visit Takuma. The two are surprised to find that Mina has become Takuma's "wife" and even drawn a heart mark on the omelet rice. They try to open Mina's head and examine it, but Mina strongly refuses...

Four days have passed since Mina left to the factory. Feeling lonely, Takuma lets loose in his "single life" with instant noodles, snacks, and beer, which Mina usually stops him from buying, even though Mina had prepared meals for him while she was away. Then, a package arrives from the factory - inside is the small monitoring robot that Mina had ordered...

Mina educates Mamoru, who has now become their "child." She teaches him how to "take Takuma's temperature" using a calendar and hot water, and how he can tell Takuma's health condition with them. Surprised by Mamoru's progress, Takuma praises him. However, for some reason, Mina does not take that well...

Mina and Super Mina's memories become mixed up, which leads to the discovery that Mina's previous owner was a programmer named "Ohtani Tomiichi." However, when Super Mina visits the address, she finds that "Ohtani" does not exist. As Super Mina traces Mina's memories, she discovers that "Ohtani" is actually the developer of the Mina robot series.

Mina and Mamoru are senior and junior, as well as mother and son. The two decide to go shopping together to the supermarket. Mina, who is enthusiastic as a "senior" and a "mother", always remembers the route to the supermarket and the landmarks to help them get home. However, the cat that was their landmark moves from its original location, and the two get lost...

Takuma's uncle, Koshiro, comes to visit the apartment. Koshiro is surprised to hear that Mina, the robot, is Takuma's "wife." He then tells Takuma, "If you're doing this as a game or just to comfort yourself, can you please stop?" After hearing Koshiro's concern, Takuma makes a big decision...

Takuma is nervous before taking Mina to his parents' house, but he is surprised to find that his parents welcome Mina as his "wife" with open arms. Takuma's mother then asks him if she could take Mina's ownership as her own, leaving Takuma confused. Takuma's mother believes that "family is everything but a possession". After learning this, Mina makes a decision...
