Following the events of their trip to Okinawa, Saitama University graduate students Shinya Yukimura and Ayame Himuro have failed to obtain the data necessary to scientifically prove their love for each other. Unable to replicate the exact conditions of the trip, the two stubborn scientists decide to seek help from elsewhere in the university—the Biological Sciences department. Assisted by fellow graduate students and longtime couple Chris Floret and Suiu Fujiwara, Yukimura and Himuro begin to quantify their feelings by measuring their output of oxytocin in various romantic situations. The two scientists soon find that their feelings for each other are nothing compared to that of a mature couple. It is here that Chris poses a question to both Yukimura and Himuro: what will they do if their affection is proven not to be love after all? Desperate to find a scientific rationale for the discrepancy, Yukimura puts everything on the line to prove that their love is real.

It is widely believed that science can provide rational explanations for the countless phenomena of our universe. However, there are many aspects of our existence that science has not yet found a solution to and cannot decipher with numbers. The most notorious of these is the concept of love. While it may seem impossible to apply scientific theory to such an intricate and complex emotion, a daring pair of quick-witted Saitama University scientists aim to take on the challenge. One day the bold and beautiful Ayame Himuro outwardly declares that she is in love with Shinya Yukimura, her fellow logical and level-headed scientist. Acknowledging his own lack of experience with romance, Yukimura questions what factors constitute love in the first place and whether he is in love with Himuro or not. Both clueless in the dealings of love, the pair begin to conduct detailed experiments on one another to test the human characteristics that indicate love and discern whether they demonstrate these traits toward each other. As Himuro and Yukimura begin their intimate analysis, can the two scientists successfully apply scientific theory, with the help of their friends, to quantify the feelings they express for one another?

The Z Project was intended to give the new generation a break from caring for the old. The original intenion was to create a machine to care for them without any intervention. At first glance, it looked like an excellent plan, and many of the younger generation approved of its application. But when old Mr. Takazawa become the test subject for the Z-001 machine, Haruko questioned both the tactics of the hospital and the moral implications of the machine. This is just the beginning, as Haruko has not just the hospital, but the odds against her. But then, she discovers an odd quirk about the machine: it uses a biochip, and it eventually acquires a mind of its own! (Source: AnimeNfo)
