Some time ago, the technology of "smart threads" was created, which allowed to get rid of the consequences of viral encephalitis infection, which became widespread. As of 2023, the use of this development has become commonplace. However, these devices have features that can be perceived as a disadvantage. They remember the slightest actions of their owner, be it a glance or even an emotion. And at the same time, this is a useful property, as it helps in crime investigations. Electronic investigator Ethica Hieda uses the invention "Your Form" to dive into people's memories.
The girl has succeeded in her work, but her assistants suffer because of her perfection. They cannot keep up with the pace she sets and end up in the hospital as a result. The management believes that Ethica cannot be left without a partner, and for this reason, they assign android Harold Lycraft to her. However, he has a terrible character, and it is difficult for them to work together. Moreover, they also have suspicions towards each other. Meanwhile, a technological infection begins to spread around the world, and the heroes must take action.
