Эпизод 4

Finding themselves in an unusually empty cafe, an old Android walks in. Upon questioning the android they find out that its name is ****, further questioning leads them to find out that it also doesn't know the address in which it worked, nor the name of the child it was looking after. Confrontation of these issues causes a logical error and the android shuts down. Nagi concludes that it was illegally abandoned to skip on paying the return fee and all personal data was deleted to prevent anyone knowing who abandoned it, and before it shut down it wanted someone to remember its name.
