Report 203

Plot
The third term begins, with Ohga and Hishiro as the class representatives this time. Kaizaki managed to barely pass all subjects, so there'll be no more re-tests for him. With less than one month of school left for the seniors, Kaizaki and Hishiro each feel a bit of melancholy.

In the ReLife Laboratory, Yoake overheard Amagase explaining how the ReLIFE memory loss works to the Division Chief. The first pill each participant took contains a virus-like mechanism, and each person's "virus" is unique. The people they come into contact with gets "infected", and at the end of the experiment, the "virus" would cause infected people to lose memories of the carrier. ReLIFE employee are "vaccinated" against the "viruses" of the test subjects, and the test subjects are also "vaccinated" against the "viruses" of the employees. Therefore they will remember each other even after the experiment is over. But test subjects 001 and 002 were not "vaccinated" against each other because the need was not anticipated. By now Kaizaki and Hishiro would have accumulated way too much of the other person's "virus" and there's no safe way to remove those without risking harm to the person.

Yoake's boss realized something comparing the memory loss mechanism with flu or common cold...
