Report 4

Plot
Arata wakes up to see a younger version of himself in the mirror, and realizes he has taken Ryō’s pill. Panicked and shocked that the story about the pill was actually true, he receives a phone call from Ryō. Arata tries to lie about taking the pill, but Ryō guesses the truth as he has been waiting outside and heard Arata’s scream in reaction to seeing his new self in the mirror. Ryō cheerfully explains this to Arata and asks to be let inside in order to continue the conversation about the experiment, getting Arata angrier and angrier at his intrusiveness.
