After the first murder, Shiki's uncle, Director Shindou, is killed as well. The lab is in an uproar. To find out who the killer is, Nishinosono and Saikawa investigate Shiki's room. There they find a robot named Michiru, and a strange message saying "Everything becomes F."
Be quiet! I heard a voice.
.صمتًا! سمعت صوتًا
Leise!
¡Silencio, escuché una voz!
¡Silencio, escuché una voz!
Taisez-vous,
j’ai entendu une voix !
Fermi tutti! Ho sentito una voce!
Façam silêncio! 
Eu ouvi uma voz!
