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."
Don't mess up my wedding dress, please.
.لا تفسدوا ثوب زفافي من فضلكم
Macht mein Brautkleid
nicht schmutzig.
"No arruinen mi vestido de novia, por favor".
"No echéis a perder mi vestido de novia, por favor".
Ne salissez pas ma robe de mariée.
Por favor, não sujem 
o vestido de noiva, tá?
