S1·E3 Masked Mansion

Rie calls on Shinjūrō and Inga to accept a request from Mitsuko Sasa, whose adopted brother Kazamori caught on fire and died, allegedly related to a curse from her father, Komamori, who died in a similar manner seven years ago. As Izumi's group conducts their own investigations on the cause of Kazamori's death, Inga uses her powers to reveal that Kazamori is actually a supercomputer.
