1x9 - Muhyo & Roji's Bureau of Supernatural Investigation

The one who ripped the talisman off the bottom level of the magic prison was the spirit of a little girl named Sophie, nicknamed the Face Ripper. She has taken on the guise of someone in the magic prison using her ability to mimic others by stealing their faces. Just when they find out who she's turned into, Sophie reveals her true self... but Muhyo is still asleep after using too much magical law earlier. The others force him awake, but his only option to defeat the powerful Sophie is to use high-level magical law...
