Necromancer

Nekuromansā (ネクロマンサー)

When Michiru hands Nana the photo, Nana convinces Michiru that Tsunekichi was not as clairvoyant as he claimed. Afterwards, Michiru reveals that she tried to resurrect Tsunekichi. At Tsunekichi's funeral, Kyōya requests that an autopsy be performed. However, Nana takes him outside where they have a conversation. When they return to the funeral, Shinji Kazama uses his necromancy to control Tsunekichi. The next day, Nana approaches Yūka Sasaki about Shinji. Later, Yūka explains to Nana and Kyōya that she rescued Shinji five years prior using her super strength. 

In the infirmary, Nana pretends that she is tired so she can sneak out and kill Shinji. After she poisons him, Nana rushes back when she notices the cat is stuck in a drain. She then gets Kyōya, Michiru, and Yūka to help her. However, Yūka claims that she is allergic. That night, Nana attempts to kill Yūka when she is stopped by Shinji. Nana then realizes that Yūka is actually the necromancer. After Yūka reveals how Shinji died, Nana admits that while she is a murderer, she lets the dead rest in peace.
