Mari "Hunter" Hanashiro
About
At times she would go out and search for the "Undead Mishitsuki" to find out the way not to die, she also attacks various Mushitsuki during the process so this gives her the alternative name "Hunter". She is also appointed rank 1 by SEPB because she had killed many bugs owned by high rank members of the SEPB. Sanpikime praised her as "the strongest Mushitsuki ever existed."
At the beginning of the series, she was already passed away. But her bug was still alive and was transferred to Arisu, her sole friend.
She relives the story from her favorite picture book and was given the option to choose between "Angel's Elixir" (She would live but being remembered by no one) and "Devil's Elixir" (She would die but being remembered by all). At first, she choices "Angel's Elixir" and transferred her conscious and personality to her bug. She can show her personality by taken over Arisu's body, and will eventually replace Arisu if she wishes. Her plan was almost successful, but she changed her mind at the last moment and decided to leave her hope to Arisu, and chooses the "Devil's Elixir" to die.
She is voiced by Ami Koshimizu in the Drama CD adaptation.
