Johanna

The founder and current pope of the Holy Office of Index. She has been the head of Index for almost a millennium, making her the oldest character of 11eyes. For that, some apostles of Index called her Great Mother Johanna out of respect. In addition, Johanna is also known for having been collecting magical items from around the world to prevent them from falling into the wrong hands, thus, giving her the name Johanna of the Vault. Apparently, the most valuable and powerful item that she collected is the God's Name Tablet, the largest fragment of the Emerald Tablet found.
