Sister Maria (マリア姉 Maria-shi) is a sub character in 11eyes: Resona Forma, If Story arc. She is said to have come from Ephesus, and has been believing in the original teachings of God for a very long time. Her belief seems to even surpass those of the oldest believer generations, but she is far from being extremist. When Lisette tried to sneak a little food for her savior, Maria did not scold her but encouraged her, as she believed that Lisette should repay the kindness she had received.
- Sister Maria is implied to be Johanna herself, partly because they have the same voice actress, and mainly because Ephesus is also where Maria Magdalene died.
