Misae Tsuji

A woman infected with "Medusa's head". She married a older man and thought she was pregnant, but later found out that her stomach was infected. The protruding veins made a "face", which was familiar to her. She was friends with Misaki Moriya before Misaki committed suicide infront of her long ago. The "face" might've been a omen of what was to come, from a deceased Misaki.
