A relative of Satō who had taken full custody of her after her parents died many years ago.
It was implied that Satō killed her, as she was only shown in flashbacks. When we do meet her, she's covered in bandages.
Despite her happy and cheery nature, she is actually mentally unstable as well as being deeply insane, and she accepts all forms of desires towards her with disturbing masochistic pleasure. Her deeply twisted views of love are held responsible for making Satō think in a similar fashion.
She lives in the same apartment complex as her niece but is in a different room floor. In the final episode, she is arrested for arson and first degree murder of Satō and Shōko (even though Satō was the one responsible for Shōko's death).
