Twenty years prior to the game's timeline, Tae used to work for Toue as a researcher. As a part of the original researchers of TOUE Inc., she witnessed the growth of the company little by little. Tae specialized in the brain's plasticity and tested drugs that affected brains that had lost their functionality. Tae was facsinated at neural research and hoped one day to be able to find a solution to save people who had damaged brains. Tae was the founder of the theories of Aoba's and Sei's powers. However, she had no idea that her research was to be used to engineer children who had the power to control people's will. She later discovered and was ultimately horrified that a child, Aoba, died due to her research. Tae escaped the facility with Aoba inorder to give him a proper burial as a human being. Despite it all, Aoba came back to life and Tae was both astonished and overjoyed. Tae then left Aoba in the care of a church located in her hometown. Upon finding out the company's true interests, Tae stopped all of her research and quit her job. She then lived peacefully in Midorijima leaving Toue behind her. Her daughter, Haruka Seragaki, met Nain and fell in love. Nain having a knack for travelling decided to take Haruka with him by force. Tae was suspicious about Nain but when she saw that Haruka was completely devoted to Nain she realized he had some sort of miraculous power. Tae accepted him and allowed Haruka to leave the island. The couple returned later on and brought Aoba with them. Tae recognized the child right away and believed that it was fate that Aoba would return to her after leaving him in the church's care. Later on, she was contacted by Toue, requesting her return immediately. However, she adamantly refused him and as a result Morphine was put into action.
