Prologue
There was a boy who transcended all. A psychological genius, who could read your mind and who could also play your heart. He was a benevolent soul, one who won the Liar Game- who was the top participant. He was only of 10 years old. He was kind and one who was full of smiles- seeming naive even, but was unmatched in the strength of the game. But as soon as he won the game, he disappeared. The existence of Seiko disappeared, along with the stopped filming 18 years ago.
Hayashi Riho is a normal investigator with just one abnormality. Her photographic memory. Her memory and personality earned her a place as one of the top investigators in the Osaka region. But there's one thing the others don't know. She suffers from an abnormal case of MPD. It's not the disorder itself that is odd, it is the times when she has her split personality.
So then what happens when this girl receives an invitation to the Liar Game? Will she meet Akiyama and Nao? And what exactly causes her split personality?
