Neo is reborn in an apocalyptic world, where he would always meet silvia(code name) (mc:Tina) in everylife and everytime she died, she was his friend, lover, strangers, partners, in different lives whenever he was reborn. He blames himself whenever she dies so he always tried avoiding her, but for him it's impossible, as all those memories have haunted him. Neo has a cold personality, often shutting himself away from everyone and has only been seen opening up to his dog, hail.
