The Life of a time traveler with a immortal.

The life of being a time traveler sucks, I know. As Iha Amaya being the most and precise time traveler ever. As her life changes when she accidently met a immortal, nobody knows his name until she finds out about his life and nobody exactly know why, really. But will she actually finds about it, really? Only 'certain' people knows about it and it is her, he will find out about this. She was one of the people knows it all, because of that, he was willing to die whenever he has time to die. He will always die for her and be the same for her.
