touma heard a voice calling to him that day – a voice calling out to him in a dream. that day, sousuke forsook his family, escaping with the sword that they had guarded for generations. touma's dreams weren't supposed to mean anything once he woke up; sousuke's family wasn't supposed to find him or the sword ever again. but once they meet, fate binds them together – and fate has a funny way of sending all such plans awry.
