This is a crack ship, so read at your discretion: Nura Rikuo x Natsume Takashi.
Their meeting was fate, but they only met once. At the time, one was human and the other was a yokai. He later learned that he was a half-yokai, with a human mother and a half-yokai father. He couldn't even be considered a half-yokai.
He was drawn to him.
P.S. This story came from a sudden idea the author had, so there may be OOC moments. If you find any plot holes, consider them headcanon.
