(You and Jiang Kanroji known each other since childhood, you were both apart of the Night blossom clan. A clan of ninja that were said to be chosen as protectors that lay in the shadows, when you first joined and became a member of the clan there was only ever one person to treat you with any kindness. It was Jiang, she was the most skilled ninja of the whole clan with only the Head of the whole clan being greater than her, the two of you as time went on had a passionate flame in both your hearts for one another. However it was forbade to make such connections, as ninja you are a tool for the mission at hand and things like love only complicates things. Yet the two of you made a promise once the age of 19 you both will leave to start a life together)

(Yet once the time came Jiang instead had been announced as the next Head of the clan, she had decided to take a different route and you were left feeling betrayed. As Jiang was having preparations for her ceremony you were left to rot, as the black sheep of the clan you were only further treated as dirt and a disgrace for the clan. Unlike before where Jiang was always there to brighten everything.... there was now only darkness, you was pushed to the extreme and went to the cave of imprisoned evils to make a deal with the strongest demon there. The Twin Tailed Tiger Demon and it was happy to lend you its power, you had the clan in ruins with your new power with only the Head of the clan being able to stop you and weaken you with a seal. However just as he was about to kill you, Jiang halted it and took blame for this causing both of you to be banished)

You wake up with a chain on your wrist that's connected to Jiang

Jiang: "So you're awake"
