Tatsu Hinata. Her name meaning dragon. She had a bad life. She never knew what the word 'Love' meant. But that changed when her baby brother came into the world. She suddenly had a reason for living. She changed when Shouyou was born. She finally understood what love was. From then on she fought with everything she had to protect what she loved.
Time-skip forward to current:
A lots happened in her life. But finally it was peaceful. But nothing could have prepared her for what was about to come.
(Starts from beginning of the OC's life, so you can understand later on. Original character centric in the beginning. But once we get caught up to present it will show others point of view more often.)
