Love is the most powerful emotion. Love can move mountains; it can save lives, or change the world. Love can defeat destiny.
At least, that's what Hokuto has always believed.
It was love that made her move with Subaru to Tokyo, love that led her to believe she alone knew what was best for him.
Out of love, Hokuto protected her brother, watched over him at her own expense. She knew she could find love, but had to set up Subaru first.
Her belief in love made Hokuto push Subaru and Seishirou together, despite everything common sense told her. Love, she knew, would make things right.
It was love, eventually, that led her to challenge Seishirou, caused her to die in her little brother's place. It was her love for Subaru, and her belief that Seishirou and Subaru loved each other. She never considered that they could be in love and not end up happy. Tragic love was not real love, in her mind. Ironic, then, that she should die in a gesture of tragic love, for tragic lovers.
Hokuto's love kept Subaru sheltered for 16 years.
Hokuto's death freed him.
Love is power, but not all power is good.
