Crevice In The Crystal

Yukina Uchiha, the sister-like cousin of the legendary warrior Madara Uchiha, also referred to as the Uchiha Princess, her family and clan consistently doting upon her from birth due to her young age and innocence. When an accident occurs in her youth due to her newly awakened powers, Yukina, frightened of becoming a pariah and creating more conflict, becomes an individual willing to do anything to be wanted by others. Therefore, she trains and fights for over a decade, obtaining complete control over her abilities and becoming a high-standing member of her people.
Konohagakure proceeds to bring on further challenges than any Yukina has had throughout her life, caring for her few remaining family members and establishing many necessary systems within the village. All of those appear so insignificant compared to him... Tobirama Senju, the younger brother of the First Hokage, Hashirama Senju, and her fiancé, their arrangement being for the security of the alliance between their respective clans. The two must set aside their differences and prejudices for peace, filling in the crevices they uncover within each other as they reflect their qualties and shine them across their nation.
