Sea of Black {Umi~no~Kuro} Ch.1 SAYWAT???

"UGH!!!! I am Bored!!!" Kat said after the last bell rang. Her brother Hei sighed. "Can't you say anything else? That's all you seem to ever say." She punched him in the arm playfully.  He shoved back. They kept there little fight going until they where a block away from their 2-story house on the west side of the town. The wind was blowing slowly. And then Hei sensed something wasn't right.
