Sapphires and Emeralds (MikaYuu)

Warning: Swearing, blood, gore, may include sexual themes.
Yandere!Mika is included. You have been warned.
8 years ago, Yūichirō , a rowdy and anti-social ravenette came to Hyakuya orphanage. Mikaela, a kind, yet strangely haughty, champagne haired boy deemed it his job to make the new boy part of the small family they had. A horrible accident occurred and Yūichirō watched his whole family die, including the one he loved the most. Thinking he was the only one who survived he swore to eventually get revenge, somehow , but what may seem false, may just be the only truth.

MOST CHARACTERS DON'T BELONG TO ME. THEY BELONG TO THE ANIME OWARI NO SERAPH (SERAPH OF THE END). SOME WHO MIGHT DIE ARE MY OC'S TO KEEP THE STORY GOING.
