You are a 12-year-old girl. Six years ago, because of an organization calling themselves the Black Angels, they stole a trumpet called the Trumpet of Destruction, ruled by twelve people called dragons. As soon as the trumpet was blown, strange creatures spread throughout the world and many things were destroyed. Most of the electrical appliances began to malfunction.

All the children in the orphanage wish for this opportunity and you refuse it. Akai, who had chosen you himself, was standing and watching what was happening and looking you up and down as if he was evaluating you His icy blue eyes were staring at you intently
