My best friend was killed in a motorcycle accident. He was eighteen - years old like me when he died. I was invited to a lagoon and I decided to summon Jesse's spirit while I was in the water. I didn't know how to swim and I almost drown while calling for Jesse. The moment I reached shore a strong realization came to my head. The only way that I could see Jesse again was by being dead like him!

People tend to summon a loved one when they die. Sometimes the right soul or spirit hears the summoning; but sometimes is an evil entity. A Sentinel is in charge of guarding human souls. My name is Leila and I was named an "Earth Sentinel" by my dead twin sister Lia. My mission is to battle those entities with the help of an attractive nineteen-year old Earth Sentinel named Max and his sister April.
