Dealing with the Devil

At this time, technology was greatly enhanced. But unfortunately, no one invented teleporters yet. In this city you can see many people on their phones and living their normal lives. But there's one thing they don't know. People get messages on their phones saying that they will die today. But they don't believe it so they don't tell anyone and just ignores it. They later found out that they couldn't see tomorrow. From this situation, they formed groups of professional fighters to stop the things that kill them, but they can't stop the death notes. The bad thing about this is that they may die and not live a happy life. It has been 10 years now and there has always been five members in the group. Five different families, each with special skills that contribute to the team. But what makes them unique is the way they can see the spirits when no one else can. One of the family was dying out. The girl keeps on saying that there's no other relative that can take her place. She soon died from a rare disease and the group became incomplete. They are now searching for someone that can take her place for the time being. The question now is will they be able to stop the person behind this or will the death note still continue forever?
