"Why is it that you have to be Signal's opponent?" Signal, a rare disease that only a very small number of people are said to suffer from. Since it had nothing to do with me, I just struggled through my busy and difficult daily life... But as always, an ordinary day suddenly became worse than a nightmare. I shouldn't have answered that phone call... How did I end up getting involved with a man whose name I don't even know? "Relax. Since you started first, you should have been able to handle it." No, this is a lie. This is a dream. It can't be real! (Source: Ridibooks, translated)
