Aincrad Arc:

"Many people trapped in a death game? How awful!!! If you die in the game then you die in real life as well. And what's this? A deadly PK group called Laughing Coffin works from the shadows! Is there no end to this nightmare? But there seems to be a vigilante who sends a calling hard ahead of them telling these evil doers that their days are numbered! Who is behind this? Are they friend or foe? Any one is a suspect! Who could it be? It definitely can't be the new restaurant owner who just opened up their shop."

Fairy Tail Arc:

"An evil man sits alone in his office twiddling his thumbs. He is so close to marrying one of the loves of your life. Victory is almost there that he can almost taste it. The problem are these rumors of a weird shadowy organization going around killing evil doers and this man just received a calling card in the mail. But he's one of the most powerful people in the country. He has nothing to worry about. Sure he's losing investors fast for some reason and many of his friends have been announced missing but all of this will be worth it. There is nothing a high schooler who is worried about their exams can do to stop him"
