You may be wondering about the title, me too. It's a song by Melody Day. lol this 'description' is not really saying anything about the story so I might as well stop typing this.

There were two prophecies that God gave mandkind before he went missing. A child shall be born on darkest day and another on the brightest night. The forces of heaven led by the Aegis Council and the forces of hell led by the Masters of Hell are getting ready for when the children of prophercy will bring either prosperity to earth or the Apocalypse.... Staring the members of Hey! Say! JUMP, NEWs, KAT-TUN, Arashi, ABC-z, Yamashita Tomohisa, Akanishi Jin, Ito Hideaki, and more Johnny's Entertainment's talents as reference. Also staring a few Original Characters, Chinen Yuzaki, Hongo Akira, Kusanagi Aya and a few more..
