God, does a god really exist in this world? While worrying about her spoiled younger sister, Ruruna, who is being doted on and pampered, Sasami decides to send her to elementary school. Concerned about Ruruna, she decides to peek into the elementary school using a "monitoring tool." What unfolds there is an incredibly bizarre and violent class on "Norse mythology"!? Humans who consumed the forbidden fruit of wisdom and were cast out of paradise. Is it a trial or folly to abandon an innocent heart and read the heart of a god? What punishment awaits the young gods who dare to peek into the forbidden abyss by seeking to know the future and uncover the past? Starting in January 2013, an anime produced by Shaft and directed by Shinbo Akiyuki (known for works like "Bakemonogatari" and "Puella Magi Madoka Magica") with an incredibly luxurious staff will also begin airing. The series is reaching new heights with its 10th installment!
