It's New Years eve, and Mitsuki goes to a small party at her friend Ruri's place, where she learns a valuable secret about Yuuto's situation. She tries to tell him, but her surpressed emotions start to well up.
A general term for the myths told by the Germanic tribe known as the Norsemen before the arrival of Christianity. 
These oral traditions were first recorded by scholars in the 13th century, in works such as the Younger Edda and the Heimskringla.  It is thought that Norse Mythology describes a universe that consists of 9 worlds and three levels. These levels are referred to as Ásgarðr, Miðgarðr, and Niflheimr, and are inhabited by a variety of god, men, giants, spirits, and monsters.
Norse mythology also contains many prophecies about an apocalypse called Ragnarok. On this day, all of the seals that have ever been laid will be released, and the imprisoned enemies of the gods, such as Loki, Fenrir, and Garm will attack the realm of the divine. 
The gods and the Einherjar (Fallen warriors) will put on their armor, and fight the armies of the giants at the plains of Vígríðr. A long stalemate continues until Surtr unleashes lames that will burn the universe and sink the 9 worlds into the sea.
