Ep 16. The King of the Giants

At the entrance to Thrymheim, the group is determined to succeed in the quest in order to prevent Thrym from invading Alfheim and causing the cataclysmic event Ragnarok to happen. At the end of the second floor, they use elemental magic to power their weapons in order to take down two minotaurs with a great amount of teamwork. After they defeat a giant insect on the third floor, they encounter a woman locked in an ice cage, and despite fearing it may be a trap, Klein destroys the ice cage to free her. Kirito reluctantly agrees for the woman, recognized as Freyja, to join the group. After Asuna recharges and Freyja boosts the group's health, they enter the boss room filled with gold, where they are met by Thrym.
