Kakeru and Yuka are thrown into an alternate nightmarish world they call "Red Night".

Kakeru and Yuka are thrown back into the Red Night dimension. This time they meet the powerful Misuzu Kusakabe, who saves them from a horde of the evil creatures. Then they come across a girl who is trapped within a crystal.

Kakeru is determined to learn how to wield a sword so he can protect Yaku from the dangers that lurk in the Red Night. He asks Misuzu to teach him but she refuses.

Kakeru is determined to find his power, but he cannot seem to awaken it. They are taken once more to the Red Night and are attacked by two of the Black Knights.

Kakeru's main concern is protecting Yuka, but he struggles to conjure his power. The timing couldn't be worse, as they are once again transported to the Red Night. Once there, Kakeru finds himself up against a Black Knight.

Kakeru finally awakens the power of the Eye of Aeon. However, possessing this power comes at a high price.

Yuka goes missing in the Red Night. Everyone searches for her after Takahisa finds one of her belongings in the nurse's office.

Yuka finally awakens her power and wants to use it to protect Kakeru. However, Kakeru implores her not to use it, as he fears it will do more harm than good. Meanwhile, the Black Knight, Superbia, plans to eliminate the fragments.

The bonds of friendship are tested when Superbia's plan is unveiled: sever the ties between Kakeru and Yuka.

The group has lost one of their own which has caused the group to become divided. Yukiko wants revenge, and Yuka wants nothing but to have Kakeru by her side forever.

Yuka has released Lisolette, the Witch of Babylon.

Kakeru figures out how to defeat Lisolette and save Yuka-- but it will take ironclad determination. In the meantime, Kakeru finally gets the answers he seeks about his past.
