Kunihito apologizes to Kuniko for his apparent betrayal, holding her off while Ryoko escapes to the Eternal Forest with Mikuni. Enraged, Kuniko attacks Kunihito, only to be stopped by Momoko who arrives to tell Kuniko of Kunihito's true motives. It's revealed that Sayoko survived her fall from the upper deck because Momoko intercepted her descent. Ryoko arrives in the chamber once occupied by Hiruko, revealing a hidden passageway into the bowels of Atlas itself. Shogo, Leon, and Sion attempt to stop her, but she eludes them and they descend down through the shaft. Sayoko is quick to follow.

A rather comical chibi battle ensues and Karin is knocked into a separate field, greeted by the teddy forms of her parents, who reveal the real reason as to their extended absence. It's only a virtual program operated by Ryoko, but it turns out that Karin's parents had died three years before. Karin suffers a breakdown and Ryoko returns to reality to command Mikuni to draw the bejeweled spear and assume her role as successor. Mikuni, however, refuses, but after th
