Aa! Megami-sama!

Synopsis

Keiichi, unable to meet directly with Belldandy, apologizes and continues to work. Despite Urd and Skuld's efforts, they cannot find a way to remove the bugs created when Belldandy and Keiichi are too close. They resort to the Ultimate Magic Circle, a forbidden magic, as a solution. Keiichi eventually earns enough to purchase the ring. The sisters complete their research of the Ultimate Magic Circle. Belldandy, crying, removes all traces of herself from the temple and begins to depart through the gate. Keiichi arrives as she is departing and Urd casts her spell, closing the gate. Keiichi and the goddesses are thrown back in the ensuing explosion and Belldandy enters Keiichi's consciousness to save him. Keiichi's memories begin to return and he realizes that Belldandy made a forbidden promise, forcing her to seal all of Keiichi's memories. When he finally wakes up, The Almighty rescinds his order for Belldandy to return and Keiichi gives her the promised ring.
