The series was created by Masaki Kajishima, produced by AIC and distributed by Pioneer LDC/Geneon, VAP, and Funimation Entertainment.
Note: The English title used in FUNimation Entertainment's Region 1 release of the series appears first, followed by the original kana/kanji and romaji.
Where applicable, a more literal translation of the original title appears after the romaji.
Special: Creation of the Universe Journey across Space-Time, with the exception of Ayeka's tale, which was created for episode 11.
The latter tale was supposed to be on the aforementioned CD, but was cut out due to time constraints.
