She appears in Volume 25, inside a cave of the artificial Yggdrasil, waiting for Issei and his team to arrive, with Asia Argento and Grayfia Lucifuge staying behind to become her opponent while allowing Issei and the rest of the group to proceed.
The fight between the two female devils and the goddess was even until Asia summoned Fafnir who in turn summoned an army of mini Fafnir's to attack Artemis and try to steal her underwear. Their fight continued without a clear victor until the end of the Rating Game where Team Leisure of Kings was defeated due to Typhon's resignation at the hands of Ddraig.
