I Want to Go Home With You - S1.E7

Felicia was asked to join the Wings of the Magius, an organization that works within the shadow of rumors. She betrays Iroha and her friends and joins them. Kyoko is also invited by the Wings of the Magius and decides to join the organization. Iroha and company track Felicia down to an underground waterway, where the Wings of the Magius lurk. When the good luck count from the Lucky Owl Water reaches zero, it is said that unimaginably bad luck will befall whoever drank it.
