2 - 4: The Challenge from PSY

Aichi goes with Misaki and Kamui to Card Shop PSY to ask the owners if they know anything about his suddenly-switched deck. Rekka, Kourin, and Suika are about to go on a trip, but Rekka finds time to taunt Team Q4 for letting their skills stagnate since the national tournament... and to prove it, Rekka debuts her Angel Feather deck as she takes on Misaki!
