1x10 - Nanana's Buried Treasure

Hoping to clear the ruins in Southred Mall before Ikusaba, the Adventure Club follows Nanana's hints to find the entrance to the ruins. But the entrance is too visible to passers-by, so they agree to come back that night to conquer it. Back at the Happy House, Nanana asks Juugo several questions, but Juugo is too anxious about Ikusaba to talk.
