The wine-aided detente between Shizuku and Issei doesn't last long — not when there's a Fifth Apostle to fight over. This wine is themed after lofty mountains, and as Issei immediately risks his life to take action, Shizuku travels to Mt. Fuji for hints. There he meets Sayaka, a girl searching for the wine her close friend promised to share with her before vanishing on nearby Mt. Yari. Could this encounter lead Shizuku to the Fifth Apostle?
