S5·E12 The Superb Song of the Valkyries

Despite Elfnein and Carol's attempt to stop her, Shem-Ha begins using the world's computer networks to have Yggdrasil cover the entire globe in a barrier. Back on the moon, Hibiki and Chris face off against Vanessa, ultimately saving her and the others from being sucked into space. However, Shem-Ha takes control of Vanessa and uses her to install a virus in the Marduk's network in order to destroy it, forcing Noble Red to use the last of their strength to send the wielders back to Earth, resulting in their deaths similar to how Saint-Germain and her friends risked their lives to save the others. With humanity working together to hold back Shem-Ha's hacking attempt, the wielders activate their X-Drive in preparation for their final battle against Shem-Ha.
