As the Eligos Peerage’s month of special training neared its end, its members showed major growth, including Rem’s increasing control over her Oni Transformation. Leo spoke with Rias about Ravel joining his peerage and learned how Rias had recruited Issei Hyoudou, leaving him shocked that Sona Shitori’s discipline had curbed Issei’s lecherous behavior.

• Yukino Yukinoshita, Asuna Yuuki, Utaha Kasumigaoka, Mahiru Shiina, Ravel, Ram, and Rem made progress during the training, and Rem learned to control her Oni Transformation for two minutes.

• Leo was stunned to hear that Issei had changed his behavior.

• Rias agreed to stay alert, unaware that another powerful enemy would reach Kuoh Town before the White Dragon Emperor attacked.
• After a month of special training in the Underworld, Leo announced that the Eligos Peerage had finished its final session and told the girls to clean up before returning.

• Ram, Rem, and Ravel were shaken by Leo’s Zenith Tempest, while Yukino Yukinoshita and the others noticed that it now changed the climate throughout the entire space.

• As Leo launched a combined lightning-and-fire attack, Miyamoto Musashi raised the Statue of Nio and used One Blade Three Bows to cut through everything.

Miyamoto Musashi unleashed a slash that threatened to shatter the basement space, forcing Leo to awaken his Balance Breaker and contain the distortion. After Ravel used Tears of the Phoenix to heal the badly injured Musashi, she woke up to find everyone scolding her for nearly getting them killed.

• Miyamoto Musashi's full-force sword strike began splitting the basement space and threatened to banish everyone into the Dimensional Gap.
