Shu continues his fight with Rudolph. After taking a blow from Blue Dragon, Rudolph assumes his dragon form. Rudolph and the Shu/Blue Dragon are easily matched until Rudolph manages to strangle him. He repels Noi and the Bouquet/Saber Tiger. When Rudolph starts to finish off the Shu/Blue Dragon, Noi unleashes his power which enables his dragon form to get bigger. With this occurrence, Noi engages Rudolph. Both of them are easily matched. Right when Rudolph was about to finish off Noi, he is hit by an attack launched by the Shu/Blue Dragon. Rudolph enters a portal that he created and the Shu/Blue Dragon follows him into it. The Shu/Blue Dragon follows Rudolph into an area where he uses a war machine to defeat the Shu/Blue Dragon. The Investiture Beings' castle is starting to change shape into a large dragon-like war machine. Kluke uses her forcefield ability to protect them from its attack. Just then, Rosekstan's forces arrive as Shu's unconscious body is approached by Primella.
