Meanwhile, Shu Yulin's partner, Oryumon, is also present, reuniting former friends turned adversaries. Digi Police officers arrive to prevent the Sons of Chaos from cracking the Gateway, but the Gatekeepers attack both sides, targeting Digimon tainted by real-world data.
Battle on Multiple Fronts [1:57]
Satsuki, piloting a mechanon, faces A and Lugon. Marvin intervenes, creating chaos and separating the Digi Police. Tartaros aims to fight Yulin while other Sons of Chaos members keep the remaining Digi Police occupied. Lugon evolves into L Lugon and attacks a Commandramon unit, but two mind-linked Commandramon evolve into High Commandramon, deflecting Lugon's attacks.
S Lugon's Arrival [3:40]
AG and Lugon are determined to help their friends. Lugon evolves into S Lugon, a perfect-level dark beast Digimon wielding Vanag Gander. S Lugon defeats the High Commandramon, while Yulin observes. Kosuke reveals to Yulin that she is part of his plan, as he now has three prototype Digimon with different data types. Kosuke's goal is to save Saia, contrasting with Yulin's actions.
Cracking the Gate [5:56]
With a third of her forces lost and Yulin defeated, Satsuki orders a retreat. Kosuke's Digimon, Doron, explains their plan to crack the Gate using old-fashioned interfaces. The requirements are met with three prototype Digimon capable of evolving to the perfect level. They position themselves in a triangle formation, with Kosuke at the center.

As the gate cracking reaches 66%, Lugon senses Omegamon's return. Satsuki stays to save Yulin, defying orders. A Brigade Dramon appears, attacking the Chaos Dramon.

The Source Domain [8:34]
Kosuke, AG, and the prototype Digimon vanish into the Source Domain, a space beyond the index of domains. The Sacred Chalice, an ancient temple, lies within. Spheres of data merge into one, and stone blocks rise to form a circular temple. Everything goes dark, and Professor Renji appears as a projection.

Fenry Lugon's Emergence [11:45]
AG is furious, and Lugon bursts free of restraints, evolving into Fenry Lugon. Kosuke administers medicine to Palmon, freeing himself from Saia's memory.

The Ultimate War Blade [14:16]
