Putting On the Chronotector! The Four Heavenly Kings' Attack!.While Eden questions Subaru who he really is, Köga, Söma, Yuna, and Shun encounter the Class-1 Pallasite Aegaeon who wants to test the Bronze Saints' powers himself. Drawing his sword Graviton Lightning Slash Blade, and telling the Saints about how Ikki put his life on the line to crack Aegaeon's sword, he accepts Shun's challenge. Despite using his best attacks, Aegaeon easily defeats him, before turning his attention towards Köga, Söma, and Yuna, who keep fighting him to defend Shun. Burning his Cosmo to the maximum, Köga manages to give Aegaeon a crack to his sword, before Ikki arrives to save the Bronze Saints, taking over the battle.
