With Yuna, Souma, and Ryuhou leaving ahead to the Sanctuary, Koga and Subaru look for Haruto in Japan and find, much to their surprise, that he is now a singer in a rock band. Haruto rejects Koga's pleas to return, claiming that to him, his music is now more important than being a Saint. However, during a concert, Haruto watches Koga and Subaru being attacked by some Pallasites, and to protect his friends and his fans, he dons his brand new Wolf Cloth to join the battle.

Ryuhou, Souma, and Yuna arrive to a village whose survivors of the Pallasite Halimede's attack are under Shun's protection. Among them is Ray, a child whose brother was also frozen by Halimede and blames Shun for it. Halimede instructs Ray to steal the Andromeda Cloth Stone from Shun with the promise of having his brother return to normal, but when the enemy intends to kill both, Shun brings the power of his cloth to the next level.

Aegir fails to defeat Genbu by himself and the Primary Pallasite Hyperion lends his own sword to assist him. Overwhelmed by the massive Cosmo flowing from the sword, the Gold Saint decides to forfeit his own life in an attempt to destroy it.

Once the saints infiltrate the city, Seiya draws the attention of the enemy allowing Koga and the others to push forward. However, Tarvos appears to challenge Koga to a decisive battle and Ryuhou stays behind to assist him.

Koga's party departs to the palace through the secret passage shown by Celeris. However, worried about him, Subaru returns to assist the Equuleus Saint, and can do little to stop him from sacrificing himself to defeat Hati. Before passing away, Celeris entrusts the damaged Equuleus Clothstone to Subaru, and upon rejoining his fellow Bronze Saints, Subaru unlocks its true power to protect them, becoming a Bronze Saint as well.
