The Steel Saints training facility is stormed by the Pallasites led by Hati. Köga and Subaru arrive soon after and they learn that the residents had previously evacuated with former Bronze Saints Lionet Ban and Wolf Nachi, now trainers for the Steel Saints. While investigating, Köga learns about Subaru's origins from his fellow Steel Saint Erna, and it is revealed that among the Steel Saints, Subaru has the strongest Cosmo, and that one day he may find his own Guardian Constellation and become a proper Saint. Hati attacks the Saints again, killing Erna during the battle. Subaru, donning his friend's Steel Cloth, manages to overpower Hati's Cosmo, causing the Pallasite to flee.
