Kouga defeats one of the Heavenly Kings in one hit before he manages to once again keep his Darkness Cosmo due to him having reached his Seventh Sense earlier and Yuna calling out to him. Sending him ahead, Yuna engages Amor while Souma, Ryuuhou and Haruto engage the remaining three Heavenly Kings, using the last bit of strength they have left in order to finally defeat them. Leaving the rest to Kouga, they collapse to exhaustion. Amor decides to fight Yuna, but is interrupted by Eden who has arrived as well. Following a short fight, Yuna asks Eden to go onward and ...

With the Gold Saints protecting Athena and the Silver Saints looking for clues about the new enemies, Koga is instructed by Seiya and Saori to assemble the other Bronze Saints. Followed by Subaru, Koga encounters with Souma at the Palaestra, where he is working as a substitute teacher. However, when the Tertiary Pallasite Loge, a master of spear combat appears at the Palaestra, Koga, Souma, and Subaru must work together to protect the students.

As the battle intensifies, Souma and Subaru fall back to assist the other Steel Saints in time to rescue only two of them, Kerry and Emma. Soon after, they are attacked by Loge and forced to retreat once Souma is injured. Surrounded by the enemy forces, Souma and the Steel Saints must work together to break Loge's siege and fight back.
