Athena enters Sisyphos's dream. There she finds that Sisyphos torn by guilt over taking her away from Alone and Tenma. He thinks he ruined her life, and caused the Holy War. Athena risks her life to attempt to persuade him to open his heart and rise from darkness. With Sisyphos awakened back at the Sanctuary, he shoots an arrow blessed by Athena toward Oneiros. El Cid uses his Excalibur to break the arrow into four pieces, piercing the souls of the four Dream Gods simultaneously. In a last-ditch effort, Oneiros charges toward Tenma so that he too would perish in the imminent explosion of his soul. El Cid fends off Oneiros by lifting himself and the dream god into the sky, sacrificing himself to protect Tenma as Oneiros explodes.
