The Avent (S01E10)

Aldebaran bears Kagaho’s powerful attack, and defeats him with the “Titan’s Nova,” a move so powerful it breaks the earth. However, Aldebaran feels Kagaho is not a threat, and does not finish him off. The hurt Kagaho flies away into the twilight sky. Later at the Sanctuary, Athena’s protective spell is violently torn by a giant cosmos. Lord Hades appears before Sasha! (Crunchyroll)
