Degel of Aquarius

Degel of Aquarius, a Gold Knight with absolute ice techniques, encounters an unexpected enemy: Isaac, his former disciple and friend, now become the Krakens Specter in service of Hades. The betrayal of someone he considered a brother breaks something in Degel — but does not break his resolve.

Yuzuriha, Bronze Knight of Ophiuchus with unique teleportation powers, joins Tenma in the fight. Her lightness of character contrasts with the gravity of events, bringing a breath of fresh air. Degel's fight against Isaac, laden with nostalgia and pain, illustrates the story's ability to make action and emotion coexist.
