Mobile Suit Gundam SEED (2002)

S1E22 The Sea Dyed Red

The Archangel sails across the Red Sea, bound for the neutral Orb Union, with Cagalli and Ledonir Kisaka aboard. Still shaken by the last battle, Kira opens up to Cagalli about why he continues to fight, a conversation that stirs jealousy in Flay. Suddenly, ZAFT forces strike with aerial and underwater mobile suits. Kira and Mu launch a counterattack and succeed in destroying the attackers.
