The second season of Hello Cocomong.

Eight hundred years ago, terrifying demons threatened mankind's existence. On the brink of extinction, humans prayed to their gods, calling out for someone to save them. Emerging from these desperate pleas for salvation, battle deities known as the Idaten were born. Possessing unnatural strength and endurance, the Idaten managed to defeat the demons and an era of unprecedented peace was finally ushered in. Having never encountered demons before, the present generation of Idaten knows nothing of the demon's brutality, but they have instead only lived a peaceful existence. Training under Rin, the only remaining Idaten from 800 years ago, the new Idaten find ways to survive in a time where they have seemingly outlived their usefulness. However, when the tyrannical Zoble Empire resurrects a demon, the misfit crop of gods are called to the battlefield against their natural enemy once more.

I can dance! I can sing! So, I can speak English! Hello Cocomong is a series of musical episodes teaching kids through song and dance. A large amount of episodes are aimed to teach English to Korean speaking children, though the intention is lost with the official English dub of the show.

The Taira clan, also known as the Heike, holds immense authority over Japan. When a young girl, gifted with an odd eye that allows her to see the future, foolishly disrespects the clan, her father pays the price of her crime with his life. Soon after, as fate would have it, Taira no Shigemori—the eldest son of the clan leader—stumbles upon the same unfortunate girl, who now calls herself Biwa. Biwa informs him that the downfall of the Heike is imminent. After learning of the great injustice Biwa suffered at the Heike's hands, Shigemori vows to take her in and care for her rather than let her be killed. In an era of rising military tension, the Heike are in the midst of a cunning struggle for power, and bloodstained war is on the horizon. Shigemori, whose eyes allow him to see spirits of the dead, is both anxious and hopeful to prevent his clan's demise. Biwa, however, is reluctant to reveal the future to him and must adapt to her new life filled with both happiness and sorrow in this pivotal chapter in Japanese history.
