Dai Mugen once held an unmatched passion for playing the drums. However, after being defeated by rival drummer Rin Tanba in a competition, he is left questioning where his heart lies and quits as a result. One day, Dai has a fateful encounter with a strange creature named Goutetsu, a self-proclaimed god. Spotting the boy's hidden potential, Goutetsu quickly appoints Dai as his oyakata—a coach who can guide Goutetsu in the world of kamizumo, the battles between gods through sumo wrestling. Within kamizumo matches, the gods are powered through the drumbeats struck by their oyakata, which forces Dai to pick up the mallets once more. As the duo slowly racks up victories, Dai confronts his self-doubts and reignites his passion in the new endeavor to stand on kamizumo's topmost stage.

A long time ago, Zeus, the great god, created a three–tier hierarchy of angels, top, middle and lower, although they were supposed to be equal. Also, Zeus appointed 6 angels as Saint Beasts who govern the animals of Earth. They were: Go, the seiyu; Shin, the genbu; Rei, the suzaku; Guy, the byakko; Yuda, the kirin; and Ruka, the hooh. However, Kira, the shooting star, and Maya, the fuga, didn’t attend the selection tests and left for the Earth. The six angels fulfilled their tasks faithfully. However, because of Zeus’s increasingly tyrannical acts, they begin to mistrust him. (Source: AnimeNfo)

Long ago there was a war in Heaven which resulted in Judas and Luca – two of the six specially-chosen, talented and strong Saint Beasts – being cast out and imprisoned in Hell for leading the rebellion. But before that Heaven had been a peaceful place where the angels happily lived their lives. In this time, Judas, Luca, Goh, Shin, Rey and Gai are adolescent angels in Heaven who, on the day of Benediction, are made into adults by the supreme god Zeus. With each of the six having their own special abilities and new adult bodies to get used to, opportunities to meet each other arise and new friendships are formed. (Source: Anivide)
