Long ago, a war erupted in Heaven, resulting in Judas and Luca—two of the six specially chosen, talented, and powerful Saint Beasts—being cast out and imprisoned in Hell for instigating the rebellion. However, before that conflict, Heaven was a tranquil realm where angels lived happily. During this earlier period, Judas, Luca, Goh, Shin, Rey, and Gai were adolescent angels in Heaven. On the day of Benediction, the supreme god Zeus transformed them into adults. Each of the six possessed unique abilities and had to adjust to their new adult bodies. These changes led to opportunities for them to meet one another, and new friendships began to form.
