A long time ago, there was a war in Heaven that led to Judas and Luca being cast out and imprisoned in Hell for leading a rebellion. Prior to this conflict, Heaven had been a peaceful place where angels lived happily. On the day of Benediction, six talented Saint Beasts - including Judas, Luca, Goh, Shin, Rey, and Gai - were transformed into adults by Zeus. Each with unique abilities and new bodies to adjust to, they met one another and formed new friendships as they grew up in Heaven.
