The Furious League

Where Zythern is a young high-spirited boy (age 19) born on planet Artehrea as a Fallen Artemis (a guardian angel, in better meaning) and part of another species, who has a great passion for aerial racing and dreams of becoming a Furious Angel, the starkest angels in the sky without fear, noteworthy of being experts in flying and races, and also being their duty to protect civilians.
Although using speed to his advantage and showing off his aerial aerobatic tricks, Zythern actually has little skills. He asks his long-time friend Soundwave for help, who is a member of Furious Angels himself, to show him and train him what it is like to truly be a experienced flier.
