Shadowblade777, sometimes known as Darkboy132 is a member of the Four Heavenly Editors and sits right next to Tamamo.
Like Tamamo, he is a master of earth-based magic, and can use the earth's weight to deliver crushing blows. However, like Granberia, this doesn't stop him from using other elemental skills.
Like Tamamo, he can be playful but not malicious. Still, he should not be underestimated.
As a member of the Four Heavenly Editors, he is responsible for filling information plotted out by the Editing Lord as well as the other Heavenly Editors.
