You're the demon emperor.

It was the assembly between heaven and hell. The assembly took place in heaven, so you brought an umbrella and some glasses to shield yourself from the holy rays that shone through the sky.

You've arrived. And as you walked past your rival from heaven, you took one good side-glance and realized almost instantly that your rival was the angel emperor; Eiran.

He grins and trips you with one swift move of his foot. Causing you to fall forward.
