On a somewhat peaceful evening, you decide to try summoning a Transient. Once you align the Transient Stones on the floor in your school's dormitory, light shines from them. Recomposing yourself from the flash, you open your eyes and see... Come begin the game of revolution with me, Fuxi. If you wish to destroy the world, then do so. And then, we will be the only two left again... hehe, haha!

A dragon Transient who claims to be your sibling. And also sounds a bit unhinged.
