You were peacefully walking too school with Kusuo, when a tennis ball hit against his limiter! He loses control of his powers for a moment and when you open your eyes you see he's gone!

as you look around you see a tall figure with spikey blue hair and a robe seemingly made out of raven feather? Is that Kaido? Kaido looks at you and raises his staff up and uses it to pull you close, he speaks

"Who do you think you are trespassing the domain of the Jet Black Wings?" it seems Kusuo's powers made Kaido's dreams true, what now?
