Looks like you got me!
I knew my fatheaded big bro struck gold when he returned from that Flower Land of his!
By adapting the tales of his journeys into a series of video games of our own, we could finally take our rightful place as kings of video games from those loathsome brothers!
But that accursed place changed him. He wasn't himself when he returned, no longer cared about our lifelong rivalry or ruling the world of gaming, so I... I had to get rid of him.
Living a fake life ever since, I shaved my moustache, got those dumb-looking glasses, got a family. I even painted my favourite cap into his disgusting colour to avoid suspicion.
But it's all coming to an end.
I am the owner of the largest independent gaming franchise in the world. And now the stage is finally set to go Official. And when I finally wipe those little fools, who helped me spread my influence worldwide off the soles of my boots, every man, woman, and child will be forced to buy Touhou 20: Mycelial Proctocracy from MY Official digital storefront! And then I will crush the Big Red once and for all!
WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH-HA-HA-HA-HA-HA-HA!
