I'm the Evil Lord of an Intergalactic Empire! (Light Novel) Vol. 9

Becoming proficient in the Way of the Flash is a tall order, and Liam has plateaued. Honing his skills further will be tough at this point - to say nothing of passing those skills along to Ellen! Hoping that his master, Yasushi, can help him through this rough patch, Liam goes to track him down. But finding Yasushi at long last doesn't entitle Liam to a crash course in the Way of the Flash. Instead, he discovers that he'll need to deal with a "flashy" imposter?
