I'm the Evil Lord of an Intergalactic Empire! (Light Novel) Vol. 7

LIAM THE HERO?! After repelling the United Kingdom's invasion, Liam's faction is now more powerful than the First Prince's. Before he can settle things with Calvin, though, a magic circle pops up out of nowhere right at Liam's feet. He and Japanese high school girl Kanami have both been caught up in an undeveloped planet's hero summoning and are tasked with nothing less than defeating the Demon Lord! But...Liam's supposed to be evil, so why is he fighting some Demon Lord as a hero?!
