You Can't Come, Sir!

Guster Smith has dedicated 17 years of his life to being a hero - only to remain a penniless nobody in the grand scheme. So when the esteemed archmage, Lord Angel Romero, offers him a mission to once again save the world, he accepts without hesitation. But all is not as it seems, and Guster is about to find about that the archmage has quite the “staff” he uses to work his magic…and a plethora of special techniques bound to blow the knight's mind.
