Can this class loser turn his life around back home...?"-- A Knight in Shining Thunderbolt Armor !After stopping an assassination attempt on King Arnold and Princess Lexia, Yuuya is roped into the hunt for the traitorous Prince Reigar. In the ensuing chaos, a mysterious girl attacks without warning. Her goal? Destroy the world! To have any chance of holding his own against this new foe who is on par with Master Rabbit, Yuuya will have to think fast—as fast as lightning.
