I surrendered to the enemy of Brother Jiangnan!" Sakura Igarashi: "Brother Jiangnan is the strongest and most powerful Kamen Rider!" Brother Diqi: "I was just passing by... Huh? You were passing by too!?" Tokiwa Shogo: "I am not the Demon King, Qin Feng is the real Demon King!" This novel and its characters are purely fictitious.
