The Aegis Wielder vs Union Academy

(Wielder of Aegis Male Reader X Crossover)

Y/N is the wielder of a blade named Aegis. Unfortunately, Union Academy found out and decided to chase after him and get him to (forcefully) join them. As he is on the run along with Pyra and Mythra, they were saved by Gwendolyn Stacy/Gwenom and Tsukasa Kadoya/Kamen Rider Decade, who bring them to their base and tells them that Union is trying to bring back Malos and their past enemies. Now Y/N must fight to save the world, and eventually put an end to Union's corruption.
