Anime Villain Summoning System

Building your own kingdom! Waging wars against different kingdoms and empires! What would you do if you have the ability to summon characters from anime? However, it wasn't the good guys, but the bad guys, the antagonist, the villains! This is a story with no sense and filled with overpowered characters! Basically, it is a boring story! If you have nothing to read, waste several minutes of your life here.
