The Godly Game: I Can Summon Monsters from Across Anime

(No harem, no formulaic tropes, no invincibility, no System, no brainless decisions, no wish fulfillment, no behind-the-scenes scheming. Read at your own discretion.) The moment the mask is put on, the game of the gods begins. On another world's continent, characters from all kinds of anime appear one after another: magical girls, white-haired corpse kings, Attack on Titan, vampires, dragons, mecha, monsters, pirates, Soul Reapers... We fight one another. We evolve together. We descend into hell. We storm the divine throne. This is a battle between humans and monsters, as well as a battle between humans. The victors become gods, and the defeated leave the stage. This book is also known as "You Were Supposed to Be the Villain, So Why Are You Dating a Magical Girl?"
