(Giant mecha + monster + Cthulhu + Notre Dame + Warhammer-like setting) 20 years ago, those monsters from the deep sea set foot on human land. The empire paid the price of 60 giant cannons, four base cities were destroyed, 4 million people were killed, and 3 million people turned into madmen. However, just as humans were arguing over whether to resist or escape, the gaze from the abyss fell again a month later.
Human beings must resist, for themselves, for their homeland, and for civilization. To truly confront monsters, human beings need to create their own monsters.
