About “Kouchu Ouja MushiKing”
“Kouchu Ouja MushiKing” is an intellectual property that originated from an arcade game where players collect and raise real-life insects like rhinoceros beetles and stag beetles to battle using cards. The game is characterized by its educational elements, similar to an insect encyclopedia, and its simple rock-paper-scissors style battles.
