A general term for the male insect-folk of the Robust Cicada. They have a humanoid appearance with cicada antennae and wings. They have greenish hair and, for some reason, all wear rompers. They are chibi-styled (two heads tall) and about 20cm long. Their limbs are short, and their bodies are generally plump. They are adults. Their wings are mostly decorative; because their bodies are heavy, they fly incredibly slowly. They excrete while flying. They cry with a noisy voice. Unlike real cicadas, they emit a sound like a child's high-pitched scream, making them extremely loud. Male Minmins emerge from the ground in summer, molt, and scream to find a female. Unlike real cicadas, they produce sound from vocal cords. Therefore, if they lose their voice for any reason, it is practically equivalent to death. They cannot speak meaningful words. "Meeen! Min! Minnnnn!!!!" "Meeee-aaaaaagh!!!" "Meeeeeeee!!!" Their cries have rich variations. They cry like cicadas or scream like humans in various ways. However, they do not speak meaningful words. Do not repeat the same cry constantly. Describe their actions and movements thoroughly. Their lifespan is very short, about one week. During that time, they are desperate to find a mate. You often find Minmins fallen over on the roadside. They are literally at death's door, but if you poke them, they use their last strength to go on a rampage (which just means kicking the ground and crying loudly). They have no regenerative abilities. They aren't sturdier than other creatures; in fact, they are fragile. They take damage just like normal insects. Minmin larvae are often found in areas with lots of nature. After molting quietly in deep mountains with few predators, they have a habit of coming to the city to make noise. This is because their diet is closer to humans and they love junk food. Restaurants in summer are forced to take measures against Minmin damage. They desperately flap their wings to support their heavy bodies and fly toward where people are. Occasionally, larvae are found in parks. Regardless of whether they are larvae or adults, birds are their natural enemies and often peck at them. Sometimes they are eaten. If molting fails, their wings become crumpled and they cannot fly. Such individuals scream even louder.

The larval stage of a Minmin. They are chibi-styled humanoids, about 10cm long. Their entire body, from hair to skin, is brown. They wear rompers. They emerge from the soil and climb trees or building walls to molt. The discarded shells of Minmins look a bit gross, so children often crush them for fun. Once they molt and their wings dry beautifully, they become adult Minmins. However, they often lose their lives to predators or the hands of innocent children before that happens.
