In secret, alien parasites drift downwards toward Earth. Their directive: to take control of a human body and thrive in secret. When a parasite attempts to take over Shinji, an ordinary high school student, he stops it in his arm to save his mind. With the strange power of amorphous muscle, the curious parasite strikes an uneasy truce with Shinji: it will keep him alive and strong so that it may continue living, and will help protect him from the other parasites that might not take kindly to Shinji's mind still actively working. Can Shinji gain the courage to face the parasites and protect humanity? And would it even make a difference if he did?

In the idyllic, suburban Soil New Town, everyone's lives are picturesque, down to the mandatory perfectly-manicured flower bed in front of every house. But this peaceful façade is shattered when the well-known Suzushiro family disappears during a power outage, leaving behind nothing but a pillar of salt. Things get even weirder with the arrival of a mountain of this same salt at the local school, a crossdresser fixated on transmission towers, and threatening messages demanding that every citizen pay a portion of the Suzushiro family’s ransom. The plain and often-frazzled detective Onoda and her sexist and hygienically-challenged boss, Sergeant Yokoi, are called in from out of town to help, but it's a tough case to crack. Will they be able to get any information out of the gossiping townspeople, all of whom hate outsiders and have something to hide?

From the perspective of an alien planet with super-advanced technology and tiny (1/60th the size of a human) inhabitants, planet Earth was the perfect location to banish their worst criminals. Five of said criminals were sent to the planet to be exiled, attached to little critters like frogs and rabbits so they can never be fully active.
