[Anime]Cencoroll

In Cencoroll, large, mostly white amorphous creatures have been appearing in a town modeled after Sapporo, Hokkaido, Japan. Tetsu (Hiro Shimono) is a male high school student who keeps one such shapeshifting creature named Cenco, which he can control via telepathy, though wants to keep it a secret. An inquisitive girl named Yuki (Kana Hanazawa) chances upon Cenco at school when it is transformed into a bicycle. After Tetsu arrives to retrieve the bicycle, Yuki inadvertently causes Cenco to transform back into its normally large form by poking it in the eye. Yuki is much more interested in Cenco than Tetsu and accompanies them into town. There, a boy named Shu (Ryohei Kimura), who controls two of the creatures, confronts Tetsu in order to obtain Cenco. Tetsu manages to fend off Shu's attacks while also protecting Yuki, and they leave while Shu's creature is incapacitated. Shu confronts Yuki later that day and gets her to tell Tetsu to meet and fight Shu again.

The following day, Shu takes Yuki hostage to force Tetsu to come, and places her on a ledge of a tall building. After Tetsu arrives, Shu attacks from afar and manages to cut off one of Cenco's arms. To repair the arm, Cenco removes one of Tetsu's arms, which incapacitates him momentarily. Shu arrives with a much larger creature and Cenco takes Yuki within its body where Tetsu already is. Yuki gets Cenco to change control of it from Tetsu to herself, and after Shu's larger creature eats Cenco along with Yuki, she manages to take control of the larger creature as well. They are subsequently attacked by the military with tanks and missiles, but are protected for the time being when Tetsu changes the creature's shape to that of a massive walnut. Tetsu and Yuki are separated and Shu attempts to take control back from Yuki, but he cannot control the creature anymore and severs the link, effectively killing it. Tetsu makes it back with Cenco to where Yuki and Shu are, and Yuki knocks Shu out with Cenco transformed into a baseball bat. Afterwards, Yuki transforms Cenco into Tetsu's lost arm, which gives him back control of his limb. Shu is later shown having been rescued by his other creature.
