Mawaru-Penguindrum (2011)

The story centers on the three brothers and sisters of the Takakura family, with Takakura Kanaye (voiced by Kimura Takamura), Takakura Jingma (voiced by Yohei Kimura) and his terminally ill sister Yoshio Takakura (voiced by Arakawa Miyoka). The Takakura brothers, who have a sister-control complex, both cherish Yangyi very much, but the doctor told them to be ready to lose their sister at any time. On that day, the three brothers and sisters went to the aquarium to play together, but in a twinkling of an eye, the two brothers found their sister missing, and then they found the sunken sun lying unawakened in the middle of the crowd. The ineffective rescue was declared dead, and the Yangzheng woke up in the morgue! The surprised brothers took their sister home, and soon they received a strange parcel that unexpectedly found three enigmatic penguins inside. These three penguins are so naive that no one can see them except them. How on earth is all this going on, and how will the gear of fate turn?
