Rotary Penguin Tank

The story unfolds around the three brothers and sisters of the Takakura family. The two brothers, Takakura Akima (voiced by Kimura Ryohei), and their terminally ill sister Takakura Yoko (voiced by Arakawa Miho). Both Gao Cang brothers, who have a sister-control complex, cherish their masculinity very much, but the doctor asked them to be prepared to lose their sister at any time. On this day, the three brothers and sisters went to the aquarium to play together, but in a blink of an eye, the two brothers discovered that their sister was missing. Then they found Yang Ming lying on the ground unconscious in the middle of the crowd of onlookers. Yang Ming, who was declared dead after resuscitation failed, woke up in the morgue! The astonished brothers took their sister home. Not long after, they received a strange package. When they opened it, they found three mysterious penguins inside. These three penguins are so naive that no one else can see them except them. What is going on all this, and how will the gears of fate turn?
