A squid-like creature, known as a Happian, leaves his home planet with the desire to spread happiness across the universe. He lands on Earth, but quickly finds himself in danger of captivity by its inhabitants. Fortunately, he is found by an unsmiling little girl named Shizuka Kuze, who feeds him and names him Takopii. Feeling indebted, Takopii decides to do everything in his power to bring a smile to her face. The task is easier said than done, however. Shizuka is bullied by her classmates, sh...
An earnest alien’s quest to make a lonely girl smile spirals into a time‑twisted lesson on real happiness.
When a curious alien from the distant planet Happi crash‑lands on Earth, its sole mission is simple: scatter joy wherever it goes. The creature, resembling a translucent squid, is rescued by Shizuka Kuze, a stoic elementary‑schooler whose life is a collage of loneliness, bullying, and an absentee father. Naming the newcomer Takopii, she offers it the first taste of human kindness—a bowl of rice and a place to hide. Grateful and earnest, Takopii vows to become the catalyst for Shizuka’s smile, believing that a single burst of happiness can rewrite her bleak routine. Yet human emotions are far messier than the alien’s textbook definition of joy. As Takopii’s well‑meaning schemes—ranging from elaborate pranks to time‑bending shortcuts—spiral out of control, they expose deeper wounds and unintended side effects. Shizuka’s only steady anchor, her dog Chappy, becomes both a source of comfort and a catalyst for chaos when Takopii’s experiments threaten the fragile balance of their lives. Across six tightly‑paced episodes, the series blends sci‑fi intrigue with raw teenage drama, forcing the alien to confront the limits of its optimism and the true cost of forcing happiness onto a world that isn’t ready for it.
A deceptively cute alien tries to make a miserable girl happy, but the series unflinchingly portrays her horrific home life, brutal bullying, and eventual descent into violence across repeating timelines. The contrast between the adorable art style and the extreme child suffering makes this a uniquely harrowing psychological experience.
