📖 Plot Summary

Takopi is a small Happian alien from the planet Happy, who crash-lands on Earth and meets Shizuka, a deeply troubled 9-year-old girl suffering from school bullying and neglect. Believing he can cheer her up, he uses his Happy Gadgets—but when they cause more harm than good, he rewinds time using a time-travel tool to fix the mess.

As Shizuka spirals and tries to end her life, Takopi learns a painful truth: empathy and listening matter more than gadgets. In a tragic and reflective conclusion, Takopi sacrifices himself to reset the timeline—allowing Shizuka and other children to build real healing and friendship, free of technological interference.
