Plot summary
The plot of the series revolves around Nnu-Anu-Kf, a good-hearted alien from the Happy Planet, who looks like an octopus and comes to Earth on a mission to spread happiness. After a plane crash and a run-in with the police, he meets Shizuka, a girl of only 9 years who is being bullied by her classmate Marina all the time.
Shizuka finds solace in her dog Chappy and decides to call the alien Takopi because he looks like an octopus. In an effort to make things right, Takopi uses the Happy Gadgets of his planet to help Shizuka's situation. However, when Marina plays a trick by having Chappy picked up by animal control, things go so wrong that Takopi cannot grasp them.
By mistake, Shizuka, through one of Takopi's gadgets, has a detrimental effect on the alien. Having to deal with that, Takopi discovers that being human is more than just emotions; it also comes with consequences sometimes. After he realises the error he has made, Takopi travels back in time to change the timeline and genuinely help Shizuka.
What to expect from Takopi's Original Sin episode 1 (Speculative)

Takopi's Original Sin episode 1 will probably focus on the main character's relationships and bring in Takopi, Shizuka, and Marina together with their respective family backgrounds and personal situations.
As an alien who does not know anything about human emotions and social complexities, Takopi's first absorption will be that of his unattained, pure innocence of the harsh realities of Earth. The episode may show Shizuka's everyday fight with bullying and the friendship with Chappy being established, which will be the basis for the emotional conflict driving the series.
