Doraemon and Tatsumaki

This fanfiction seamlessly blends the S-Class hero Tornado of Terror from One-Punch Man with the heartwarming everyday life of Doraemon.

The story begins with a carefully planned deception: Tornado moves in with the Nobi family under the guise of an exchange student. To prevent the destruction of Earth, Doraemon uses a “Black Ribbon” to seal away her psychic powers completely, forcibly reducing her physical abilities to those of an ordinary fifth-grade girl. The once-mighty S-Class hero can no longer run fast or open a bottle, and even gets fish bones stuck in her throat.

Forced to begin a life of “training” at the Nobi household, the fallen Tornado must contend with the absolute authority of “Finance Minister” Tamako Nobi. She also has to endure the humiliation of scoring zero on a math test and repay the enormous debt she ran up through her selfishness by doing chores and mopping floors. Yet amid these hilarious daily “trials,” the good-for-nothing Nobita becomes her only “safe harbor,” Bang offers the kindness of a doting grandpa, and the Nobi family gives her a sense of belonging she has never known.

This is more than a story about losing one's powers. It's a heartwarming journey in which an arrogant goddess, surrounded by ordinary people, relearns how to be a “little human girl” and eventually comes to understand love and responsibility.
