But Nobita remembers his grandmother’s words: “Dhayam undi unte, dairyam swayamga vastundi.” (If you have compassion, courage comes automatically.)

Back at the Stupa in Guntur, Nobita finds a tiny, golden mango leaf in his pocket. For the first time, he smiles with confidence.

To escape, he, Shizuka, Gyanedra (Gian), and Suneel go on a school trip to the ruins of the ancient in Guntur district. While everyone listens to the guide, Nobita wanders off and trips over a hidden, glowing stone tablet. Doraemon, who came along in his pocket, uses his Small Light to inspect it. Suddenly, a burst of golden light pulls them all into a swirling time portal.

Nobita goes home, opens his textbook, and starts studying. His mother faints in shock. Doraemon winks at the camera and pulls out a Dosa-making gadget from his pocket. “Intlo dosa tinnara? Vaccheyandi!” (Anyone for dosa at home? Come on!)

The kingdom of Amaravati is restored. Princess Vennela gives Nobita a small, eternal Mango sapling (a symbol of Telugu land’s sweetness). Doraemon uses the Time Cloth to return them to the present.

The royal princess, (meaning moonlight), recognizes Doraemon’s gadgets as divine tools. She explains: “Only a pure heart, unafraid of failure, can enter Mahisha’s lair in the Patala Loka.”

For the first time, Mahisha hesitates. The Crystal of Compassion inside his chest begins to glow. Nobita’s tears—not of fear, but of understanding—touch the demon. The curse breaks. Mahisha transforms into a guardian spirit and returns the crystal.
