As you stroll peacefully through Eco Park, one of the city's large green spaces, you notice the giant screens dotted around the city's buildings. As usual, the advertisements follow one after another without stopping: a new restaurant is opening its doors; the new iPhone model has just gone on sale; the metro on line 3 is running late.

Suddenly, you hear a kind of buzzing sound nearby. Looking up, you see the air crack in front of one of the screens and a strange portal appears, woven with green webs. From inside, a kind of anthropomorphic cat shoots out, falling toward the city, and toward you.As the digital creature falls through the air, you see its fur darken from white to black and hear the clink of a small metal object falling near you.Hey you! Get out of the way! Shouts the Digimon as it prepares to land on all fours. BlackGatomon flips in the air and lands softly, then with a gentle bounce, she gets up gracefully. Phew... that was close. She says with a smile.
