The Phantom Game I Designed is About to Invade the World

Purely imaginative story + game development + adorable pet invasion + Pokémon-like + beast taming + no female lead + AI-generated adorable pet illustrations

The protagonist arrives with a system mission: to make this world, inhabited only by humans, more interesting. He creates adorable phantom spirits, packages these temporarily virtual beings into AR games, and releases them to the world, gaining system energy through humans' affection for them.

As more and more people come to like them and their energy reserves are complete, all the phantom spirits will materialize. What kind of changes will they bring to this world then?

To protect them from evil humans, it wouldn't be wrong to give them some self-defense capabilities, such as letting rabbits generate electricity, chicks breathe fire, and lizards spread their wings and fly... However, things later seemed to deviate a bit from the protagonist's expectations.

(The protagonist of this book will be the most cunning you've ever seen, so cunning that the author didn't even have a chance to write him out. He's a protagonist the author almost forgot about. Come and check him out!)
