Jurassic: Start by Becoming a Mouse
After twenty years of living an ordinary life in the world he transmigrated into, Milo is certain that nothing in his life will ever change.
His days consist of nothing more than working, going home, and having dinner with his sister and brother-in-law.
But everything collapses one morning. He wakes to find his entire neighborhood transformed into a wild expanse of overgrown greenery.
The power is out, the water no longer runs, and the world suddenly feels foreign—as if it’s no longer the place he once knew.
There are no sirens, no warnings, no news. Instead, strange phenomena unfold: plants turn hostile, animals grow vicious, and massive monsters—whose skeletons he had only ever seen in museums—begin appearing like mushrooms after the rain.
Then every slain creature releases a floating card, and that card, when touched, grants abilities no human could ever imagine.
Milo is the first to experience it. Upon touching the “Rat” card, his body transforms into a half-human, half-animal form—fast, agile, with a sense of smell far too sharp to be considered normal.
But the real danger isn’t the card itself… It's the fact that humans also drop cards when they die.
With his unique ability, “Fusion,” Milo can combine cards, weapons, and even everyday objects into far more powerful tools and armaments.
Yet that very power makes him a target. In a lawless world, neighbors can turn into enemies, and any encounter can end in murder over a single rare card.
And the stronger his ability becomes, the clearer one truth emerges—this disaster is no coincidence. It is merely the beginning… of something far greater.
