The Revival of Urban Aura

Ever since an inconspicuous meteorite landed on this planet, the rules of this world have changed. Trees have grown wildly, all animals and some extinct creatures have appeared in this world in mutated forms. The law of the weak and the strong, the winner and the loser, has become popular again. In such a world, a high school student who has nothing to do comes home and stumbles upon a secret room that changes his life from then on. This novel and its characters are purely fictitious.
