Godzilla 怪獣惑星

From the introduction:

At the turn of the 21st century, humanity underwent a crisis unlike any that had ever even been conceived before then. The seemingly spontaneous arrival of Kamacuras in Manhattan and the subsequent destruction it causes will be the herald of a new and bleak era for humanity. The trend of new, horrific monster species appearing and wreaking havoc upon humanity would be a continuous one. The monsters seemed endless until the year 2030. On May 29th 2030, the beginning of humanities end was heralded. The eviscerated corpse of a Kamoebas would be found upon the shores of Odo Island, along with the whispers of a horrific name: Godzilla.
