Hidden City

**The Hidden City** is a city populated by Yōkai and is located in the depths of New York.

## Description

The Hidden City is located somewhere far beneath New York state seemingly within a vast subterranean cavity. While it is currently unknown just how deep in the Earth the Hidden City is, it is below the sewers of New York City ("Anatawa Hitorijanai"). It is a secret city, home to the Yōkai species. Although the vast majority of Yōkai reside within the Hidden City, some live on the surface disguised among humans. Just as some of the Yōkai are, the Hidden City is mystic in nature. Examples of the Hidden City's mystic properties are that teleportation via portals is common enough where a portal-specific phenomenon is termed "portal jacking" and is well-known among Hidden City citizens, city objects levitate (e.g., pirate ships), curses can be inflicted upon one's finances ("Insane in the Mama Train"), among *numerous* other mystic instances that are shown. In contrast to the industrial aesthetic of New York City in the series, the Hidden City's architecture is highly naturalistic. Organic features are prolific in its infrastructure such as skeletons of various sizes and faces and heads, both human-like and animal-like, protruding from ceilings and walls. The buildings, especially residential buildings, of the Hidden City often have curved roofs. The Hidden City is governed by the Council of Heads and it is policed by the Hidden City Police. Mystic taxes are present in the Hidden City as revealed in "Insane in the Mama Train".

## History

The Hidden City became the main residence of the Yōkai once they were driven from the surface by humans and it became their secret society away from humans. However, the means in which and when the humans pushed the Yokai below ground and their motivation to do so is currently unknown.

The Hidden City debuted in "Mystic Mayhem". Guardsmen Garm and Freki opened a portal to the Hidden City in a New York construction site after securing Mayhem and his vial of Empyrean and April O'Neil teleported with them to rescue Mayhem. The Turtles stole a mystic device from Splinter that allowed them to reopen the portal Garm and Freki and traveled through it, teleporting themselves into the Hidden City. They landed right in front of Baron Draxum's laboratory and were greeted by April and afterwards they all ventured inside. After battling Draxum and his minions, Huginn and Muninn, and saving Mayhem, April and the Turtles used the mystic device to create a portal out of the Hidden City into New York to escape the large explosion they created in the laboratory.
