Plantation

A Plantation (プランテーション) is a mobile fortress-city the remnants of humanity reside in following the emergence of the Klaxosaurs. There are at least 200 plantations worldwide.

Appearance
A plantation is oval shaped, and is very large and wide by no more than a mile. All plantations are constructed with steel exteriors and the interior is where the city for the adults resides. In the upper center resides the ‘Birdcage’, the bygone environment where the children (parasites, as they are referred to as) live. All plantations maintain heavy arsenals of weapons, such as cannon bullets and machine guns, to use as defense weapons. Plantations are capable of moving for relocation in mobile mode.

Overview
The project for the construction of the Plantations was first proposed when the planet began decaying due to extensive magma energy drilling, though APE asserted to the public is was due to the frequent attacks from the Klaxosaurs. All the national governments poured their resources to build the plantations and humanity hastily abandoned the surface to move into the plantations. According to Dr. FRANXX, humanity became so tedium with their newfound peace that they not only forgot about the existence of the klaxosaurs but lost all sense in trivial matters, such as emotion, taste, and smell. Zero Two refers to the city as isolated and ‘a one-way street to nowhere’.

Despite the plantations being heavily equipped for direct conflicts, they are still vulnerable to attacks. Hence, the parasites are tasked with residing in the Birdcage to be on standby in case it comes under attack. The upper and lower parts are connected through an elevator that only the parasites and their adult supervisors are allowed to use.

During the siege of Gran Crevasse, Plantation 26 falls victim to a Lehmann-Super Klaxosaur and APE orders the self-destruction of several more. Plantation 13 is destroyed by a giant, colossal klaxosaur hand that appears from inside the Gran Crevasse but only the Birdcage remains intact. As a result, all the surviving parasites are sent to the Bird Nest. Over the next several years, as the parasites begin reconstructing the planet, parts of the plantations are used to build new necessities, such as windmills, houses, and transportation units.

Birdcage
The Birdcage is the bygone environment where the parasites reside at the top center of the plantation. It is much smaller in size compared the plantation and is protected by a glass shield. It consists of vast woods, a few lakes, and a boarding house. All weather elements, such as rain and snow, is controlled by a sprinkler fitting system.

Inner City
The inner city is the core of the plantation and where the adults reside. The city illuminates in a golden aura and is presented as luxurious and divine. The adults rarely venture through the city and are segregated from the children. The city oparates through magma energy power plants.
