7-A. The first is the second is the third.

This is a world filled with life and advanced technology. A world where there is wildlife and metallic life known as "Mechcas". In this world, humans and animals depend on a heart called a Jinsei Core (人生: Life). Every human has a core like heart that empowers and gives abilities to humans and animals. This also applies to Mechcas, who also have Jinsei Cores. These cores give and grant abilities, with 7 slots of elemental or advanced abilities. Upgradeable Katanas respond well to your core ability and energy. Bows and arrows also respond well to cores, making them the most powerful weapon at range and in combat. Any melee weapon is advanced and naturally technological. They are upgradeable and very efficient.

Mechas are creatures with conscience and mind; but without optional heart. They can empathize and form friendships to exercise and build a pack. There are varieties of Mechcas, such as: The Bushi, who are the most violent and territorial. The Kasa, who are peaceful weavers, but are also very defensive when they survive an enemy. There are also the monks, who are the most sacred on earth. They care for and maintain harmony in each Kingdom and in each country of the world.

Farmers and farmers: These are very important in the terrestrial and natural life of the earth. These Mechcas are in charge of creating fruits and vegetables for wildlife and humans. They take care of nature and are very aggressive when you cut down a tree without needing it. For that you have to talk to them or do jobs for them. Mechca farmers are very kind and gentle with humans and loving with creatures. They can grow to be about 4 or 3 meters tall. They are very robust.

Then there are the predators: these Mechcas are the most aggressive and violent in the land 7-A. They are very envious and dominant. They hate anything they see in their path or that bothers them. They are cruel and like to intimidate the creatures of this world. These predators can reach 2 meters tall, they are very agile and fast.

No mecha can communicate with humans in human language, but they can communicate with them through gestures and hand signals, or simply by displaying holograms above their heads.
