9 lands were formed in Iuyizama Shakenenzenki or known as Iuzenki.
These were the; Widers from the North West, Lau Spring from the East South East, Marill Shacc from the North. Euzenki Kingdom from the Center of Iuzenki, Ubactia from the North East, Millwalls from the South, Cratter Spring from the South East, Nym from the South West, and Blue Stjonur from the West and also know to be the biggest land from Iuyizama Shankenenzenki.
Marill Shacc was the center of Widers and Ubactia from the North. Down Ubactia, the Lau Spring, from its left, it was the Cratter Spring. Millwalls was the center of Nym (left side) and Cratter Spring (left side) from the South. Above Nym from the left side, it was the Blue Stjonur from the West, and at the center of all, where the diamond-shaped kingdom of Euzenki.
Once, Millwalls were attacked by the nitro's, leaving normal people behind it eaten and killed. Millwalls people were called Milles. The city was naïve about the attack of the nitro's and none of them knows where it came from. Milles, with the thought of that, it came outside the land of Iuzenki, as the people from Euzenki kingdom or the Euzenians People of the Warrior Ieuzen, investigate, there were no traces of the monsters outside the land and was known only to have a large body of water surrounding the land.
Continuously, Euzanians people of the warrior Ieuzen investigates the ocean but shocked because the large body of water that was once investigated was now a plain dangerous ground of forest trees. Euzanians people of the warrior Ieuzen together with the people of each city came up to help with the plan, creating a toxic barrier at the end of each city so that nitro's won't be able to attack inside and won't lose any of the citizens.
As people are aware of what happened in Millwalls, they started working on some chemical elements and weapons especially old men and old women practicing building weapons before nitro's once again attack.
For now, Millwalls city was down and is slowly recovering after 7 years of the attack.
Nitro's are still unknown from how they came from, so as some children are battling for their own fight to protect themselves because of the loss of their home and family, some are also training up to protect the people of each city.
3 months, training was stopped, it shocked the whole city as nitro's, without knowing, entered the Lau Spring from the north.
There are two categories of those who fight against nitros's. The trained and those who have their own capabilities to survive. Euzanians doesn't have the ability to adopt children because of what happened to the Millwalls which were one of the growing economic city of the Iuzenki.
The attack from the Millwalls that the nitro's left was the whole city with level 1 nitro's, approximately 10 creatures.This was reported from one of the Euzanians people of the Warrior Iuezen as he stated out of 5,000 Euzanians people of the Warrior Iuezen, only 15 of them survived during the attack.
