Chapter -2 - Important Things - Spoilers*
I am going to use this chapter to clarify some things about characters, places, and other things.
They will be "spoilers" but not the kind that gets in the way of your appreciation of the story. I will not write here more essential things about the plot like mysteries and surprises.
This is just a chapter for you to know good things. But if you don't want spoilers... don't read!
-----------------------------
Sorry for writing and English, which may be worse in this chapter. Sorry also for the paragraphs so big. It is not my intention that this is a pleasant chapter to read and just an informative text.

----------------------------
L.u.s.t's real body - L.u.s.t, like the other great demons, makes contracts using a replica of their real body made of demonic energy. This body that she now uses is separate from her soul and is not her real body. Her real body and that of others are hidden in the demonic kingdom to avoid being caught by a very powerful enemy. The real body of L.u.s.t and the others is v.i.r.g.i.n. They inherited the power of sins shortly after the great enemy killed their predecessors by making the seven hide their bodies and separate their souls to start making contracts with the intention of finding strong hosts to help them.
P. S. - L.u.s.t's real body has horns, tail, fangs, and wings just like a succubus, but she uses a more "human" version not to scare the MC. But the MC will find out when he meets "Pride," and she will change.
The Evil King - The king's real name is Michael. But he gave up anything that could stop him from doing the best for the kingdom. His world is divided into two great powers, and his is the losing side. The "good" side appealed him to "Evil King," and he used this to have an advantage not only scaring the enemies but his own people to make everyone follow his orders and thus have a better chance of surviving. Despite the good side of having great advantages, they could not fight without suffering big losses. Like the Evil King, they plan something complex to win.
Why not stay in the MC main world - The Evil King, through an ancient ritual, contacted the seven great demons and together plotted their strategy to win the great war that would come. The demons taught the King how to improve his children's natural talents since birth to make them very strong and thus be good hosts for them in exchange for help in the war. But the great demons need time and a place to do things related to their sins (a mess), so it wouldn't be appropriate to use that world for these "experiments." When the demons communicated with the King, they felt the presence of an ancient super-powerful creature in that world. This being warned that they should follow their plans elsewhere and they must only return there after ten years when the war is supposed to have almost started. Why? It will be part of the main plot so I can't tell you much.
Argerim World - The first world where the MC goes. The seven great demons chose three worlds where the dangers were less to do their thing with the hosts and get stronger. Argerim is the most dangerous and largest of the three worlds, while the other two are moons of it. Two sisters/sins were sent to each moon and two (not Sophia) to Argerim with the MC. Each great demon has its own personality and strategy to strengthen itself, so they could not be very friendly with each other even if they are on the same side. Everything is possible.
