Apparently my house is in a pretty crazy spot.
About
This is a world where one can travel between the past and the future. However, movement is restricted to specific eras where "Gates of Time" exist. In the past, dragons and ogres coexisted; in the future, humans lived. The two sides interacted through massive gates, but a certain incident caused the past and the future to merge into a single era. Due to differences in culture and values, the Human race and the Dragon-Ogre race came into conflict, splitting into two factions. The Human side established a Dragon-Ogre Extermination Squad led by a suspicious figure at the top, while the Dragon-Ogre side formed the Four Heavenly Kings, consisting of two dragons and two ogres. On the boundary line between the two factions, there is a rule: "Members of opposing factions must never meet." Living right on that boundary line is Guest, who stays there simply because they have neither the money nor the help to move. Eventually, Guest becomes involved with the leaders of both camps—.

Character Circumstances Summary
A detailed summary of the pasts and incidents involving characters from my plot!
Intro
You must not cross that line.
A nation where only humans live, and a nation where dragons and ogres coexist.
Two worlds that once interacted across eras are now completely divided.
The human side claims it is to protect people from dragons and ogres. The dragon and ogre side claims it is to protect their country from humans.
Both sides have maintained this stance, fighting for a long time. And what separates the two nations is—
Not a giant castle wall, nor a deep valley. Only a single white line drawn on the ground.
If you step even a few centimeters across that white line, you are considered an invader of the enemy nation and become their slave. If you are a dragon or an ogre, you are utilized as materials for human weapons and treated however they please.
That is the absolute rule of this world.
Right next to that white line.
In a place that belongs to neither the human nation nor the dragon and ogre nation, a single small house stood.
The one living there is—Guest.
There was no money to move, and no one to help. So, out of necessity, they live in one of the most dangerous places in the world.
The white line is right in front of the house.
Across the line is the nation of those with non-human forms. And on this side of the line is the human nation.
Walk just a few steps, and you enter another country. That is exactly why—trouble breaks out almost every day.
