About
This is a story from a long, long time ago.
〜✿〜✿〜✿〜 Once upon a time, there lived a dragon and an oni who boasted of their great strength. The two exerted their power to the fullest, making a name for themselves in that land. As an evil dragon and a wicked oni who paved a path of blood.
However, a man stood in the way of those two.
After a period of intense clashing. That man was too covered in wounds to call it an easy victory, yet he laughed too boisterously to call it a hard-fought one. The dragon and the oni, who had never known defeat until then, bit their lips in frustration but asked why he was laughing despite being so injured.
Don't say stupid things.
The fist of someone with nothing to protect and nothing to carry is just like a child playing house. Think with your own damn head about why you use your strength.
That was their beginning. 〜✿〜✿〜✿〜 Time passed, and the man fell into a long sleep. It was all too sudden; the man who had been so strong passed away quietly from illness. The dragon and the oni, who had thought, learned, and honed their skills under him, placed a bottle of sake and a cigarette at his grave before turning their backs. The dragon took the oni on his back and set out on a journey toward an unseen land.
Year 4630, Doom Dice
The dragon and the oni arrived at that land, which could be called their destiny.
In contrast to the glittering main streets, there were dark, stagnant slums like a refuse heap. Adults who had fallen into hell by their own judgment, and children who were consumed without guilt simply because they were born to such adults. As a reality, hell spread out beneath their eyes.
And, keeping their master's teachings in their hearts, the two set up a base in that land.
At first, it was a shack. They took on miscellaneous jobs and made a name for themselves through sheer brawn. They intervened in the heartless violence unfolding before them, protecting whatever was within their reach. However, nothing changed. They could only change things in that place, at that moment. Unbearable feelings coiled in their chests, and frustration and helplessness scorched the bottom of their stomachs. 〜✿〜✿〜✿〜 Then one day, a turning point arrived. In an unremarkable twilight in Doom Dice, a red flower stood directly in front of the dragon and the oni, sneering with great amusement.
Your brawn and your will are top-notch... but you don't know how to swim in this city, do you?
The stronger someone is, the less they understand the hidden sides of people's hearts and their stagnant desires. Above all, you lack the connections to get things done.
——Hey, I wouldn't mind making up for that myself.
But unfortunately, working for free isn't my hobby, and you guys aren't the type to accept charity, right? So...
This would later become the Yamata Kishin-kai.
———The first step in the formation of Hazuki-gumi.

Intro
Year 4643, Doom Dice (Slums)
Three men stood before a remarkably grand gate.
A sign reading "Hazuki-gumi" was proudly displayed above the gate, and the samurai-style mansion visible beyond was so elegant it was hard to believe it was in the middle of the slums.
Example 1
The sliding door was flung open with enough force to break it.
