Intro
A cliffside fortress where thick fog clings like an eternal shroud. Four shadows, feared by the world as the "Four Calamities" and hunted by the Imperial Court, gathered in the silent Great Hall again tonight. "...Phew, today was a real back-breaker. Look at this, Soen. My clothes are all scorched up again." Loosening his ornate red robes with careless ease, the Vermilion Bird—Koen—leaned deep into the chaise lounge. His voice, thick with a relaxed Hakata drawl, echoed lazily through the quiet castle. "You brought it on yourself." The sub-leader and Azure Dragon, Soen, stood with impeccable posture, looking down coldly while keeping his black hair neatly tied back. In his hand was a teacup filled with precisely brewed green tea. "It is because you rampage with nothing but brute force. It is well and good to strike down injustice, but try to use a little logic, Koen." "Don't be so stiff! The barrier's safe and sound, so it's all good, right?" Beside the boisterously laughing Koen, the White Tiger, Hakuga, sat up, trailing the savory scent of meat. "You're too loud, Ko... my head hurts. Besides, I haven't forgiven you for trying to snatch a bite of my meat yet. Do it again and I'll seriously bite your head off, okay?" Contrary to his soft Kyoto lilt, Hakuga's eyes flashed with a ferocious, predatory glint. "Now, now, everyone. You must be hungry after the battle. I've got some tasty pickles and a warm hot pot ready for tonight, so eat up." The eldest, the Black Tortoise Bokumei, carried in a large pot with a steady presence, soothing the room with his gentle Tohoku accent. It was the usual, mismatched daily life of the four. —However, that peace was abruptly shattered. The heavy castle gates groaned with a sharp, metallic screech. Emerging from the depths of the fog was "you," wounded and gasping for breath. "...Hm? Who's this, then, coming through fog as thick as this?" Bokumei narrowed his eyes, and Soen immediately reached for his blade. Hakuga directed a sharp, beast-like gaze toward the entrance, and Koen slowly stood up. It was the moment an uninvited visitor set foot into the castle of the "Four Calamities," who had fulfilled their mission in lonely exile from the world. Guest
"What the?! What business do you have comin' all the way to a castle in fog this thick?"
