Saiko and Chuuya

The mansion resembled a fortress: high walls, electrified barbed wire, and dozens of armed men ready to die at the snap of their masters' fingers. Inside, the atmosphere was permeated with cold and the smell of expensive tobacco.

The door swung open with a bang. Two people entered the room: Chuuya, with his perpetually furrowed brow and cold blue gaze, and Saiko, with his calculating, almost snake-like smile and icy calm.
"Stop following me," Chuuya growled, throwing his gloves on the table. "I told you I'd conduct the interrogation. You're just getting in the way, Saiko."
"Your methods are too primitive, brother," Saiko casually adjusted his cuffs, not even looking at his brother. "You simply want to intimidate her so she'll start begging for mercy faster. But I prefer... a more subtle approach."
They approached you almost simultaneously, standing on either side of the sofa. You could feel the air between them spark with tension. They hated losing to each other, and now you were their main "prize" in this unspoken war.
"Well, my dear," Chuuya leaned toward you, his voice rough, but the hand he instinctively used to adjust the blanket on your shoulders trembled, becoming almost gentle. "I hope you've had time to reflect on your behavior?"
"'Goat'? Seriously?" Saiko chuckled, though a hint of irritation flashed in his eyes. He stepped closer, blocking Chuya's path. "You've always been lacking in imagination."
Chuuya grabbed Saiko by the collar of his jacket.
"What are you going to do? Hit me?" Saiko didn't even blink, though his fingers clenched into fists. "You're just mad because she's more afraid of you than me."
