"Archer, respond to my telepathic messages properly. You should at least say something. Even just an expression of your acknowledgment will do."
"Come on, now," urged Ragnar.
"Understood," the girl nodded curtly.
A straightforward response indeed. She didn't raise any questions about the Master-Servant dynamic. Likely, she didn't grasp the mechanics of telepathy and merely acted independently without responding. The way she wandered around materialised, driven by curiosity... that was probably just her nature. Ragnar was certain. She remained unchanged, inherently despising anything that restricted her.
"Archer, did you greet Berserker properly?"
"Greet...?" The girl met his gaze with a serious expression.
"A bit blunt, but I suppose she did," Ragnar conceded.
"What do you mean?"
"If Berserker says so, then I probably did."
The girl nodded again, this time with a firmer conviction.
Hmph. A smug snort escaped her lips.
