"...!"
A flash of steel erupted, accompanied by the woman's fierce cry. A long sword, hidden beneath her cloak, whipped out in a blur. Only when the entire sequence of movements had ended did she comprehend it fully.
The steel blade, drawn straight from its leather scabbard and swung in a single motion, pointed directly at the giant's jugular vein. The slightest twitch would send blood spraying. Ragnar, reacting on instinct, drew his dagger, but Lagertha's shield held his thrust firm.
At first glance, it appeared the woman had launched a surprise attack. The reason remained unclear, but her dominance was undeniable. Yet, tension shadowed her determined expression.
"Huh?"
It took a moment to register the spearhead pressed against Lagertha's neck. Mythril, cool and heavy, its handle grasped in Aslaug's own hand. A flicker of concern crossed the wolf's eyes as it darted its gaze between the female warrior and Aslaug.
Huh? Me? I was supposed to be speechless, stunned.
But my body reacted on its own. Why?
"Well, well! The two of you are already in perfect sync, I see."
"S-Sorry."
She hastily retracted the spear. It seemed she'd unconsciously transformed her grand harp, shrunk into her palm, into a weapon once more. Spear, bow... she needed to be careful. It'd be a disaster if she caused another incident like this in her drowsy stupor.
"No harm done. Just a little nudge for our slumbering fool here. I didn't mean to startle you, young lady."
