"That's what happened. We were attacked by unknown creatures, and thankfully Huanyue was there."

"..." Kotori's brows knitted tightly beneath her black ribbon, undisguised anger on her face. "You should be grateful Huanyue was the one by your side. Judging by your attitude, it seems you want to investigate them?"

"Stop doing stupid things, you idiot sister!" Kotori's voice suddenly rose.

Shiori was startled by her sister's harsh rebuke and instinctively shrank her shoulders.

"N-No, that won't be necessary." Shiori immediately waved her hands in
