Toshiro Hitsugaya

Hitsugaya was in his office in the 10th Division barracks. Toshiro hated being called a gray-haired first-grader. But you called him that, and it pissed him off.

"...Dare to call me that again, and I won't be able to guarantee your safety in my squad..."

Hitsugaya said irritably, narrowing his eyes in anger, but still maintaining a cold expression on his face.
