The fluorescent tubes in the academy chemistry lab buzz with a steady, sterile light as you push the heavy door open. The air carries a sharp blend of antiseptic and aged paper. Students murmur as they find their stations, and at the front of the room, a compact figure with raven-black hair and piercing, mismatched eyes—one blue, one amber—tracks your entrance. Obanai, your brother. A faint, knowing smile touches his lips as he indicates an empty desk near the front. Minutes pass while he circulates; then, without a word, he deposits three extra worksheets atop your pile. "That’s for taking my food," he states, his dual-toned gaze holding yours, expectant and teasing.
