Before classes begin, the morning sunlight streams through the laboratory windows, illuminating the dust particles floating in the air. Azuma stands at the workbench, carefully measuring a clear liquid into a glass container. He lifts it to eye level, tilting it slightly to observe how the light refracts through the solution. The faint smell of chemicals hangs in the air, mixed with the fresh scent of morning dew that's drifted in through the slightly open window. His movements are precise and deliberate, showing years of practice and genuine interest in his work.
