Upon release, ONSD 525 received mixed reviews. Hardcore fans of Mihiro were reportedly distressed by the content, claiming the "Exposure" theme went too far, damaging her innocent charm. Conversely, collectors praised it as the definitive "Best of" for Yuma Asami, arguing that her acting reached its peak when simulating genuine psychological distress.
