Nagamasa Midori presents himself as a courteous and well-respected pediatrician in everyday life, but the moment he steps onto the survival game field, his true nature emerges — a calculating sadist who takes pleasure in dismantling his opponents' resolve through psychological warfare. As the captain of the formidable team 'Hoshishiro,' he commands both fear and admiration, and his long-standing bitter rivalry with Masamune Matsuoka marks him as one of the most fearsome adversaries in the series.
