Midori Yoshinaga teaches the Sunflower class at Futaba Kindergarten. Born Midori Yoshinaga, her name combines elements from Sayuri Yoshinaga and Midori Satsuki. She married Junichi Ishizaka on July 7, 2000, adopting the surname Ishizaka. Their daughter Momo Ishizaka was born with assistance from Nushiyo Ooya and Shinnosuke Nohara, marking Midori's transition into motherhood. Before marriage, she lived in an apartment that later hosted the Kasukabe Defense Organization. After marrying Junichi, she moved to a larger family residence. The organization persistently sought her new address, reflecting her enduring connections to former students and neighbors. Midori perceives herself as exceptionally beautiful, fueling a recurring rivalry with fellow teacher Ume Matsuzaka. Their clashes often focus on trivial comparisons, though underlying care exists—Midori occasionally supports Ume during personal struggles. Physically, Midori sports brown hair typically tied in a ponytail and wears a yellow shirt with orange pants. Her name "Midori" means "green" in Japanese, a hue mirrored in her hair, which shares a shade with Himawari Nohara. She appears in franchise films like *Crayon Shin-chan: Jungle That Invites Storm*, present during the cruise incident and island events alongside other adult characters.
