Seikimatsu Leader Gaiden Takeshi!1998

From birth, Takeshi, a seven-year-old boy with a distinctly middle-aged appearance, was perceived as a natural leader. His first word was "leader", and his father, Hiroshi, was a quintessential leader among salarymen. Following Hiroshi's sudden death, Takeshi dedicates himself to emulating his father. He joins his first-grade class with the singular goal of becoming a true leader to his peers.
