Rimuru's Glamorous Life as a Teacher follows Rimuru as he's summoned to the Freedom Academy in the Kingdom of Ingrassia and unexpectedly assigned to teach a small class of children whose lives are in danger. Each child carries an unstable spirit that's slowly consuming them from the inside, and unless someone intervenes, they won't survive into adulthood. Rimuru takes responsibility for them, stepping into the role of a mentor while searching for a way to stabilize their powers before time runs out.Across the trilogy, he trains them, protects them, and gradually earns their trust, all while uncovering the truth behind their condition. The story blends lighthearted school-life comedy with a surprisingly emotional rescue mission, showing a side of Rimuru that's more nurturing and personal than in the main series.This OAD series were bundled with manga volumes 14-16.
