Manabu Honma (本間 学 Manabu Honma) is Menma's father.
Manabu is a very serious person who hopes his wife will face reality and get over the tragic loss of their daughter. He did not allow Menma's childhood friends to make fireworks for granting his daughter's wish. Later, due to the request of Yukiatsu, he finally allowed them to make fireworks. On the day that the fireworks lit, he accompanied his wife to see the fireworks made for Menma.
Manabu is a middle-aged man who has short gray hair, brown eyes, and glasses.
