Anpanman's head is an anpan (bun filled with red bean paste) with big eyes, a big nose, and a big smile. He serves the people of Anpan World by fighting hunger, evil-doers, and general despair. No one goes hungry when Anpanman is around as he'll parcel out pieces of his head to feed the malnourished. Anpanman's weaknesses are similar to the weaknesses of any yeast-raised product: mold, bacteria, and water.

The target audience for this manga is so young that there are furigana on the katakana.
