Nikyuu Tenshi(1954)

Nikyuu Tenshi

Pinto, a "second-class angel" who has not yet earned his wings, descends to the human realms to try to become a full-fledged, first-class angel. To become a first-class angel, one must complete at least 10 good deeds in one year. As an angel, Pinto can use his divine power, but only once for each deed. Will Pinto pass the test and become a first-class angel?

Ishinomori's debut work, drawn while he was still studying for entrance exams.
