This story is set in Cambodia. War has ravaged the country year after year, leaving behind it large minefields. To this day, many people still suffer because of them. Aki Ra keeps clearing the fields. But what was his childhood like? This is the story of a real child soldier, a historical account of a tragedy humanity should never forget.

Mitsurin Shounen is also the story of a meeting. The one between Aki Ra, who grew up during the war, and Akira Fukaya, politically-involved mangaka and in love with south-east Asia.
