Roland♂

A young soldier fighting to free his motherland from the grasp of its invading neighbor. Concluding his training in the Free French Forces, he enlisted into the newly-formed French Special Air Service. A fair young man, brimming with a sense of justice and bearing no falsehoods in his heart, he obstinately clings to what he thinks is right, but is also prone to self-righteousness. During the invasion of Normandy, unforeseen circumstances cause him to lose his way in the interstice between this world and another.
