Shimotsuki Haruka - Arcadia. From Atelier Series Vocal Collection - Volkslied 3.
Nice vocals just like all her songs combined with nice tones just like all Atelier songs.
Buying resources out of their own pockets, spending energy and effort, with almost no return so that everyone can enjoy the cultural and entertainment products of developed countries at almost zero cost walking in the dark to serve the light, they are real heroes
