Shanshu is the setting for the anime series Yuki Yuna is a Hero, which follows a quartet of school friends navigating a strange, enchanted forest. It's a magical place, so it makes sense that its music would be similarly full of colour, fantasy and whimsy—sweeping violins, bittersweet vocals and energetic electronic beats. But you don't have to be an anime aficionado to appreciate "Aurora Days" and its heartbreakingly nostalgic, weaving melodies.
