htoL#NiQ: The Firefly Diary
In the depths of a labyrinthine ruin, a young girl named Mion rises from a deep sleep. Lost, alone, and with no memory of how she got here or where her parents are, she is greeted by two fireflies—one composed entirely of light, and another who lurks among the shadows.

At the bottom of an old ruin, a young girl named Mion awakens with no memory of how she arrived at this dreadful place. Guided by two fireflies, Mion must solve puzzles, outwit monsters, and avoid traps to escape the darkness!
In htoL#NiQ: The Firefly Diary, you will guide Mion's escape from her dark confines by controlling two fireflies—Lumen and Umbra. Direct Mion's movements as Lumen, and destroy obstacles as the shadowy Umbra. Untold mysteries await as you guide Mion to the surface, overcoming traps and puzzles along the way. But be warned—the shadows are never far, and they're always hungry...
