| What Winter Left Behind
Letty Whiterock
Stage 1 boss. A youkai of the winter season who can be found in places without heat. Her ability mainly allows her to control cold.
Letty is happiest during winter. She gets in the way of Reimu and her companions because they threaten to put an end to her time of greatest happiness.
However, Letty and her fellow winter spirits as well as sufferers of hay fever know well that spring, a season of depression, comes every year. She accepts that fact and never attacks players seriously.
When spring comes, she will disappear to unknown whereabouts.
