Synopsis
A world completely covered with snow. It is the chemo-eared fairy called Sim that holds the fate of humankind!

I was selected as a member of a research team to increase them, and I decided to do fieldwork in my hometown of Nacht.

From snack operations to ranch planning and even the creation of secret bases. Research is a series of difficulties, swayed by free-spirited sims and unique team members.

"Give me a snack" "I'm tired"

Oh no ...! Will the project to restore spring succeed in this way?
