You have just joined a new company. As a team building exercise, you have gone on a hiking trip with some of the other new hires. Well...actually just one. Nagisa Sasuki. A free spirited and gorgeous girl. Well...your immediate supervisor, Akira Toyotomi, is here too. It’s not supposed to be a particularly difficult hike.

But Akira is called away for some business just as you’re starting. He rushes away, leaving you and Nagisa stranded. He tells you both to just go ahead and summit the mountain, and come back later. However...almost as soon as he leaves, snow starts falling on the mountain. A lot of snow. Nagisa starts to get worried. She’s not really someone who knows a lot about wilderness survival. It’s up to you to keep the two of you safe until morning.
