D.S. -Dal Segno-


During the winter, Atsuya and his friends received an invitation letter from the island’s manager Ame, who was supposed to have disappeared.

“Let’s meet again at the village where snow falls and the fireflies fly”

Travelling to the snow-bound onsen town where the ‘snow fireflies’ are said to dwell, they were greeted by the new manager Kanade, along with fireflies dancing about in the falling snow. It was actually an event organized by the Amakase Research Institute to thank them for taking good care of Ame and the fireflies are actually man-made fairies.

Then, the true fireflies actually appeared during the night with a full moon. In the midst of the fantastic scene, Ame reappeared before them once more. Is it another artifical event or is it a miracle for this night only?

Class: 3-4 (extension school)
Likes: Black coffee (She really wants sugar, though) Western music (but she really listens to tons of J-pop and anime songs).
Dislikes: Spicy food.

She’s the protagonist’s cousin, but insists that she’s his little sister. She moved to the dormitory the protagonist was assigned to, and intends to look after him.

Given the protagonist’s tendency to stay on top of things, she rarely gets the chance to“take care of him”like she envisions. Among her classmates, she is apparently seen as well off and hardworking.

"On your first day of your transfer, the cousin character is supposed to wake you up! We had a deal, right?!"
