- Names to Know in Anime
- Takehito Koyasu -- Satoru
- Megumi Toyoguchi -- Mayuzumi
- Masashi Ebara -- Yomogi
- Aya Hisakawa -- Utsumi

- What Could Have Been: In the game's data, complete sprite sheets for Hotori and Sayaka can be found, implying that they were meant to have a bigger part in the main story.
- Also, Takumi Nakazawa originally wanted the game to start on November 11, 2011 (making the game start on 11/11/11), but then he realized that the weather conditions in November wouldn't be good enough to trap everyone in the mountains, so he compromised on January 11, 2011 (1/11/11).
