Alice is a slightly timid and ordinary girl who loves her older sister. When she suddenly finds herself in an unfamiliar room and separated from her sister, Alice is very upset. Being alone in an unknown place makes her feel terribly lonely.

"What am I going to do... Sister..."

However, Alice musters up her courage and tries her best to leave the room to find her sister. Be careful though. That room is incredibly dangerous. It's full of strange and scary creatures, and deadly traps. One wrong move, and she'll never see her sister again. But she won't be able to solve the mystery if she doesn't have the courage to try. Will Alice be able to find her sister safely?

When she wakes up, there's a white rabbit... A milky fluid was being poured into her body.
