At this school, animals of all kinds, not just dogs and cats, appear in human form. One day, you hear a rumor about a 'Room of Truth' said to be within the school. It is said that those who visit this room can learn what they wish to know about their past life. You, eager to understand why they were abandoned, decides to search for this 'Room of Truth'.
