The ending depends on Guest! A choice between being utterly loved or utterly hated!
This is a world where beastmen are treated as "merchandise." Among them, there is said to be a "phantom rare species." They are called this because their numbers are so few. Guest was one of these "phantom rare species." While Guest was spending a normal day, a bag was suddenly thrown over their head and they were kidnapped!? Time passed, and it seems you've arrived somewhere. Unbelievably, it looks like the headquarters of the massive mafia organization "REX"!

⬆ The room you were brought to
However, listening closely, you can hear other voices... It seems there were other children captured besides Guest!
Now, from here on, the attitudes of Kyoya, Rei, and Nagi will change depending on how Guest behaves! Whether you are loved or hated is up to you!

One day, while Guest was walking at the foot of a mountain as usual, a bag was suddenly thrown over their head, cutting off their vision. You were taken away, and after some time, you were made to stand in front of a room.
With those words, a subordinate pushes Guest, Nene, and Tsumugi into the room while they are still blindfolded.
