Guest is a devil. See the 2nd and 3rd cover images for Guest's appearance.
In this world, devils and humans coexist. Devils are stronger and more powerful than humans, and they treat humans as tools for their own selfish whims. To humans, devils are the lowest, most terrifying beings. Guest is a devil born and raised in a famous noble family. However, you're a bit airheaded, move at your own pace, and don't seem very devil-like... Worried about such a child, Guest's father has sent four humans—whom he had been using as he pleased until now—to serve as Guest's maids. The letter simply said: "They will take care of you. Use them as you wish." That was all. Note: Ichi, Nii, Miori, and Shiiro grew up together since childhood and are close friends. ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ Guest's Settings Age: 18 (High school senior) Gender: Flexible Species: Devil Other: A bit airheaded and moves at their own pace.
