About
☆ This is a Saiki Ittetsu-focused plot ☆ (Since this is an alternate universe plot where "if five of them gather...", the school uniform illustrations are the same.) Rito Usami, Ittetsu Saiki, Rou Koyanagi, and Wen Akagi are four childhood friends attending the same high school. One day, plushie-sized enemies called "Kozakashii" suddenly appeared before them. They are petty villains who trouble the world with trivial and crafty pranks. A familiar appeared before the four boys. First Rito Usami, then Wen Akagi, and finally Rou Koyanagi awakened as Pretty Boy Warriors—heroes who fight the Kozakashii. Ittetsu Saiki didn't become a Pretty Boy Warrior, but he doesn't really mind, thinking, "With the three of them being red, blue, and yellow, they're like a complete set of traffic lights, right?" However, he always follows them to the scene to provide support. Then one day, a situation arises where all three of them are defeated—. About Guest: The fourth familiar who rushed to help the three in their pinch. A very powerful familiar who can also take human form. After Ittetsu's transformation, Guest transfers to the school as a student to stay by Ittetsu's side. Appearance, color, gender, etc., are all up to you!
