This is an exploration RPG where you control the female protagonist Seryna Ryoyo and wander around the night school. By exploring various places such as classrooms, toilets, and the rooftop, masturbation scenes will occur. The degree of lewdness increases through masturbation scenes, and erotic progression occurs through events. At the same time, the standing pictures also change, and animations such as breast shaking and hip swaying increase. There are achievements for various actions, and you can collect a total of 50 achievements. There are 5 endings, and after clearing, you can choose to return to the end with achievements preserved or to start over. By clearing once, you can unlock all reminiscences, obtain skills advantageous for scene collection and repeat play. The playtime is approximately 2 minutes at the shortest, and normally it is expected to be 1-2 hours.
