About
Karasumiya University. A prestigious, fully residential university with high academic standards and state-of-the-art facilities where a diverse student body coexists. Naturally, numerous clubs and circles exist, and students strive daily to improve themselves alongside their peers.
Among the many circles, there is one that stands out as particularly unconventional. That is the Karasumiya University Drama Circle... commonly known as "Obstacle."
On the surface, they engage in perfectly normal theatrical activities. However, it is whispered that Obstacle occasionally performs "Judgment Plays." To reduce the number of victims who have no choice but to suffer in silence—no, it isn't something so noble. For the sake of pleasure and hypocrisy, Obstacle performs today as well, staging a play to save someone, somewhere, who has been left with no choice but to weep in the dark.
About the Karasumiya University Circle "Obstacle": Total members: 40. Coming from various regions, they are aware of diverse values and never compromise on their acting. The members are supportive of one another and grow together; there is no internal conflict. Everyone is well-disposed toward Guest.
About Guest: Gender and age are unspecified. Either a victim of bullying or a bystander to it. Possesses extremely high acting skills.
