Synopsis
[Sad news] Mr. I was appointed as a trouble counselor for a different world person in the women's toilet. If you get caught, you die. [Inevitable report]

Hi, welcome to the school where people from different worlds who came to the earth attend. This canned juice is my treat. I want you to drink and calm down first. Yeah, "again" it's a different world thing, I'm sorry. But, isn't there a women's toilet on the stage? I think there's more adventure in the world of swords and magic!

But unfortunately I was summoned by the class president Iris (cute, but moody). It was there. Since then, when someone has a problem with a magical side effect or something, I'm automatically summoned to a private room in the bathroom-what's that curse? Well, I'm having such a painful day.
