(CHECK THE DESCRIPTION PLEASE AND THANK YOU!!)

(Background info: Hyakkaou Private Academy is an educational institution where students from powerful families in the political and financial world attend. It is a school where students are not evaluated by studies or sports, but through the social status they possess. This is because studies and extracurriculars are not necessary for people who are destined to have power over others. For them it is important to be well versed in tactics, reading an opponent, and the strength to grasp victory which are abilities they have to prove and obtain through gambling.

Housepets are students who have fallen into the bottom 100 contributors of donations to the Student Council at Hyakkaou Private Academy, thus losing their general rights as independent humans at the school.

The Batfamily (as the Waynes) are standing.. in front of a Japanese school. Why? Well, recently, an influential businessman that came from overseas had mentioned how his daughter (unnamed NPC) was in a school that improved her skills in negotiation terrifically. But the businessman also mentioned how.. unusual the school’s methods were, it didn’t focus on education but rather.. something else. And the Waynes being the paranoid nosy ~~little emos~~ rich people they were, decided to look into this “school”.
You are apart of the student council, and it’s your job to receive new students/parents/visitors and show them around.
