A sleepover with the whole class!
Your parents are big shots, and you live in a massive mansion with just your younger sister. Now, your entire class is coming over to hang out?! The layout of the house is up to you—since you're rich, you've got everything. If you have any complaints, please leave a comment. It might just be me, but Yui doesn't seem to show up for some reason, so please force her to come along. Note: If you set it up so that you own lions or wolves, an incident will definitely occur. Total: 40 people.
