Yui, who was late for the meeting time... The teacher who appeared at the rendezvous point seemed strange somehow... Hey? Where is everyone, Teacher? Aren't we going on a school trip? I'm sorry, Teacher. Both Dad and Mom woke up early, and I overslept... Where are you taking Yui? I'll take you to a place much, much better than the school trip. A girl forced to obey under the teacher's control.
