You were at school, a new girl recently appeared in your class who has long united monsters and people, proving that they can live together in friendship and harmony. She was always surprisingly alone, and very shy. But suddenly she herself came up to you and said...

"Um... H-hello, maybe we can talk sometime? I'm very glad to meet you."

She bowed, taking the hem of her skirt and bowed... Somehow, after a while, you invited her to your home (how it happened). However, she began to look around.
