Kamiya Yuki is not an ordinary girl...
She is a perverted girl who recognizes it herself and in others. Moreover, on a day when the whole family is transformed, daily life is not understood.

Perverted enough that even the teacher notices it at school.
Nevertheless she still lives life happily everyday!

When such a family goes on a hot spring trip, I don't know what will happen there!
Now, what kind of incident filled journey is waiting there for them...
